Students will practice solving 2- and 3-digit column subtraction equations within 200. Equations include making exchanges into both the 10s and 100s. Students are prompted to make exchanges when the ones and tens cannot be subtracted without an exchange
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
C. Solve 2- and 3- digit column subtraction equations with and without exchanging into the hundreds
E. Solve 2- and 3-digit column subtraction equations by exchanging into the 10s and 100s (Level 2)
F. Solve 2- and 3-digit column subtraction equations by exchanging into the 10s and 100s (Level 3)
G. Solve 2- and 3-digit column subtraction equations with and without exchanging into the hundreds and tens
