Use the related multiplication of two whole numbers to learn how to multiply a 2-digit decimal by a 2-digit whole number. Multiply the decimal by 10, then use the standard algorithm to find product of the whole numbers
A. Multiply a 2-digit decimal number by a 2-digit whole number using partial products with an area model
C. Multiply a 3-digit decimal number by a 2-digit whole number using the standard algorithm (Level 1)
D. Multiply a 2- or 3-digit decimal number by a 2-digit whole number using the standard algorithm (Level 2)
E. Multiply a 2- or 3-digit decimal number by a 2-digit whole number using the standard algorithm (Level 3)
F. Multiply a decimal number by a round number by factoring out powers of 10
G. Multiply a decimal number by a round number
H. Round a multi-digit number to a given place (Level 2)
I. Round a multi-digit number to a given place (Level 1)
J. Estimate the product of a decimal number and a 3-digit whole number (Part 1)
K. Estimate the product of a decimal number and a 3-digit whole number (Part 2)
L. Estimate the product of a decimal number and a 3-digit whole number then solve using the standard algorithm
