Multiplication Posters!

Here are some ideas for multiplication posters.  Posters are thinking prompts for students.  They scaffold access into the content.  Do you have math scaffolds in your classroom?

Dr. Nicki,
I followed the link and saw two hands with five marbles as 2×5. I have been teaching my kids that 2×5 is counting by 2’s five times and that 5 counted twice would be shown as 5×2. I know it isn’t critical because of the commutative property, but I want to set my kids up for accurate understanding of the concept. Is my repeated addition is correct? Help!

Hi Lisa,

This is such an important issue. 2 x 5 actually means two groups of 5….remember that the “x” is read as “groups of” so this would mean 2 groups of 5. A good way to teach this is using circles and stars, where the students roll two different colored dice, one for circles and one for stars and then draw a picture and they write number sentences to represent what they have drawn. For example, say they roll 3 x 5 that would be 3 groups of 5. So the students would draw 3 circles with 5 stars in each circle. The addition sentence would be 5 + 5 + 5. The verbal statement is 3 groups of 5. The multiplication sentence is 3 x 5.
It does matter in that the commutative property represents the same amount but it is a different configuration. Think about it. If you say you have 3 groups of 5 people or 5 groups of 3 people, depending what you are doing, you need to know the difference. Give the students dinner table problems so they can think about what it looks like.

Happy Mathing,
Dr. Nicki
