Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

Young mathematicians draw, create, and describe different shapes using triangles. They discuss attributes of the original and created shapes. Pupils classify the created shapes and draw and write in mathematics journals to communicate...

Learners explore the solar system. In this planets lesson, students learn about the other planets in the solar system. They watch a video clip from National Geographic on the solar system, compare and contrast the planets and create a...

Students participate in an experiment to discover the properties of lift. They work together to complete calculations and collect data. They share their results with the class.

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Practice estimating the angle by sliding the blue "X" button up and down to open and close the angle. See how many aliens you can zap with the correct answer. Your total correct out of 10 is listed just below the problem.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students are asked to match a given angle measure with one in a drawing. Includes video demonstrating a sample problem [2:14] and a set of...

This geometry resource investigates types of angles. Definitions, detailed examples, and practice problems are included.

In this interactive website, students practice various math skills such as identifying different types of angles, use the degree symbol, estimate and measure angles, and construct angles.

Use an angle wheel to make estimates of the measures of various angles. Printable instructional activity.

For this task, students use a piece of string or another tool to measure the radius of the circle and then mark off the corresponding arc length on the unit circle as many times as they need to for 0, 1, 2, 3, 4, 5, and 6 radians. They...

Conversion calculators galore! Convert just about anything from one measureable unit into another measureable unit here with over two dozen calculators. Each of the links is specific to a measureable quantity. Some examples include...

What angles can you see in these photos of Olympic sports? Can you estimate them? This challenging activity is aimed at older primary pupils at Key Stage 2.

Students learn about trigonometry, geometry and measurements while participating in a hands-on interaction with LEGO MINDSTORMS NXT technology. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the...
