Practice Geometry! Get the Right Angle

Identifying angles as vertical, adjacent, complementary, or supplementary may sound intimidating, but with this exercise, you can turn your child into an expert angler in no time!

What You Need:

math book or dictionary

index cards

pen or pencil

What You Do:

Step 1
Have your child look up the definition for each term in a math book or dictionary and write them on flash cards. On one side, write the name, i.e. “Vertical Angle,” and on the other side, write the definition and draw a correct sample angle – the visual will help him remember.

Step 2
Tackle the terms one at a time. For example, start with adjacent angles.

First review the flash card.
Next have your child draw an example on a separate sheet of paper.
Check to make sure it’s correct. Then have him explain to you why it’s a set of adjacent angles. Repeat with two or three different examples.
At the bottom of the page, have him write the explanation in his own words, the way he’s been explaining it to you.

Do this for each term. It’s important to have him create his own angles first; children learn best by doing!

Step 3
Either find in the book or create yourself a set of examples of just one type of angle. Have your child look at the set and tell you which type of angle it is. Then have him explain to you how he knew. Have him identify similarities between the angles. This solidifies a set of rules or generalities in his head, which will help him retain the information. Repeat for all types of angles.
