3rd grade Lesson 10.7 on mean and median
(Click
HERE to see and participate in discussions about this on the IMI Discussion Forum.)
Here it is, the end of the year, and I'm pushing myself to keep teaching new math lessons and concepts with just a few days left. Yesterday I taught 3rd grade lesson 10.7 on the mean and median. I actually told a colleague that I was going to give it a shot, but I didn't really like the lesson when I planned and studied it, so I wasn't expecting much. The lesson had the children creating a bar graph from data, using markers to cover the squares on the graph, then using equal sharing to spread those markers out evenly, hence finding the mean. As I watched my students catch on to what we were doing much quicker than I had, I realized what an awesome assessment I was witnessing. The students were using so many skills while discovering and learning a life-skill of averaging that they will use forever! I learned! a valuable lesson--don't sell any of the lessons short, and keep your energy up because EM will never cease to surprise you with awesome lessons--even when we're worn out and ready for summer vacation! Have a great one, Everybody!


Charting mental math sores (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
The biggest motivator in my room has been that of using the 3-minute tests and having the students do the charting of their scores! This is the first year I have used the chart, and I have noticed a big difference in the level of interest and motivation. I admit it was very frustrating at first to have my fourth graders chart their own one-minute and three-minute scores. I can now say though that all are very proficient at it. They love seeing their growth - and I've noticed their willingness to encourage each other and praise others for their growth! Click HERE to join in the discussion.

Latitude/longitude lesson (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I used the enrichment lesson on page 411 of the teacher's manual to teach latitude and longitude. I used oranges and had the students draw lines, the equator, prime meridian, north and south pole etc. with red and blue markers (washable). It was a little messy since we used washable markers, but at least it would wash off! The children worked in partners and found it much easier to draw a straight line if one student turned the orange while the other student drew the line. The children loved the lesson and it made sense to them! It has been the best way I have ever used to teach this standard plus I could wash my oranges off and still eat them! Mary Lawrence, Valley Mills, Grade 4 in Decatur
Easy, useful tip for working problems
(Click
HERE to see and participate in discussions about this on the IMI Discussion Forum.)
Yesterday I was talking to a fourth grade teacher who shared with me a really easy, useful tip to help students to keep their columns staight when working multiplication or division problems. She has the students use lined notebook paper. They turn the notebook paper on its side so the lines are vertical---instant columns used to line up numbers. I thought this was a great idea. We are multiplying multidigit numbers using partial products, and one of the most common mistakes that is made is that students do not line up their numbers correctly. This is a great solution to this problem. Becky Noble, Dixie Bee Elem, Grade 3 in Vigo
Celebrating Milestones on Scrolls
(Click
HERE to see and participate in discussions about this on the IMI Discussion Forum.)

We celebrate each milestone on the scrolls ( every time a student makes one thousand or an increment of 1000,) by presenting the student with a Certificate of Achievement, signed by the teacher and the principal. Then they are listed on the classroom pocket chart of the "Thousand Club". Each member who has made it to 1000 is represented on the chart with a piece of colored construction paper with their name on it and a shiny gold seal. We use different colors for each increment of 1000. The students really like receiving their certificate and official handshake when they reach this milestone! Ann Filler

Math Egg Hunt (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I know that Easter is over, but this activity can really be used anytime. On the day before spring break, I hid 50 plastic eggs in my classroom. Each egg contained some sort of math problem. I tried to include lots of different math skills----basically a review of everything we have covered this year. Students were given an answer sheet which was numbered 1-50. Armed with a clipboard, pencil, piece of scrap paper, and an answer sheet, students went from egg to egg. The problem inside each egg had a number at the top left corner. The student worked the problem and then recorded the answer next to the corresponding number on the answer sheet. Students were given the choice to work in pairs or alone. When a student had ten correct answers (verified by me) on his or her sheet, he or she got to get a treat out of the goodie jar. They were having so much fun, they didn't realize that they were working! Becky Noble, Dixie Bee Elem, Grade 3 in Vigo

Cube Drop Experiment (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
Hey! Just a little advice for fourth grade teachers who have been struggling with the cube drop experiment. The first year I did that experiment I did just what the book said and I tried using the centimeter cube for the experiment. It didn't work because the cube bounced every time and it took 1000 drops before the kids got 50 that counted! We tried doing it on the carpet in the pod the next year, and that worked no better. The only way they wouldn't bounce was if the kids were two inches from the grid, and then they could plan where they would drop it! I finally figured out that we could use modeling clay, rolled up into cubes. It has just enough stickiness to it that when it drops onto the grid, it sticks rather than bounce. A few rolled off, but not many. Using the clay doesn't take anything away from the effectiveness of the lesson and helps you and the kids keep your sanity!  Julie Pearson, Orchard Dr. Elem., Grade 4 in Hammond
Fraction Cards (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I just wanted to share or remind everyone of a tip someone gave me last year, and has been helpful even this year when I'm in a new grade level. The fraction cards that are in the back of the student journal are wonderful for all the games and teaching of equivalencies, etc. But, if you allow the students to tear and cut them out themselves, you might get in trouble. If the students don't cut exactly on the lines, the cards are useless. What I did was had the students pull out the pages. I had them laminated, then I cut them out. I labeled sets, just like I did with the EM card decks, and rubber banded them together, so that when kids are ready to play the games, they have a full set that are very durable. Yes, it took me a long time to get the cutting and labeling, but it was time well spent, and I have fraction card sets for the next several years, I hope. I think that in the future, I can have the students take their pages home and they can play fraction games with their families, because we're all set at school! Diane Ragsdale, West Newton Elem, Grade 3 in Decatur
Assessment games (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
Now that I'm in the second year of EM I'm becoming more adventurous. I have started sending home a weekly game activity for homework by using the CD. I go to the Alternative Assessment Options under the Assessment spot. I choose a lesson and then send it home with a parent/student comment sheet, along with any needed supplies. Last time I received several positive comments from both parents and students. This is just another way of communicating with the parents about the math program since we don't send home the Math Journals. Marsha Bittner, Edgewood Elem, Grade 3 in Anderson
Geometry Simon Says (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
 My students and I play Geometry Simon Says. They get such a kick out of it! A line segment is hands out with two fists. A ray is hands out with one fist and the other hand just open to kind of make a backwards arrow. A line then is two backwards arrows. (Since we cannot make arrows with our hands the kids thought this would work well.) We then add things as we go through our unit. Acute angle we make an angle with our arms that forms an angle smaller than a right. Right - one arm straight up, one straight out the the side. Obtuse - one arm straight out to the side and one out to the side to form an angle bigger than a right. The class really enjoys coming up with ways to add to the game using geometry terms. I will say, "Simon says Ray" and they form a ray....when we really get going I will just say, "Right angle." Anyone who forms a right angle is OUT! I didn't say SIMON SAYS!

Everyday Math Games make indoor recess lots of fun!  
(Click
HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I am a Second Grade teacher in my third year of Everyday Math. It seems with the cold of the winter months that indoor recess becomes an everyday affair. We seem to stay in even for the slightest chill. The Everyday Math games have been a lifesaver for my children. Each year as I introduce a new game(s) in a unit, I prepare a shallow game tub for that particular game. In the game tub, I have everything needed to play the game (enough for 4 players---that would be two games of two players OR 1 game of 4 players)—plenty of copies to get us by for awhile, dice, cards, dominoes, pencils, etc. I include game mats that are often copied and inserted inside wipeable transparent sleeves. I copy the game directions from the “Games” manual or Math Journal, enlarge them for second grade readers, and put the game rules inside a plastic sleeve and into the game tub, as well. The game rules are very helpful for children who have forgotten the rules over time or are disputing a rule OR for the adult that supervises indoor recess. As time passes, I accumulate a number of games on my window ledge, which are available during the day when work in any subject area is completed early, but more so during indoor recess. By the time we get to the winter months, I have almost 20 games on my shelf. In addition, to the games I have their scrolling out, other routines we’ve learned and the unit explorations for the unit we are currently in. I have found that often on our exploration days students have not been able to have the time they really wanted with some of the explorations---so they have an opportunity to revisit them. I trade out explorations for every unit—so my offerings don’t always look the same. There is always lots to chose from. The children have lots of fun and get lots of extra practice in the meantime. Often math games win out over a movie or general play during the recess block. In addition to this, the games are ready for our After School Math Games Club, which we hold once a week from January-March. Linda Afdahl, Franklin Elem, Grade 2 in Vigo

Informal Assessments/Exit Slips
(Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)  
I use exit slips quite a bit and in several of the ways you suggested. My math block is right before lunch so students hand the slips to me as they leave the room. I usually make it a quick assessment. I ask them to explain a vocabulary word, solve a problem (or a couple), explain how to solve a problem, or write a question they have about the activity we did. When I first started exit slips we did them every day for about 2 weeks so that we got the routine down. Now I try to do them 2-4 times a week depending on how things are going. Students know that items that are on the exit slips will probably show up on our Friday assessment. It helps to clue them in on the "big idea" for the day. The exit slips give me a quick assessment and sometimes I'll incorporate a similar problem into the next days math message if I notice several students struggled. Hard as it is to believe I have several students who ask if we can do exit slips almost every day!

Just the Facts (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
We have a schoolwide Fact of the Day. If the numbers in the fact are 9 and 4, the first and second grades do 9+4 and the 3-5th grades do 9x4. The children write the fact on all of their papers all day long. They write the fact family. They are asked about the fact in the cafeteria by the principal. The fact is written on every teacher's board, both inside and outside the classroom. Hopefully this helps a few students to learn more of their facts.

Math Messages for an extra grade
(Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)

 I went to the Wright Group Web Site that John has posted for us in resources and copied the Math messages onto paper. I copy each of the pages by unit and use them for the students to paste into a spiral notebook that I cut in two so that one notebook is now two separate 8 1/2" by 6". We cut the notebooks on the paper cutter and then used a wire cutter and bent the wires under the spiral intact. The kids love to use these smaller size books and I hand out the small strips of paper for each lesson and they glue it into their special math book and solve the problem on the same page. I use these for an assessment grade once each grading period and it gives me an idea of how well they are doing on problem solving and also gives them some accountability for the Math Messages.

Real Life Use of Money (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
My students are struggling with counting money and making change. Confused
I have implemented a "community" program where students can earn play money for being "good citizens" (NOT FOR GRADES) but attitude, responsibility, participation, etc. Each week, two new students get to be the "banker" and help participants "deposit" their earnings and make change as each student must keep $10 in ones at their desk for daily use. I have already been amazed at depth of understanding it is creating in counting money and making change.
Each grading period students will then use their money at an auction, bake sale, ice cream shop or Subway sandwich shop. I will need assistance in making change for this also. Very Happy Tuesday,

Number Names  (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I've been having a blast using number names myself whenever I need my students to go to a certain page or do anything numerically linked. An example would be...instead of saying,"Open your book to page 24," I say, "Open your book up to one dozen plus one dozen." They love the challenge of figuring the number out. If the number is big, just write the number name on the board. Be creative and have fun! Tuesday, Oct 12, 2004 Alicia Madeka, Kenwood Elem, Grade 3 in Hammond
Name collection boxes  (Click HERE to see and participate in discussions about this on the IMI Discussion Forum.)
I have used name collection boxes in a fun, hands on way both this year in second grade, and last year in third grade. I give each student a piece of sidewalk chalk and we all go outside where each student stands on a section of sidewalk (conveniently a square!!) I write a different number in the corner of each box and say "go" . Each student writes one name for that number and moves to a new box when I say "switch" . They love running for a new box and seeing what their classmate has written. They are not allowed to write the same name again and I monitor this as well as I can. We do this several times and then we discuss a few of the boxes. Also, last year at the end of third grade I made name collection boxes with each student's name in a box. They passed them around and had to write different, positive names for that student. It was a fun twist on a familiar math skill!

"I do calendar time in the morning. I don't like to record that temperature, because so little of the day is spent at that temp. So, we've been calling time and temp, checking our thermometer's temp with that, and then moving our classroom thermometer to reflect the day's high, not the current temperature." 09/13/04 - 09/17/04.  Sarah Hewes, Forest Park Elem, Grade 1 in Fort Wayne
