Area of Triangles Foldable Reference Activity with Formula Options

This Area of a Triangle activity uses silly - but memorable and relevant - phrasing to teach students the relationship between triangles and rectangles - they'll remember this activity. Several different formula options are available - choose the one that you use to teach.

Sometimes it’s the silly things that help keep ideas sharp and memorable.

This foldable reference activity - perfect for student interactive notebooks - represents a funny “love triangle” because half #1 of the triangle is looking for his/her other half. The remaining #2 half says, “You complete me!” because when they combine, they make a complete rectangle. Simple, but memorable! 

In my district, depending on the grade level and depending on the students, we switch from using the formula A=length x width to Area = base x height. The third option of Area = 1/2 base x height is also included. Choose the option that suits the needs of your class!

What you receive:

There are 6 sets of foldable styles. They’re all similar except for minor details. Choose the option that best suits your needs.

• Set 1 – Full-sized foldable activity designed to fill out an 8½ x 10-inch paper. It uses the formula Area = base x height. I hole-punch the side of the first page, and students put it in their binders. Colored paper, markers, & crayons make it look fantastic!

• Set 2 – Small-sized foldable activity – perfect for the smaller sized composition notebooks that many people use for Interactive Student Notebooks. This set uses the formula Area = base x height.

• Set 3 – Full-sized foldable activity – uses the formula Area = length x width.

• Set 4 – Small-sized foldable activity – same as set 3, but smaller. It uses the formula Area = length x width.

• Set 5 - Full-sized foldable activity using the formula Area = 1/2 base x height.

• Set 6 - Small-sized foldable activity - same as set 5, but smaller. It uses the formula Area = 1/2 base x height.
