In this length activity, students study the two objects in the 9 sets of problems and circle the object with the longest side. Students enhance their understanding of length.

In this estimation of length worksheet, 7th graders complete 20 different problems that include the estimation of numbers. They determine the approximate weight of each illustration shown in the box. Then, students circle the correct...

First graders use rulers to measure in both standard notation and centimeters. In this measuring lesson plan, 1st graders discuss the importance of a measuring standard. Students measure in inches and centimeters. Students compare inches...

In this metric conversion worksheet, students convert smaller units of length to a greater unit of length. There are nine questions to complete with available space to show work.

In this triangles worksheet, 10th graders solve and complete 10 different problems that include applying the Triangle Inequality Theorem. First, they use the illustrated triangles and the data table to test the theorem. Then, students...

You'd be surprised what you can do with a string! The constraint is the length of string, and the task is to maximize area. Given a series of composite shapes, learners must create a formula for the maximum area for a specified...

Why are right triangles so special? Pupils begin their study of right triangles by examining similar right triangles. Verifying through proofs, scholars recognize the three similar right triangles formed by drawing the altitude. Once...

Something for young mathematicians to remember: the sum of any two sides must be greater than the third. Class members investigates the Triangle Inequality Theorem to find the relationship between the sides of a triangle. At the...

What can symmetry tell us about triangles? After looking at four examples, learners will come to realize that lines of symmetry are different for equilateral, isosceles, and scalene triangles. Use this guided practice activity as an...

Get your youngsters using rules! For this challenge, they measure the shapes that make up a house and a tree to practice measuring in centimeters. Then, they write down the equation for each shape. (Example: 4+6+4+6.) Finally, they...

Here is an engaging lesson which invites learners to cut a strip of adding machine tape that is their height. They decorate their strip, arrange the strips from shortest to longest, and then discuss predictions.

All aspects of the path of light are included in a great summary. Internal reflection and the angles of paths in different materials are explained and the behavior of visible light through lenses and the effect on focal points are...

Amaze your classes with the ability to find side lengths of triangles immediately — they'll all want to know your trick! Learners use the Pythagorean Theorem and special right triangle relationships to find missing side lengths.

How much material is in a bead? Class members utilize volume formulas to determine the amount of material in a bead. The goal of the assessment is to show that the amount of material left in a bead is the same for all beads with a...

High schoolers measure various dimensions of a male and a female dolls body and scale them proportionally to average human measurements. They calculate the appropriate scale factor (magnitude) to enlarge their doll and apply that scale...

Students examine gravity, mass, and friction. In this speed and motion instructional activity, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.

In a cross-curricular measurement and literacy lesson, your class will identify and compare cooking measurement instruments. They read a recipe and sequence a set of similar instructions in which the steps have been mixed up....

Each member of the class creates their own paper ruler. Using their ruler, kids walk around the room measuring the objects you've specified. Discuss how items should be measured to the 16th of an inch, the smallest unit on their ruler....

Finding the volume of a right rectangular prism is the focus of the resource.  Worksheet includes a drawing of a cube to help learners visualize the concept. Young geometers will learn that as the side length increases, so does the...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

Young mathematicians compare the growth of two snake lengths in feet over one year in a straightforward word-problem task.

Young mathematicians demonstrate what they know about measurement with a four-task assessment that focuses on estimation, length, and inches.

Gotta catch them all—no learner left behind! Young scholars must predict the length of time it takes a phone attached to a fan to travel five kilometers given the radius and rotations versus time data. Why would you attach a phone to a...

No fair! I had to run more than they did! Young mathematicians first measure various lengths on a school track. They develop strategies and show calculations to prove that all participants will run the same length using a staggered...
