This resource will help assess your students' mastery of concepts surrounding measurement and time. This worksheet will challenge your third graders with problems on area, perimeter, measurement, and elapsed time problems.
Students will use the inverse relationship between multiplication and division to complete an area formula in a real-world situation. Use this lesson on its own or as support for the lesson The Case of the Missing Rectangle Side.
Your students will become junior math detectives as they hunt down the missing side of a rectangle by applying the area formula for rectangles. The only clues they have are the rectangle's area and the measure of one side.
Area models are building blocks to more complicated multiplication and division. Use this lesson to refresh students on the relationship between multiplication and area to prepare them to use the area models strategy with larger numbers.
