This lesson is Day 1 in a series of 5 lessons around U.S customary measurement.

This lesson focuses on measuring lengths to the nearest fourth of a inch, and discusses when it's necessary to find a precise measurement versus an estimate.

This lesson is Day 3 in a series of 5 lessons around U.S customary measurement.

This video lesson explores the use of appropriate units for measuring length. Additionally, students will be asked to solve single-step problems involving lengths of distances. No materials are needed for this lesson.

This lesson is Day 6 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson teaches students how to create bar models to compare lengths/distances. Students will need a piece of paper, ruler, scissors, and a pencil. These bar models will also be used for Day 7's lesson.

This short video and interactive assessment activity is designed to give fourth graders an overview of length (english units).

This short video and interactive assessment activity is designed to teach second graders about using real maps (english lengths and distances).

This short video and interactive assessment activity is designed to teach fourth graders about using real maps (english lengths and distances).

For this task, students work in pairs to estimate the measure of each person's foot and to determine the appropriate measuring tool to use. Once a measurement tool has been chosen, students measure the foot and record the lengths.

This short video and interactive assessment activity is designed to give fifth graders an overview of capacity - word problems.

This short video and interactive assessment activity is designed to give fourth graders an overview of capacity - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about distances between points on one route (metric units).

This short video and interactive assessment activity is designed to teach fifth graders about measurement: greater than or less than a yard?.

This short video and interactive assessment activity is designed to teach second graders about dividing lengths (english units).

This short video and interactive assessment activity is designed to teach fourth graders about dividing lengths (english units).

This short video and interactive assessment activity is designed to teach fourth graders about dividing weights (metric units).

This short video and interactive assessment activity is designed to teach fifth graders about division of lengths (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about estimating measure by image: centimeters or meters?.

This short video and interactive assessment activity is designed to teach fifth graders about estimating the measure of objects by image: feet or inches?.

This short video and interactive assessment activity is designed to teach fourth graders about estimating measure by description - multiple choice.

This lesson unit is intended to help teachers assess how well students can: Understand the concepts of length and area; use the concept of area in proving why two areas are or are not equal; and construct their own examples and counterexamples to help justify or refute conjectures.
