You're safe, when calculating the odds of stealing second base! Learners compare the rate of a runner to the distance the ball travels, in a lesson that explores right triangles and measurement. Full of discussion questions and fun...

A fabulous lesson on identifying circles, triangles, squares, and rectangles awaits your students. They use large motor skills hopping from shape to shape, use visual and kinesthetic skills passing a ball of yarn between three people to...

Trying to figure out the perimeter of a geometric figure? Here are a few word problems to set up algebraic equations to solve for perimeter. There are also some word problems to set up algebraic equations to solve for angles in a...

Middle and high schoolers use the Pythagorean Theorem to determine the length of the sides of a right triangle. They solve distance problems. This one-page worksheet contains 10 multiple-choice problems. This is self-checking worksheet.

Middle and high schoolers explore the properties of similar triangles. In this geometry lesson, pupils play a similarity basketball game, sketch similar triangles, and find the missing measures of similar figures. They find the height of...

Fifth graders build increasingly larger squares and triangles using pattern blocks. They record the growth patterns on a chart and look for corresponding numerical patterns. Students describe the patterns they find and use them to...

Combine printing practice, shape recognition, and the color red with your kindergartners. They start by tracing the word red and writing it once or twice on their own. Then, they examine an image of flowers and color all the...

Learners use a ruler to make measurements, and to create triangles and a rectangle. They take the shapes they've made and assemble them into an evergreen tree image. This simple, yet effective, instructional activity would be ideal for...

As a review of geometric shapes, such as circles, triangles, and squares, this resource would be a terrific addition to a classroom lesson. The visuals are inviting and the number of sides to each figure are also identified. In addition,...

What a fun activity for younger learners! Using this resource, they can discuss the attributes of squares, rectangles, triangles, circles, and ovals, and also engage in a motivating activity. For those learning about simple shapes, this...

Students draw triangles. In this shapes lesson, students discuss what they already know about triangles, what they are and what they are made up of. Students discuss the types of triangles and practice drawing each type.

Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...

In this area worksheet, students find the area of a triangle given the height and the base. They also find the height or base given the area of the triangle. 

In this triangles practice worksheet, students respond to 4 questions that require them to identify the pictured triangles as acute, right, or obtuse triangles.

In this word recognition activity, learners trace the word "triangle", write the word independently, and color the picture of the triangle.

In this unknown angle worksheet, students find the unknown angle in the triangle that gives them 2 angles. Students find 9 unknown angles.

Students use web applet to create congruent triangles. In this geometry lesson, students differentiate between congruent and similar. They create shapes online and drag those shapes around to create visuals of triangles.

Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

Learners follow detailed directions to create triangles on their graphing calculator. In this properties of triangles lesson, they will create triangles on their calculators using the Cabri Jr. application. They then identify three...

Learners investigate the special properties of an altitude, a median, and an angle bisector and explore how these special segments divide the area of a triangle. The dynamic nature of Cabri Jr. allows pupils to form and verify conjectures.

Pupils examine the centroid of a triangle as they use Cabri Jr. to construct a triangle and its medians. The dynamic nature of the software allows learners to measure the lengths of the segments in the triangle and conjecture and verify...
