Unit 1 - Multiplicative Thinking
We will start the year with a study of multiplication and division. Our focus will be on the use of particular strategies, models, and multiplicative comparisons. Click here for the Unit 1 Family Letter.
Models
The main models we will use in Unit 1 are number lines, ratio tables, and arrays. Parents, you may not be familiar with how we use some of these models, so use the resources below to familiarize yourself with them! Students, you may also use these resources if you need a little help at home.
Ratio Tables
The first few minutes of this video provide a basic introduction to how ratio tables work with a simple problem.

Number Lines
When watching this video, keep in mind that we would start our number line at 0 and draw the first jump of 6.

Open Arrays
You will also hear us refer to this method as the "Area Model."
