Grade 5 Math Web Sites


NameThat Portion


This site is loaded with games that will help students understandthe ordering of fractions, decimals, and percents. Go to the Numbersbox and the games will be there. Perplexing Percentages (Discounts onclothing), Majority Vote (percentages), and Grape Juice Jungles(ratio and proportions) are good.


This site is pure practice. You put in a fraction, hit return, andthe decimal appears. Conversely, you put in a decimal, hit return,and the fraction appears,


This game is interesting once you get the hang of it. Students aregiven empty squares and asked to create the fraction listed near thesquare. They can do this by clicking on + or &endash; Rows to createportions. After matching the squares, they are asked to createanother square that is between those two. A nice feature of this gameis that it is self checking.

Numberand Operation Concepts

There are plenty of activities on this page that build on eachother. Fraction Four is a great game because it involves two players.You can regulate the time and what topic you'd like.
