Multiple Charts for Multiplication

As we moved further in our multiplication study, we began examining multiples charts. We have highlighted multiples of all numbers 2-12 and have found the patterns that exist between certain charts. For example, we recognized that the multiples of 6 are also multiples of 3 and that there are twice as many multiples of 3 as there are of 6. We also discovered that we skip count by an odd, even, odd pattern. We also discovered relationships between 3s,6s, and 12s.  Furthermore, students pointed out that 100 is not a multiple of 3,6, or 12. In addition, we began answering questions like, How many 3s are in 30? How many 3s are in 60?

We strategically place the students' multiple charts in their packets so they can make connections and find relationships. Below is an example of the work that students completed in class as part of their multiples study.  You will notice that the 2s, 4s, and 8s charts are all on the same page. On the next page are 3,6, and 12. 5s, 10s, and 20s are together, too. In addition, we place a 9s and 11s together and talk about their relationship to the landmark number 10.
