This activity is designed to give students hands on practice with building two digit numbers, then subtracting groups of tens within 100. I personally love to use ten frames with this activity, but you can also you base ten blocks. Whatever your students are comfortable with will work! They could also draw it out if you place the activity sheets in a sheet protector for multiple uses.
All you have to do is print and you have a ready to go center or station activity!
Recording Sheet and Ten Frame Kit are included! Just copy the Ten Frame Kit on card stock for durability!
