Activity Summary: In this activity, students will participate in a memory game to practice the skills of multiplying and dividing fractions.
Subject:
Math: Numbers and Operations
Grade Level:
Target Grade: 7
Upper Bound: 8
Lower Bound: 6
Time Required: 20-30 minutes
Materials:
One set of 16 HYPERLINK "Memory.doc" memory game cards for each pair (or group) of students
Activity Plan:
The students are in grouped in pairs and each pair gets one of the two sets of cards, which have been cut up into 16 cards for each set.
The students mix cards up and turn all of them face down on the desk. The first student turns a card over and calculates the fraction on the card by multiplying or dividing. Then the same student turns over another card and calculates. If the answers match, that same student takes the pair and gets to go again, if not, then the other student tries.
Play continues until all cards have been matched up. If there is time, the students can switch sets with another group to get the other set and play the game with those cards. The answer key is given below, the numbers correspond to the numbers in the upper left corner of the card.

Prerequisites for this Activity: (Optional)
Students should be familiar with the processes of multiplying fractions by multiplying numerators and denominators and dividing fractions by multiplying by the reciprocal.
Troubleshooting Tips:
The students may have a bit of trouble remembering where each fraction is, since they have to do some work to get the fraction each time, so allowing them to write down the answer for each card after they calculate it will allow them to not have to do the calculation each time and will help to speed the game along. Or, instead of having the students match two expressions of multiplication or division, the teacher could edit the cards to have one card in each pair be the expression to evaluate and one be just the reduced fraction. This will also reduce some of the frustration for the students and speed the game along.
TEKS:
7.2 (A) Represent multiplication and division with fractions and decimals
7.2 (B) Add, subtract, multiply, and divide fractions and decimals to find answers
