Trig

Student Created Trig Word Problem

repost from Make Math Not Suck

For the last 9 years, I’ve had students do a Trig project where they use handmade clinometers to measure the height of an object taller than they are. I love this project because it shows the application of Trig and guides students through a thought process to solve this type of problem.

This year I wanted to shake things up a bit. I wanted them to do the same project, but this time I wanted them to write an angle of elevation word problem. Students struggle with the word problems, and writing them helps them understand the process and required information.

As always, I was blown away by the creativity of some of my students. Their word problems were hilarious! They were problems I would WANT to solve. I took a few and used them on our assessment.

Since we had a recent ice storm, pictures had to be taken inside. It was Homecoming week, so we had some interesting backdrops. Students used the HOCO decorations and wrote their stories around them. Aren’t kids great?

Angle of depression is still giving us issues so maybe next year I’ll have them measure something below them. Maybe from the bleachers or the top of the steps. Hmm… food for thought!

Measuring height with Trig

I started to share this project with someone the other day and realized I had never written a blog post for it. We have used this project for quite some time and I love the digital aspect having students label their image and explain their process. We have the students make the clinometers but we give them little guidance as far as the project goes. We want them to problem solve and figure it out. We simply tell them to go measure something bigger than they are. I also limit their travel to school grounds (I did have a student go to the nearby gas station once. You have to be specific!!) I had a group of students last year that forgot their tape measure so they measured in shoe length (yes, I had a one-shoed student outside) and then converted that to inches when they came inside. I love the thought process behind their solution!

Not only does this give purpose to the study of trig, it also gets students outside and working together. It also helps students understand angle of elevation a little better with concrete examples.

I love the first one. She wrote a word problem for her image. Hmm… might have to steal that idea!!

I’ve included my clinometer document (I did steal the image from someone, sorry whoever you are!) and my scoring guide.
