This sort and solve was designed to give students practice looking at expressions in order to make decisions about the need to ungroup from the tens place.
It can be used with small groups to address standard specific needs, as a intervention or as an independent math station.
The first time students use the cards, they could just sort and check the cards. Subsequent sorts could include justifying their sorts and/or solving the expressions.
Sorting headers, answer keys for the sort and for solving are included, along with a page for students to justify their thinking and for the students to solve equations. An “I Can” statement recording sheet is also included.
This sort and solve supports 2.NBT.7 and 3.NBT.2
