5 × 9 Is More Than 45

5 times 9 A

Even though some students and teachers will chase multiplication facts, such as 5 x 9 = 45, in pursuit of memorizing the products, there is so much more waiting to be learned…

    Hey Steve! Love your work! You and your amazing work is an absolute asset to everyone. Thank you for always sharing openly. Just wanted to note that I use “math triangles” starting in grade 1 to show the relationship between the operations and the numbers. One thing you may want to add to your 9 x 5 is more than 45 is how the “answer”, in the case, 45, can be shown on the left side of the equation ie. 45=9×5. Even in grade 6, when I write this in the board, students tell me I’ve written the answer on the wrong side… which shows you their understanding of =. So, I always have students do the triangle, then write the 8 equations. Of course, In division they struggle with 9=45/5 and 5=45/9. But I think adding the “answer” on the left hand side is extremely useful. Anyways… thanks again for all your great work!

      Great point, Carla! My students are the same way. Equality needs more work!
