Section A: Summary Multiply and Divide Whole Numbers

Section Summary

We investigated some different ways to find products and quotients, making sure to estimate the value before calculating. For example, the product $49 \times 68$ is about $50 \times 70$ or $3, 500$ . We looked at two different ways to show the newly composed units.

We also found quotients using partial products and saw that there are many different ways to do this.

Divide. 1 thousand 7 hundred eighty 2 divided by 27.

The first calculation uses only 2 products but the products are more challenging to calculate. The second calculation uses 4 products but they are easier to calculate.
