Snowflakes are actually very mathematical!
So, today we completed our notes on the geometric shapes found in a hexagon. We are working with critical attributes of each shape to create our definitions. We ask questions like:
- Is a hexagon a polygon? How do you know?
- How many sides? (4 sides is also called?) Congruent?
- How many vertices?
- How many angles? What kinds of angles? Congruent?
- Is it a parallelogram? How do you know?
- What type of lines make up the shape? (Intersecting or Perpendicular) How do you know?
- Are there any lines of symmetry? How many?
We completed this task using a hexagon (yesterday), then we folded the hexagon in half creating a trapezoid, next, we used the trapezoid to create a rhombus, and finally we used the rhombus to create a triangle (an acute equilateral triangle to be exact).
I was glad that I made students name the types of lines because they always wanted to call them perpendicular. This allowed me to reiterate exactly what makes lines either intersecting or perpendicular. I also had to correct the terminology of diamond. A rhombus is not a diamond! And finally, it was fun to have them correctly label the triangle as we had been working on that in our Fifth Grade Builders.
This activity did not take too much time. I had planned it that way on purpose. I wanted to have class time available for our assignment and even time to get back onto Think Through Math.
We began using a Countdown to STAAR today. We will alternate between the Fifth Grade Builders and the Countdown to STAAR. Countdown incorporates word problems, Builders does not. However, both will help me close gaps. I love having work completed in class AND students must show me their work/answers after solving each problem. This allows me to correct and reteach in real time. Love it!
