Slide 3 - Multiplication Using Arrays
- In the beginning of introducing multiplication, arrays are sued to provide a visual representation for students to actually see the problem as opposed to just memorizing facts.
- In this Mix presentation, examples of multiplication number stories and how to use arrays to solve those stories will be given and demonstrated.
