The pessimist in me is scared out of my mind that my students will stop caring and the next 4 weeks will be hell – I can no longer motivate some of the more boring and rote procedures by simply saying ‘You don’t have to like it, but you have to know it if you want to graduate’. This has substantially changed the culture of my classroom in two ways. Personal Teaching Note: With the way things went this year, all the content from now to the end of the year is post high-stakes-big-deal-standardized-test (they took the big Arizona exit exam a week ago). Focus on equilateral triangles and secretly about cool shortest path problems. I recommend reading her blog post if you’re looking at this project I stole all the images of the dollars from her website – I hope she doesn’t mind.

Be sure to read my full disclosure note below.įull Disclosure: This project is a retooled version of how Kate Nowak teaches 30-60-90 right triangles – see her blog post here. Focus on equilateral triangles and secretly about conspiracy theories in the US Dollar. The instructions are embedded in the article along with several strategies students used to solve the problem) Origami Instructions (Actually, this is a link to an article from Mathematics Teaching in the Middle School published by NCTM. Focus on isosceles right triangles as well and secretly about how all squares are similar to each other

Origami Instructions (Found these online somewhere a long time ago, so not sure who to credit this to. Focus on isosceles right triangles and secretly get them thinking about infinite series… However, in a week when I get to trig ratios, we’ll revisit these and make a big deal about the angles. The way I’m teaching this unit, this section is all about finding patterns, so I’ve been emphasizing the patterns related to equilateral triangles rather than focusing on the technicalities of the 30-60-90 relationship. Quick Note: for now, I’m purposely avoiding classifying these by their angles (ie: 30-60-90), which is why the second worksheet is all about equilateral triangles.

Practice Problems: First better make sure they know how to do the basics… Some projects involve basic knowledge of volume and surface area. Also using these lengths to find areas of squares and equilateral triangles. Here they are in their raw form.Ĭontent Covered: Finding missing side lengths of isosceles right triangles (45-45-90) and equilateral triangles (which are composed of two 30-60-90 triangles). Over the weekend, I had several strokes of insight and put together 4 origami-based projects for my students.
