I purchased the materials from Hobby Lobby and made a Rekenrek, the Dutch counting device that we saw at our last IMI workshop. (See below for a picture of a Rekenrek.) The styrofoam base broke after I carried it around a few times. I am going to make a sturdier one with a wood base. It seems like such a valuable device to have in the classroom.

The Freudenthal Institute Web Site at http://www.freudenthal.nl/en/ has amazing games online at the link http://www.fi.uu.nl/rekenweb/en/
some of which include using a virtual online Rekenrek, plus others well worth visiting. (For example, see the game called Speedy Pictures.) I hope this can be useful to you as well as fun for your students!

If you are interested in the Rekenrek, there is a Mathrack available for sale at mathrack@comcast.net for $10.00. The Mathrack 20 has two row of beads (5 red and 5 white on each row). It is $10.00. The Mathrack 10 has one row of beads and is $7.50. I have not seen this, but received a message about it when researching the Rekenrek.
