Triangle Designs - Enrichment 16.5

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson connects geometry, earth science, and delicious snacks to teach kids about ecosystems...

Scale up your lessons on geometry and ask learners to investigate conditions on triangles, scale drawings, area and circumference of circles, and angle relationships. The resource includes activities and a homework assignment.

Try five problems on triangles. Levels A and B focus on shapes that can be created from right triangles. Level C touches upon the relationship between the area of a six-pointed star and the area of each triangle of which it is composed....

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

After reading a brief overview of automobile history and introduction to energy and motion, automotive engineering teams plan, construct, test, and evaluate a rubber-band-powered car. This manipulative experience can enrich understanding...

How many isosceles triangles can you create on a seven-by-seven peg board? This is the task scholars attack in their collaborative groups. The problem prompts discussion on distance, slope, and the definition of isosceles triangles.

After reviewing characteristics of seven types of triangles, young geometers discover how to find the missing angle of a triangle. Then, they practice identifying triangles, find missing angles, and find missing side lengths of similar...

Use the height of an acute triangle to create two right triangles. The third lesson in a series of 22 has pupils divide acute triangles into two right triangles. Scholars calculate the areas of the two right triangles and add them...

Using a cut-out template of a whirligig, emerging engineers experiment with flight behavior. After you teach them the concepts of force, air resistance, and lift, they discuss what variables on the whirligigs might be changed in order to...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy Triangle,...
