About the Mathematics in This Unit

Dear Family,

Our class is starting a new mathematics unit called Temperature, Height, and Growth. The focus of this unit is on using tables and coordinate graphs to analyze patterns and solve real-world and mathematical problems. In this unit, students learn about situations in which two quantities, such as temperature or height, are changing over time. They also study changes associated with geometric shapes, for example, how the area of a square changes as the length of its sides increases. Students use tables, graphs, and equations to represent how one quantity changes in relation to another quantity. They analyze patterns they can see in the tables or in the shapes of the graphs to solve problems and compare situations.

Throughout the unit, students will be working toward these goals:

Benchmarks	Examples
Use tables to record ordered pairs and construct coordinate graphs to represent the relationship between x-coordinates and y-coordinates.	Age (years) Height (cm) 0 (birth) 2 1 4 2 6
