What do you notice? What do you wonder?
- Write as many other products in the table as you can. You may want to start with rows and columns that show products of 2, 5, and 10.
- What patterns do you see in the row and the column that show products of 5?
- Write some equations that show 1 of the patterns that you see in the multiplication table. Explain or show why your pattern happens.
