To play Weigh the Wangdoodles, find the weight of each Wangdoodle using the information provided by the scales.

Make sure that the weight you assign to each Wangdoodle works on each scale.

Think about ways to test out different weights. If the red Wangdoodle weighs 16, what would the green Wangdoodle weigh? What is the red Wangdoodle weighs 17?

KENKEN is great for problem solving and practicing basic computation. KENKEN puzzles can be as challenging as you want them to be. They are similar to Sudoku, but incorporate more math. Follow the instructions on the KENKEN website, choose the size of your puzzle (a 3x3 square, 4x4 square, 5x5 square, etc.) and start playing!

Drag the corners of the colored boxes in Design a Party to adjust the size (area + perimeter) of each party area. Make certain that they fit the specifications given! For example, the ice cream bar needs to have an area of 18 sq ft and a perimeter of 18 sq feet, as well.

Hungry Puppies, from Arcademics.com, is a multi-player game that allows students from anywhere in the world to compete against one another while practicing adding decimals!

Puppy Chase, another game from Arcademics, is a multi-player game that allows students from anywhere in the world to compete aginst one another while practicing fraction --> decimal conversion.

Great for fact practice! Arcademics Skill Builders has games to practice different skills: addition, subtraction, multiplication and division facts, as well as some basic algebra and telling time. Students are able to play against a computer or other players in real time. A few of the games are spotlighted below.

While not quite a 'game,' the Thinking Blocks online math modeling tool promotes mathematical reasoning as students solve problems. The site helps students break down problems into easier chunks. See a sample addition problem that has been partially completed below.

Equivalent Fractions BINGO is a fun educational game for children to practice equivalent fractions. The game has two modes: Easy & Challenge.

Go for a challenge! Easy mode of play displays a pie graphic to represent the fraction. Challenge mode displays only the numerical fraction at first. If the student needs help it will introduce more visual representations.

Challenge points are awarded based on how much help the student needed to correctly answer the question. Less help = more points!
