C. Solve 2-digit column addition without exchanging using a place value chart model

D. Add 2-digit numbers without exchanging (Part 1)

E. Add 2-digit numbers without exchanging (Part 2)

F. Exchange 1s for 10s on a place value chart when necessary

G. Solve 2-digit column addition with regrouping with the support of a place value chart model

H. Solve 2-digit column addition with regrouping using the standard algorithm

I. Add 2-digit numbers with exchanging (Part 1)

J. Add 2-digit numbers with exchanging (Part 2)
