I use this fun activity as a math center when we are learning about place value and building numbers out of tens and ones.
Students pick a number card and place it in the middle of their mat. They then use base ten blocks (images included in the pack) to build the number. We use the actual manipulatives, but I included images for any classroom that does not have these blocks.
I included all the teen numbers and 24 other numbers between 20 and 99. There are also 3 blank cards.
I have also had students complete this activity in pairs with one person being the “tens” person and the other being the “ones” person.
Thanks for looking!
