Virtual Manipulatives

We have been working on writing our numbers to 120!  Once we get to 100 we get a little confused on how to write the number.
For example, some of us are writing 10010 for 110 and some of us are writing 110 for 101, just to name a few of the errors that I am seeing.  So...this week we had some fun with base ten blocks, but not just any ordinary blocks!  VIRTUAL BASE TEN BLOCKS!

This website allows students to lasso groups of ten units, ten rods, or ten flats to regroup them into the next block.  For example, we have been lassoing ten units together to get a rod.  Once we had a rod we moved it over the the tens place.  This allowed me to show students why we write 120 and 1 2 0 and 10020.

Take some time to play with this site at home!  The kids will love LOVE LOVE lassoing the blocks together.
