B47 — Connecting Multiplication to Division using the Open Number Line

Notice how this string is crafted? The first four problems are related and the last four are as well. The pairing in the string is different, but the numbers have still been chosen to support students to explore and understand the relationship between multiplication and division. Continue to represent these problems on the open number line to show the connections between the problems. The students will see the relationship between the problems and will begin to make use of them for future problems. Elicit a conversation about what is happening in the problems and why these patterns are happening. This will lead to a deeper understanding of the commutative property and the relationship between division and multiplication.
