About the Mathematics in This Unit

Benchmarks/Goals Examples
Represent data including fractions on a line plot and solve addition and subtraction problems about the data.

Which is longer, the longest clear-winged grasshopper or the longest two-striped grasshopper? How much longer?

Two line plots. The first line plot shows the lengths of 16 clear-winged grasshoppers. The second line plot shows the lengths of 16 two-striped grasshoppers. d

Handwritten text reads: The longest two-striped grasshopper is five-eighths inch longer than the longest clear-winged grasshopper.

This is the first of three units in Grade 5 that focus on rational numbers (fractions and decimals). In Unit 6, students extend their work with fractions to working with adding and subtracting decimals, and in Unit 7, students extend this work with fractions and decimals to the operations of multiplication and division.

In our math class, students spend time discussing problems in depth and are asked to share their reasoning and solutions. It is important that students solve math problems in ways that make sense to them. At home, encourage your child to explain the math thinking that supports those solutions.

Please look for more information and activities about Rectangles, Clocks, and Tracks that will be sent home in the coming weeks.
