Multiplying a Two-Digit Number by a One-Digit Number Using Strategies & Algorithms
T.I.P.S.
Students must be able to use sets of steps to multiply a two-digit number by a one-digit number using a strategy such as mental math, partial products, and the commutative, associative, and distributive properties.
Example
Kendra is trying to help her cousin solve some multiplication problems. Show two strategies that Kendra could use to explain to her cousin why 24 x 6 equals 144.
