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