Young mathematicians will enjoy demonstrating their skills with this lesson on finding area. It addresses the concepts of length, width, and square units.

Introduce your students to area and teach them to use the formula Area = Length x Width within the context of real world problems.

You need the length and the width to find the area of a rectangle or square, but what if one piece of information is missing? Use this lesson alongside What's My Area? or on its own.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Students will learn to convert metric units by applying concepts in word problems. Exercises and worksheets incorporate length (meters), and optional practice offers more instructions on mass (grams) and volume (liters).

Help your students learn how long a minute is with this lesson that shows them how the length of a minute can appear to change depending on the activity, all while putting their time estimation skills to the test.

Are your students having trouble taming run-on sentences into a more manageable length? In this lesson, your students will learn to not only recognize a run-on sentence, but also how to stop it in its tracks.

Students will solve area problems by multiplying side lengths for rectangular shapes in real world contexts.

In this hands-on lesson, your students will get to sharpen their measuring skills as they measure lengths of items in your classroom to the nearest quarter inch. They'll get to then use their data to create line plots.

Teach your students to use an area model to solve multiplication problems with a two-digit factor.

Let your students decorate their own room with this lesson that has them use area to place furniture in a room.

Teach your students to find the perimeter of polygons using real world examples. They will make polygon pictures using tangrams and practice finding the perimeters of the polygons in their masterpieces.

Looking for a fun way to reinforce multiplication and area finding skills? This hands-on lesson gives students a chance to create their own multiplication equations by making rectangular models.

Make real world connections with your students when it comes to perimeter. Use this geometry lesson with your students to discuss real contexts and teach them how to calculate perimeter.

A hands-on approach makes geometry fun! Use this lesson to teach your students about the basics of perimeter with geoboards.

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.

This lesson on perimeter will let your students walk around the class to see the border, use a measuring tape to measure the walls in their classroom, and enable them to understand how math is related to real life!

Get your students comfortable discussing their math thinking in converting centimeters to meters. This lesson may be used on its own or as support to the lesson Converting Metric Measurements to Decimals & Fractions.

Support your students as they collect, organize, and discuss measurement data! Use this lesson independently or alongside Making Measurements for Line Plots.

How much longer is a blue whale than an orca? Teach your students to use bar models and number sentences with variables as they solve these wild word problems!

Support your students' comprehension of perimeter word problems by teaching them to use an engaging strategy and graphic organizer. This lesson can stand alone or be used as a pre-lesson for Polygon Perimeters with Tantalizing Tangrams!
