    Base ten Blocks

    Hi Elyse,
    Lots of our problem solving with double digit numbers involves the use of these blocks. We pose a problem of the day and the children are encouraged to use the blocks to solve these.
    There are several games you can play to encourage the understanding of carrying/borrowing. Cover a Flat is done with each partner having 1 flat. As each player rolls dice, the numbers are added and the flat is slowly covered with singles and rods (exchanging as needed) til one player gets the entire flat covered first. It can be done as Uncover a Flat starting with one flat each, and 10 tens rods covering the top. The object is to empty your flat first. Hope this helps. ;-D
