Until this year, I never realized there were so many ways to multiply numbers! I will be doing a mini-series this week on multi-digit multiplication strategies since students will continue to practice using the strategies they've learned on a home learning "Problem of the Day" over the next several weeks. This week, we'll be practicing multiplying 3-digit numbers by 1-digit numbers.
Today we looked at:
Breaking apart factor(s) by place value is a basic strategy that is easy to understand and use for many of the multiplication situations we'll find ourselves in this year. It's also easy to visualize using an unmarked array.
We'll use this strategy again when we multiply two, three, and four-digit numbers, breaking apart both factors.
