Fraction Memory
Standards: Math: 4.NF.1 Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using
visual fraction models, with attention to how the number and size of the parts differ even though the
two fractions themselves are the same size. Use this principle to recognize and generate equivalent
fractions.
Objectives: Students will match a fraction to the fraction it would be in simplest form in order to make
matches to win the game.
Assessment: Observe as students play the memory game.
Advanced Preparation: Create decks of cards with fractions in simplest form and a fraction that matches
each.
Lesson:
1. Review what it means to put a fraction into simplest form and common factor.
2. Go through some examples on putting fractions into simplest form. Use page 521-522 for
examples. Have students write the answers to each example of their dry-erase board or scrap
paper so they can show you their answer.
3. Pair up the students in the class. Each pair needs to a deck of cards.
4. Explain to the students that to get a match they must pair up a fraction with the fraction it
would be in simplest form. Allow students to have their dry-erase boards or scrap paper out
next to them so they can use it to get the fractions into simplest form so they know which
fraction they need to match.
