Modelling Division allows students to create division problems that are then modeled with an array.

Follow the instructions to create a division problem. Try to solve the problem using any of the strategies you’ve learned so far. Click “Divide” to see the problem modeled with an array. Was your answer correct? How could you have used an array to solve the problem?

Division in Parts allows students to use an interactive model to solve division problems.

To use explore this interactive model, select “10 x10” and “Show Me.” Watch how the graph on the left models the division problem on the right. You can select a larger or smaller dividend to see different problems modeled.
