Explore a multiplication strategy that is useful when one of the factors is a multiple of 10. Break that factor apart into 10 and another factor, and then use the associative property so that you multiply by 10 last
A. Multiply a 2-digit number by 10
B. Identify a round number as a multiple of 10
C. Solve a word problem two different ways by regrouping factors
E. Multiply by splitting a round number into a multiple of 10 and regrouping factors based on a disk model (multiply by 10 first)
F. Multiply by splitting a round number into a multiple of 10 and regrouping factors (Level 1)
G. Multiply by splitting a round number into a multiple of 10 and regrouping factors (Level 2)
H. Rewrite an area model multiplication equation using the distributive property
I. Multiply to find the area of a rectangle using the distributive property
J. Multiply using partial products and the standard algorithm (one round number)
K. Multiply to find the area of a rectangle using the distributive property and the standard algorithm
L. Multiply using partial products and the standard algorithm
M. Multiply using the standard algorithm (one round number)
N. Multiply using the standard algorithm with regrouping (one round number)
O. Multiply using partial products and the standard algorithm with regrouping (Part 1)
P. Multiply using partial products and the standard algorithm with regrouping (Part 2)
Q. Multiply using the standard algorithm (one round number)
