We have begun a Math unit on Transformational Geometry. We are discussing how to move a figure on a page. We know that the figure and it's image needs to be congruent. Ask your child what congruent means! Yesterday we began talking about translations (slides). Today we discuss reflections (flips). Then we will move on to rotations (turns). We will discuss symmetry and figures with multiple lines of symmetry. Students are encouraged to use lots of math language in their explanations. Look around the environment to see examples of these concepts! Here are some of the words we will be using during this unit:
- grid
- coordinates
- figure
- image
- congruent
- transformations
- translation
- reflection
- rotation
- symmetry
