Students will practice calculating volume as an additive property by making mock hamster mansions from boxes. Groups will calculate the volume of living space that they designed for their hamster in cm³ and document their work.

Challenge students to convert measurements between their metric counterparts! Students will relate the measurements to real-world objects. Use this lesson as support for the Converting Metric Measurements in Word Problems lesson.

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.

In this teacher-approved lesson, students will make and play with oobleck (corn starch and water), then write about their experiments. Young scientists will have a blast seeing their oobleck mixtures seemingly come to life.

This experiment is a fun lesson that captures the ears, eyes, and minds of students! It combines writing, reasoning, predictions, and teamwork with candies and soda to produce a memorable lesson on chemical reactions and energy.

Let your students learn how to find the area of rectangular objects by doing hands-on activities. Your students will love finding the area of various rectangular objects around the classroom!

Students will become more familiar with common metric measurements by matching everyday objects with the metric mass and volume units they would use to measure them.

Use this vocabulary-focused lesson to teach your students about area. It can stand alone or be used as a pre-lesson for Finding the Area of a Rectangle.

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.

Challenge students to think about decimals while identifying numbers to the hundredths and thousandths. They'll discuss decimal attributes too. Use this lesson on its own or as support to the lesson Dividing Decimals: Estimation.

Collect and graph! In this lesson, your students will practice collecting, organizing, and interpreting data by using real life examples.

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.

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!

Use this support lesson to provide students with the opportunity to explore what it means to estimate. This hands on activity can be used alone or alongside the lesson Estimating Length.

Support your students as they utilize key academy language to speak about visual and numerical representations of fractions. Use this as a stand alone lesson or as a pre-lesson for Fractions in Action.

Help your students learn the standard measures of length and foster critical thinking with this engaging lesson. Use alongside The Smaller They Come or as a stand-alone activity.

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