Ways to Use Fraction Circles to teach Fraction Concepts

1. Ways to Use Fraction Circles to teachFraction Concepts One example is provided for each concept to show you ideas to use with your class

2. Teacher Note: Naming fractions; showing how equal parts make a whole Build a pink circle. pink + pink = 2 pink or 1 + = You built one whole circle. + = 1

3. Teacher Note: Adding with like denominators Use two orange pieces to build part of a circle. orange + orange = 2 orange + = You built a fraction or part of a circle. + =

4. Teacher Note: Adding with unlike denominators Use one pink piece and one orange piece to build a portion of a circle. pink + orange = pink and orange You built a fraction or part of a circle. To know what fraction of the circle we built, we need to do a little more work.

5. Teacher Note: Adding with unlike denominators cont. First, let’s identify the value of each piece. 1 orange 1 pink + = pink and orange = + ? To better understand what fraction of the circle we have built, let’s think in terms in one color.

6. Teacher Note: Adding with unlike denominators cont. pink and orange Can you use one color to perfectly cover the pink and orange pieces? Now let’s use this information to figure out what fraction of a circle is created with one pink piece and one orange piece.

7. Teacher Note: Adding with unlike denominators cont. 1 orange = 2 teal 1 pink = 3 teal 1/3 = 2/6 1/2 = 3/6 1 pink + 1 orange = 5 teal + = + = BECAUSE
