Summary

When playing in Garage and Arena games our data-informed algorithm issues each pupil with questions that are just right for them, every time. This will optimise every practice session and accelerate their progress to becoming a Rock Star!

How it starts

To begin with, we have no data on a pupil. We'd say that their heatmap is blank.

So for their first Garage or Arena game, we'll assume they're starting at the beginning and kick off with six easy questions from the 10 times table.

To cement those six facts, they'll also get the six matching division questions. For example, if they're issued with 2×10, they'll also get 20÷10. (Further reading: our take on the importance of division when learning multiplication.)

Tip: if your pupils are not beginners, get them to play a Gig game. Gigs jump start their heatmap and provide enough data after 5 minutes to move pupils to the best point from which to continue. Learn more about Gigs.


How it continues

As they carry on answering questions, the evidence we have of their recall gets richer and richer. Our algorithm uses that evidence before EVERY Garage and Arena game to update which questions to issue each pupil.

The order of tables that the algorithm follows can be seen at the top of the heatmap.

As their knowledge and recall continues to improve, new facts will be released into the question pool. So you'll see their heatmap not only turn from red to green but also start to fill out from the top left to the bottom right.


How it ends

The result of this steady and adaptive approach is swifter progress towards excellent recall of all the facts in the selected tables.

What if parents ask: "my child has been set specific tables but they're only getting a few questions; what's happening?"

Suppose the child has been set the 2s, 5s and 10s You might think that they'll immediately get all the questions from those tables. However, that amounts to more than 90 different facts when you include all the various multiplication and division forms, which will slow progress and reduce confidence.

So instead of giving them a random assortment of 90+ questions, the TTRS smart algorithm works out the 6 highest priority facts from WITHIN the selected tables.

Example

This user has been set the 2s, 5s and 10s but they'll only get the six highlighted questions (and associated division questions) as they have been given highest priority by our system. The image demonstrates how questions have been picked from within the selected tables.

What happens as the child gets faster at one of those six questions?

It's no longer a question they need to work on so the algorithm scans the rest of the selected tables in search of the most up to date batch of priority questions.

Will they ever practise all the selected tables, not just 6 questions at a time?

The short answer is yes; in time they'll end up with all facts from the selected tables but only once there's evidence that they're ready.

Don't fear...the tables chosen for them (whether it's one table, a few tables or all the tables) will be covered in full, just in a very targeted, progressive and individualised way.

After something different?

Perhaps you'd prefer your pupils to get a random weighting of all the tables; in that case they're best to play in Studio, Festival or Rock Slam.
