Multiply two two-digit numbers with the help of an area model. Break one of the two factors into tens and ones, and multiply each part by the other factor using the standard algorithm. Then add the partial products
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
D. Multiply by splitting a round number into a multiple of 10 and regrouping factors based on a disk model (multiply by 10 last)
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)
