What's it about?

Sumdog has 25 free math practice games customized to your child's ability level. Guided by a cute orange dog, you'll explore a town filled with activities such as Talent Show, Submarine, and Alien Invasion. Click the images and you go to the games, which cover arithmetic, fractions, decimals, percentages, equations, and money. When you get a correct answer, you get a coin, which you can spend on costumes and the like for your avatar. Activities adapt and continue to challenge as you build skills in each subject.

Is it any good?


Kids love choice and competition, and Sumdog provides both as well as real math practice. Each game is timed, creating a sense of urgency and excitement and helping kids build speed and increase math-fact fluency. Kids will love the incentive to earn coins to shop for their avatars, although some of the female clothing options are provocative. Some games are a bit much, such as Touchdown: dizzying graphics may prevent kids from focusing on math. However, Sumdog provides a bunch of types of games, which addresses various learning styles.

Families can talk about...

  • Families can talk about ways math is useful in everyday life.  How do we use it in home-improvement projects?
  • Families can talk to their local school districts about entering one of the Sumdog math competitions.

  • For families interested in other math competitions, see if you have a local Math Olympiad team.

sumdog is ok

i think sumdog is GREAT but there is one issue that is when you play really hard and get lots of correct answers you get 0 coins which makes you upset that's happened lots of times to me and most of my classmates
