Sumdog’s kitchen is coming

Play each week…
get your Sumdog Kitchen!

We’re going to add a new room to Sumdog’s on-screen house: a kitchen. It’s the first time we’ve added a new room.

Every student who uses Sumdog during May will receive this extra room.

We’ll help decorate it, too. For each of the next twelve weeks, there’s a new item of kitchen furniture to collect – simply by playing Sumdog.

Your students will receive all of the items they collect when they play in May.

It’s the best of both worlds: lots of mathematics practice – and a shiny new kitchen!

About Sumdog’s House

Sumdog’s on-screen house is a great motivation for your students.

Every correct answer they give earns them virtual coins – which they can use to decorate their house.

As teachers, you can control when they access the house during school hours: for example, you can open it as a reward at the end of class.

“My family is proud that I came first”

Students have been working hard, having fun and winning prizes in Sumdog’s free regional and national mathematics contests.

Contests are fair for everyone. Scores are based on the class average and questions are adapted to each student’s ability.

Here’s Graettinger-Terril School in Iowa hard at work in a local contest. They even compete at weekends and holidays:
Whitehirst Park School find it exciting to work as a team and see which other schools are competing.
“I like to concentrate so that I get most of my questions correct. My family is proud that I came first.” 
Well done, Kyle!
There’s still time for your students to join in. It’s easy to get involved – all you have to do is click here to enter your class.
We’d love to see your pictures on Twitter or Facebook. Use the hastag #SumdogContests to share!

Sumdog’s newest roster


Easier student management

We’ve made it much easier to manage your students. Here’s what you can do on the new roster: 

  • Easily move students by clicking and dragging their names
  • View and print login details
  • Click a class to see and add new students
  • Add new classes
  • View all the classes on your roster by clicking ‘show all classes’

We’d really love to hear what you think of these recent changes. If you have any feedback, please use our contact form to get in touch.

Set homework on Sumdog


Give your students a challenge

Create a Sumdog challenge for homework to encourage your students to practise skills they’ve been working on in class. For example, challenge them to answer 100 questions on multiplication.

Sumdog has hundreds of skills you can choose from.

Students play the games as normal. When they reach the target they are rewarded with bonus coins to spend in the Sumdog house.

To set it up, click the ‘activities’ button on the left of your teacher dashboard and choose ‘create challenge’.


Track their progress

Save time on marking by viewing which students have accomplished the goal alongside questions attempted, accuracy and correct answers.


Challenges are a subscription feature. If you are not subscribed we’d still love you to try them out. If you’re interested in a free trial please email

Glasgow study: 1½ years’ progress in 6 months

We compared students using Sumdog frequently with those using it less. Those averaging over 1 hour weekly made 1½ years’ curriculum progress.

This Sumdog study investigated how the length of time using Sumdog impacts maths attainment.

The study was overseen by an academic from Glasgow University. To measure the acceleration in learning, the study relied on the natural variations in the length of time Sumdog was used from one class to the next. For pre- and post- testing, the study used Sumdog’s own diagnostic test. To investigate this with more accuracy, we plan to conduct a new study with independent testing.

Pupils and teachers observed an improvement in both mathematics ability and attitude towards learning mathematics.

News about our games


Changes to our free games

Sumdog is more popular than ever, and is growing quickly.

However, with many schools using only the free games, the cost of running Sumdog is rising.

From today, to help manage the load on our servers, the number of free games will drop to 10 (6 in our apps).

If your students aren’t subscribed, and they choose a premium game, they’ll see a message about this.
We’ve made sure that some of the most popular games remain free for everyone to play.

Why have subscriptions?

When schools subscribe, it lets us continue to support and improve Sumdog.

In 2016, we’ve doubled the range of free mathematics skills, giving complete coverage for ages 5 – 11. We’ve also improved many of the existing skills.

So if you subscribe, you’re helping us make Sumdog the best it can be for your students.

If you have any questions, or need our help with anything, please talk to us.
