Triangle Sum - A Sneak Peek
Many students who love Geometry share their disappointment with me upon finding WHAT?! Algebra in their Geometry class?!
What can we expect in a da Math Shop? Follow along in the videos below to get a sense of how Geometer's Sketchpad and da Math expertise combine to form a dynamic investigation.
In-person da Math Shops feature students exploring on their own computers, producing their own dynamic experiences.
1 -What's in a conjecture?
We need lots of measurements to make an educated guess. But, how can we model all the triangles in the world?!
3 - Hands On learning
Before continuing with our dynamic sketches, let's test the conjecture with a real-life triangle made out of paper.
5- What's in a line?
Rotations are transformations that maintain the size and shape of our original triangle. But, what's the POINT?
2- Measuring Angles
Math is a universal language and as naming angles before measuring them is an important part of the process.
Let's rotate our triangles to explore how our conjecture may be true.
6-Algebra in your geometry?
We see how an applicable algebra problem integrates with the investigation as well as a multiple choice question.
