This PowerPoint introduces three strategies for Multi Digit Multiplication focusing on Two Digits Times One Digit. The 3 strategies include: Traditional Algorithm / Standard Algorithm , Partial Products Algorithm, and the Box Method.
It takes your students through one method at a time step by step. Then there are a few practice slides that feature Beat the Clock. Students do the problem on a piece of paper or on white boards trying to finish before the penguin in the PowerPoint is done.
My fourth grade intervention students loved the contest aspect so much that they requested one with a monkey the next day.
You can use this to introduce one strategy per day or at any pace that fits your needs.
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
Fluently multiply multi-digit whole numbers using the standard algorithm.
