Students use this mat to play a basic number sense game used in the math series--TERC Investigations. I find that with the structure of the work mat students are more engaged and organized as they play.
First students put a number card on the 'I have' box and build that number using pennies or counters on the ten frame.
Then students turn over another card and place in the 'Change to' box. Students must change the amount on their ten frame to reflect their new number.
Students then move their number card over to the 'I have' box and start the process over again.
This game encourages students to compare numbers as they add/remove counters. It also builds number sense as students make connections between quantities that they have to add or remove as they change numbers. My kids are much more successful and focused at this game when they use the workmat!
