Students will rewrite horizontal subtraction equations into column subtraction. They will solve 2- and 3-digit problems within 200, with and without making exchanges into the 100s. Students practice this skill without prompts

A. Solve 2- and 3-digit column subtraction equations by exchanging 100 for 10 tens to solve

B. Solve more 2- and 3-digit column subtraction equations by exchanging 100 for 10 tens with or without prompts

D. Solve 2- and 3-digit column subtraction equations that require making exchanges into the hundreds and tens, with prompts

E. Solve 2- and 3-digit column subtraction equations by exchanging and regrouping with hundreds and tens

F. Solve 2- and 3-digit column subtraction equations with and without exchanging into the hundreds and tens
