Using triangles to build strength
by Sadie Hale
Over break, many kids in Ms. Dehart’s Geometry classes built their masterpieces. This project was a straightforward and time-rewarding model bridge. Their task was simple. All they had to do was build a truss bridge out of popsicle sticks and make sure they included many congruent triangles with a key.
Ms. Dehart explains this project by saying, “In Unit 5, students in Geometry learned about the rules of triangle congruence, such as SAS, ASA, AAS, SSS, and HL. They showed their understanding through simple problems, algebraic problems, proofs, quizzes, and tests. The project was for students to apply their knowledge of triangle congruence by creating a truss bridge made up of congruent triangles.”
One of her students, Elayna Norman describes her take on the project, saying, “I thought it was a good idea to make math more fun but I didn't realize how challenging it would be to make my planned sketched into something real.”
Sophomore Sheridan Davis says, “I thought this project was a good way to teach us the different types of triangles. The assignment was a little tricky because the directions weren’t very clear. One thing that didn’t make sense was that you just had to say what type of triangle it is, but you aren’t able to tell just by looking at the bridge. But, overall this project was good for us to get familiar with the types of triangles.” Her classmate Madison Russell agrees, and adds, “I liked having a visual and hands on project to help me better understand this math unit. I liked having freedom to be able to build any design and paint any colors I wanted to!”
This project was due on Tuesday, November 27, and the students were assigned this creative project two weeks earlier.
Another one of Ms. Dehart’s students, Mackenzie Yeoman, describes what she would do differently by saying, “I would color my triangles before gluing them together because it was hard to color once the whole thing was put together.”
Ms. Dehart’s goal for her students was “for students to see how Geometry can be used in the real world through architecture and design.”
