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.



Our iPad apps are now free

Good news: we’ve decided to make all our iPad apps completely free - whether or not you have a subscription.

Our first app lets you play our popular Snowball game, both at home and at school.

We are hoping to publish a new iPad game every month, starting November.

Get the Snowball app now - it’s available in the iTunes store!

Setting a one-minute challenge

This week, we’ve added some new options to Sumdog’s activities.

They let you use Sumdog to set a one minute test, to check your students’ fluency on a chosen skill.

Here’s a video to show you how:
