You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

What does it take to build a stable arch? Pupils apply vectors and physics as they examine arched bridges and their structural integrity. They use vectors to represent the forces acting on the stone sections and make conclusions based on...

Students discover the need for standard units of measurement. They be engaged in estimation, problem solving, and use of measurement tools to begin an understanding of the metric system.

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Third graders have a blast trying to measure live, wiggly, stretching worms to the nearest inch. Groups record their data onto a class graph and then compare characteristics. They share their findings with the rest of the class. Fun lesson!

Students discover the vocabulary used for distances in space and review measurement units and instruments before creating a scale model of the planets. They determine how to calculate the relative distances between the planets using a...

Students are given the task of designing an apartment. In groups, they practice estimating the area and perimeter of different shapes. After designing their space, they apply the same formulas to solving real-world story problems.

Learners, using wood blocks and model boats, investigate how the shape of an object affects friction it encounters as it is drawn through a towing tank.

Students time battery operated cars over a set track and determine the velocity of each type of car. They use the cars as manipulatives to demonstrate word problems involving velocity.

Students watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record their...

Fourth graders examine the Triangle Inequality Theorem by investigating possible lengths of the sides of a triangle.

Second graders measure surface area and perimeter using estimation. They complete a variety of measurement activities using Cheerios breakfast cereal.

Tenth graders identidy and define various geometry terms, Students create exact replicas of a shape that is either smaller or larger than the original shape. Students prove that their entire shapes are larger or smaller in the same...

Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.

Students discuss sound and how it's measured, and through experimentation and implementation of the scientific method, they determine the speed of sound.

Learners demonstrate visually Mankind's relative place on the earth's timeline. They familiarize themselves with the use of the metric system in measuring and producting a timeline.

Fifth graders work in teams of four to measure the rebound heights of a tennis ball dropped from four different heights. They investigate with the bouncing balls to measure changes in the type of energy they possess.

Second graders publish a class cookbook of their own recipes. They explore the nutritional value of foods, calculate the measurements, and prepare a healthy recipe for the class.

Students observ the cooling and warming of room temperature, hot, and ice cold cans of water by measuring the change in temperature over time. They then attempt to develop explanations for the observations made and apply their findings...

Third graders use estimation, fractions and decimals to determine the perimeter of objects in the classroom. They are given a worksheet with a list of the items on it. The worksheet has columns beside each of the items for estimation and...

Students convert measurements within the metric system. For this measurement lesson, students explore the different units of the metric system and practice converting numbers from one unit to another.

Students estimate quantity, length, and area. Students practice making comparison estimations of different items and estimate whether or not the amount is greater or less than a certain amount. Students practice making estimations.

Students observe the movement of pendulums, they begin to understand the relationship between gravitational forces and the mass of objects, the changes in speed and direction of objects, and the distance between objects. They understand...
