Let's get started with our next math unit, Geometry! Students will be learning about concepts of 2-D and 3-D shapes, symmetry, angles, and how to use a protractor. If you have a protractor at home, you could send that in with your child to use in class.
Students will need to know how to identify and measure angles. Focusing on the 3 different types of angles at home would be appreciated.
Check out this YouTube video to understand the 3 different types of angles (it's a song)

These angles are:
a) acute angle= less than 90 degrees e.g. pliers, scissors, flip cellphone, stapler remover

b) right angle= 90 degrees e.g. a square, a rectangle, tiles on the ground, tiles on a backsplash, a cover of a book, a remote control
c) obtuse angle= greater than 90 degrees e.g. scissors, hands on a clock, legs on a spider, tree branches
Ask your child to be an "angle detective". See how many different types of angles they can find at home and have him/her explain to you why it is an acute, right, or obtuse angle. They can write or draw these examples and then bring them to class to be displayed on our math bulletin board and to share with the class.
