Aim:
Students will be able to describe parts of a fraction and make equivalent
fractions .
Specific Objective(s):
o To view parts of a fraction.
o To make equivalent fractions.
o To reduce a fraction to lowest terms .
Materials/Supplies:
o Paper and pencil
o Colored pencils
o Fraction Fairway game sheet
Lesson:
o Introduce with “pizza story” using parts cut and parts eaten.
o Review parts of a fraction and what each means.
o Draw
on board. What fraction is this?
Continue to add more lines to create equivalent fractions. What do you notice
about how the numerators and denominators are changing ?
o Give more fractions for students to make equivalent fractions on their own.
Students share their methods.
o Make list of methods used (paper folding, draw picture , skip counting,
multiplying numerator and denominator by same number).
o Review reducing fractions to lowest terms, relating this to equivalent
fraction activity above.
o Play Fraction Fairway (page 2). Decide on a fraction for each hole (either 9
or 18). Roll 2 dice until an equivalent fraction is rolled. The number of rolls
needed is the score for the hole. At the end of the round, total up the score.
o Closure/discussion
- What did you discover about equilateral fractions?
- What are some ways to make equivalent fractions?
- Return to original pizza story?
