Fun With Fractions to Percent Math

The girls had fun memorizing common fraction and percent equivalents with this fun sock-toss game. Percent cards were taped to the wall. Then I called out a fraction, and they had to throw the rolled up sock and try to hit the correct percent card.
Before doing this game, we learned a song I created to help memorize these equivalents. The song is included below. Then I gave the girls a set of yellow and pink cards on which they wrote the fractions on one color and the percent and decimal on the other color. Then I had them spread them on the floor and then when I said, "Go!" they raced to see how fast they could match them up. Then we played the sock toss game on the wall. Here are the equivalents we used in the song and game.
1/2 = 50%
1/3 = 33 1/3% (or 33.3%)
2/3 = 66 2/3% (or 66.6%)
1/8 = 12 1/2% (or 12.5%)
1/5 = 20%
2/5 = 40%
3/5 = 60%
4/5 = 80%
1/4 = 25%
3/4 = 75%
3/8 = 37 1/2% (or 37.5%)
5/8 = 62 1/2% (or 62.5%)
7/8 = 87 1/2% (or 87.5%)
If these equivalents are memorized, it will really save time in a test like the ACT or other standardized testing. Here is the song we used. Please feel free to use it for your own homeschool.
