Sumdog helps improve accuracy

Susanna Dayton, a teacher at Mariposa Elementary in St. Lucie, Florida, wrote to us last week about her experience with Sumdog.


Here’s what she had to say:

I just wanted to let you know how much our students enjoy the games on Sumdog. 

We have a student who was really struggling with math and his achievement was well below grade level. I set him up with a Sumdog account and encouraged his parents to allow him to use it at home. The first night he answered more than 900 questions with a 50% accuracy rate. The next week, his accuracy rate had improved to 55%. Three weeks later, he had answered nearly 4,000 questions and his accuracy rate had skyrocketed to 78%!

Thank you Sumdog for creating engaging math games that students love to play!

Festive avatar outfits!


Our biggest ever mathematics contest starts on December 6.

Every student who plays in the contest will receive three - yes, THREE - festive avatar outfits to wear.

Teachers can enter the contest here.

Join our Holiday Contest!


To bring in the holiday season, we’re planning our biggest ever mathematics contest.

It’ll run from December 6-12. As usual, you can play at any time through that week, at school or at home. It’ll only take an hour or so to get a decent score. 

A week before the contest starts, on November 28, millions of Sumdog players across the USA will be celebrating Thanksgiving. So to start the fun, we’ll give all students registered for the contest by November 21 a special Thanksgiving turkey outfit for their on-screen avatar.

Register your students here.

Sumdog Writing is coming soon!

We’ve been working hard on a new set of games to teach writing. 

They let students work together to develop their writing skills, using safe, enjoyable games.

Before the launch, you can try one of our new typing games: Candy.

Type the words Sumdog shows you, and then shoot candy with toothpaste. It’ll adapt its difficulty to your keyboard skills.

We’d love to know what you think of it, so please give it a try!

Welcome to your dressing room!

Have your students been collecting lots of items from Sumdog’s shop?

Now, at the bottom right of the student homepage, they simply need to click the “clothes” panel to quickly browse all the stuff they’ve bought.

Any Hollywood Heroes outfits they have will also appear here.
