Practice estimate the product of a decimal and a 3-digit whole number. Round each of the factors to their left-most place value. Multiply the rounded numbers to approximate the answer
A. Multiply a 2-digit decimal number by a 2-digit whole number using partial products with an area model
B. Multiply a 2-digit decimal number by a 2-digit whole number using the standard algorithm (Level 1)
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)
