The Decimal Challenge

In this activity, students will practice adding and subtracting decimals. They will create expressions to match given criteria (e.g., the greatest value, the closest to zero, etc.). Students will reason abstractly and structurally, arguing that their expressions are the greatest or closest to zero possible. This activity has been added to our new K-5 Collection!
