I was thinking about other patterns that I could make students aware of when they are studying multiples of a certain number and I starting looking at the multiples of 5.
I have always pointed out that the products end with either a 5 or a 0.
As I looked closer I noticed :
- that the numbers that end with 5 are the products of 5 and an odd number
- that the numbers that end with 0 are the products of 5 and an even number
Giving students an opportunity to look at patterns of multiples of a particular number on a 100’s chart can expand student’s thinking.
When studing their multiplication tables have students color code the number chart for math factors and multiplication tables.
They can print a different chart out for each number set, or work off of one chart. For example, color all multiples of three the same color. Do students see a pattern? Then color all multiples of four a different color from multiples of three.
The students wouldn’t have to print the chart, just write their reflections about what they noticed.
(Note: If students make a mistake while coloring their number pattern, they can select the white crayon to color the mistake and it will reset the square to a blank color.)
I’ll have to add that to my Multiplication Strategy Flip Book.
