How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Use a right method to find a distance. Given a right triangle, class members find the length of one side given the measurement of the other two sides—the missing side may or may not be the hypotenuse. A video reminds the pupils how to...

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

Creating a triangles is as easy as 5, 6, 7. Using a ruler and compass to measure off lengths, a short video shows how to construct a triangle with three specific side lengths. The example creates a triangle with side lengths of 5 cm, 6...

Use a West African folktale to practice several different skills in your first grade classroom. Learners read The Clever Monkey Rides Again and focus on rhyming words, reading comprehension, measurement, art, movement, and word...

Observe the change in the trigonometric ratios as angles vary. An interactive provides the values of trigonometric ratios for both acute angles in a right triangle. Pupils create a right triangle to match given criteria and find the...

Get creative juices flowing when you allow groups to figure out a procedure for how to find the area of squares and rectangles. They may use the individual patchwork blocks, or they may design one using the Design Template.

Examine the segment addition postulate through an online simulation activity. An interactive lesson allows scholars to manipulate points and watch as the lengths of segments change. Through their study, they are able to apply the Segment...

Assess how long the class pet snake grew and how long it was when it started growing with a short learning exercise. Learners use addition and subtraction strategies with measurements to answer three questions.

Mark off the length of the radius around the circle. Using a compass, the presenter shows how to construct a regular hexagon in a circle. Pupils see how triangles formed in the hexagon are equilateral, allowing for the construction to...

A n incredibly thorough worksheet on how to read and use a ruler awaits yours students. Students identify lines on the ruler and use the proper abbreviations for the lengths. Students answer ten questions about ruler usage.

Fourth graders explore the mass and length of peanuts by pretending to parent a peanut. In this mode, median and range lesson students graph their measurements and then use them to find the mode, median and range. Students discuss peanut...

Measurement and map skills are the focus of this instructional activity, where young scholars crawl through a "cave" made out of boxes, desks and chairs, observing the dimensions.  Your young geographers measure various aspects of...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 

Students examine the painting "Old Man With A Gold Chain" by Rembrandt. They identify geometric shapes in the painting, measure these shapes and compare the relationships of these measurements.

Ocean explorers or mathematicians research the wreck of the CSS H.L. Hunley. They investigate the actual dimensions of the Hunley using math and measuring skills. Afterward, they sketch a large scale drawing of the submarine outdoors on...
