How it works
Percent bingo with 48 percents on the cards, from 1% to 300%, each called by the fraction or the decimal equal to it. 5% and 50% can share a card, so pupils have to tell 0.05 from 0.5.

Call the fraction or the decimal
Each call shows a percent with its fraction in lowest terms and its decimal: 35% comes with 7/20 and 0.35. Read one of the two aloud and keep the percent to yourself. When a pupil calls bingo, have them give the form you did not read for each covered square.
From 1% to 300%
Twelve squares are benchmarks such as 25%, 50% and 80%. Around them sit the twentieths from 5% to 95%, eight more under 10%, eight twenty-fifths such as 12% and 64%, the four eighths from 12.5% to 87.5%, and eight over 100%, where 150% is called as 1 1/2 or 1.5.
- 33 1/3% and 66 2/3% are left out: their decimals never end, so the only call would be the fraction.
Questions and answers
How do you play percent bingo?
You call and pupils convert. Read 1/4 or 0.25 from the caller, and anyone whose card shows 25% covers it. A card has 24 percents round a free center; the first full row, column or diagonal wins.
What is 3/8 as a percent?
37.5%. Divide 3 by 8 to get 0.375, then move the decimal point two places to the right. The other eighths on the cards work the same way: 1/8 is 12.5%, 5/8 is 62.5% and 7/8 is 87.5%.
Can a percent be more than 100?
Yes. A percent is a rate per 100, so 150% means 150 for every 100: one and a half times the whole. Eight squares here are over 100%, from 110% to 300%.
What grade is percent bingo for?
Grade 6 and up. Common Core lists finding a percent of a quantity as a rate per 100 among its grade 6 standards (6.RP.A.3c).
