During our decimals unit (and after our fractions unit), I gave my 5th graders this fun activity. It allows them to practice turning fractions into decimals into percents by:
1) simplifying fractions to "easy" fractions (like 3/4),
2) making the fraction out of 100
3) dividing the numerator by the denominator
This was a great activity because it challenged the kids, provided a fun activity, and gave them great fraction, decimal, and even statistics practice! The kids loved doing this!
