In this online interactive worksheet, students determine the missing length of a geometric shape and then check their answers.

Eighth graders discover how to compute the perimeter, area, and volume of different objects. With partners, they find and calculate the perimeter , area, and volume of 10 items each and exchange information. Students compile their...

Young mathematicians work to recognize the relationship between their scale models of the Joides research vessel and the real vessel. They calculate the relationships between various parts of the ship using fractions, ratios, and...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Elementary schoolers are arranged in pairs and view the video Math Works: Measurement: The Difference Between Perimeter and Area. They discuss any prior knowledge they have of the term perimeter and then brainstorm together what the...

Elevate your fifth graders' understanding of math concepts with a series of vocabulary posters. Featuring terms concerning probability and statistics, measurement, algebra, and decimal place value (and many more), the posters are...

In this science worksheet, students identify and explain what each unit represents and how much each one equals. Then they use a metric ruler to locate each measurement and write it on the line. Students also locate the distance between...

High schoolers use similar triangles to find missing heights.  In this using similar triangles to find missing heights lesson, students use proportions to find the heights of missing side lengths.  High schoolers find the...

Learners measure and apply their knowledge of proportion to solve problems. In this geometry lesson, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects outside...

In this measurement worksheet, students write 4 questions that can be answered by making measurements. Students also use estimate the measurement for 4 given objects.

Young scholars use similar triangles and a sight tool to find the height and distance between large objects. In this similar triangles lesson plan, students use a constructed sight tool to measure the distance and height of an object...

Students use water filled pipes to play a tune and consider the mathematics behind the sound waves. In this sound wave activity, students play a tune with water filled pipes. They create a mathematical model to evaluate the wavelengths...

Students measure prisms and determine their volume. In this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...
