Picturing Polygons

For the next few weeks, our class will be working on a unit called Picturing Polygons. In this unit, we will work with important mathematical ideas about two-dimensional objects by exploring polygons and coordinate geometry. As the unit unfolds, your child will work with:
* polygons with different numbers of sides (up to 10)
* triangles and quadrilaterals whose angles and sides follow certain rules
* regular polygons
* similar polygons (of different sizes, but same shape)
Look for opportunities to talk about polygons with your child. Most of the angles in our rooms and on our furniture are right angles (90 degree angles). Why is this? A diagonal across a square forms a 45 degree angle. Why? If your child has any game boards or spinners, look at their designs. Do you see any of these angles? What other angles do you see?
Above all, have fun creating and discussing shapes and enjoy watching the growth of your child's understanding of geometry.
