Multiplication Skills and Facts
Activity: Multiplication Chart
In any grade, a student’s knowledge of the basic multiplication facts comes in handy – it is never too late to learn basic multiplication facts. This activity, among others, can be used repeatedly throughout all grades. Click on "Download File" to see the teacher and student pages.
How this activity is implemented does matter. It is important to know multiplication facts, but it is most important to make sense of them. I hope you take a look at the first attachment and try it out as suggested. How did it go? If you would like to, please provide feedback on the blog page.

Activity: Divisibility Rules with the Multiplication Chart
|
Divisibility rules can be introduced (or re-introduced) using the patterns in the Multiplication Chart.
It has been said that math is "the science of patterns" (Steen, 1988). Students really "get" math when they trust in those patterns. Rules and tricks don't cut it. If a student doesn't get the opportunity to make sense of a concept and really see the patterns, they will not value the mathematics. If you decide to implement this resource, you may find that students need help with the divisibility rule for 3. Once you have given them some time to struggle with what might be the rule, you can ask: "What happens when you add the digits?" However, the rest of the rules are pretty self-evident, and students should be able to answer them on their own (or in groups). Discuss them as a class once they have had some time to ponder :) ========================================== Reference: Steen, L. A. (1988). The science of patterns.
