This product includes 48 different task cards, 2 answer sheets, and 2 keys.
This will help your students practice rounding to the nearest 10 and nearest 100, and then add or subtract their estimates. I like to use these products as activities in small groups, whole class, and as scoots. After we have completed these activities, I add them to my Math Zone centers as review games for the end of year testing.
My students as well as my team teachers students have loved these activities, and I hope your students will too.
You can also purchase these products separately in my TPT store.
