We are looking at geometry in math with a focus on what properties shapes have and how we can use those properties to describe, compare, and understand shapes. We started with an activity to see what we already know about quadrilaterals and triangles. It seems we know a lot about sides but need to learn some more about the angles. We also need to learn more about the specific kinds of triangles (grade 5) and quadrilaterals (grade 4).
Today we looked at some of the benchmark angles and took a look around our room for examples. In looking, we noticed that there are a lot of right angles in our room because our room is full of squares and rectangles. That got us thinking: if the triangle is such a strong shape, why do we have so many squares and rectangles in our building? Well, I asked a carpenter that happened to be in our room after school and I've got some data that we can talk about tomorrow.
Sorry for the orientation of these pictures! Bonus question: how many degrees would I have to turn these pictures to get them to face the right way?
What is happening in these pictures? Only the grade 4s will know. Ask them and see what they say!
