16 Fun Back to School Maths Activities for KS2

Back to school, and back to maths with our roundup of 16 fun back to school maths activities to start your term the way you want it go on, even in the face of any brain drain… 

Sometimes referred to as “the summer slide”,  brain drain, whether over summer or other holidays, is the loss of knowledge and skills which were acquired during the previous school term or year.

Primary Maths seems to be the subject which is hit the hardest, with industry experts suggesting “2.6 months of Maths skills are lost over the summer.Yikes!

If we’ve caught you at the wrong end of term, check out our other blog packed with our favourite fun end of term maths activities.

Back to school and back to maths lessons

Your new pupils’ retention of last year’s Maths may not be as strong you hoped. But wait! There’s hope. Here at Third Space Learning, we’re experts at engaging primary pupils in Maths, even the most forgetful.

recap fractions and decimals slide
Every Third Space lesson starts with a recap of prior knowledge required: here’s an example from a lesson on multiplying decimals.

So, to get you and them back into the swing for their Maths lessons, we’ve trawled the internet to compile a list of the top 16 (coincidentally happens to be a square number!) engaging, fun and effective back to school Maths activities to shake up your pupils and clear out those cognitive cobwebs.

Lots of emphasis on problem solving and reasoning as usual!

All these fun maths activities are free

We had Year 6 in mind when we created this list of back to school maths activities, but we reckon most of them can be adapted and used in other KS2 years – Year 3, Year 4, or Year 5.

In fact they’re suitable for any day of the week and any stage of term, but right now, at the start of term, we recommend you use them to help pupils to beat the summer slide in maths, develop depth and justify their reasoning. These activities are teacher approved and fun, at a time when fun is what you need to settle your class.

As an added bonus we’ve also got 4 free Back to School Maths Quizzes (for Years 3, 4, 5, 6,) for you to download and help diagnose your pupils principle gaps in Maths.

1. How Many Squares and How Many Triangles?

Pupils use a quick online activity to find as many squares and triangles in the diagram as possible, requiring them to think outside the square. Or triangle!

Time:10 – 20 mins
Why we chose it:Great for a starter on the first day back.  Pupils love counting the objects when you press the play button!
Our suggestion:Make it into a competition – closest person wins a prize! Get pupils to commit to an answer – back of books.
How to support:Ask them to work in pairs. Or you could ask of an example of another square other than the individual ones.
How to extend:When asking for results, ask pupils to think of an efficient way to record the data.

2. Here’s The Answer, What’s The Question?

Give pupils a complete calculation and ask them to write their own word problem.

Time:10 – 15 mins
Why we chose it:It’s open ended! Just think of the responses, some pupils may even surprise you!
Our Suggestions:Ask pupils to copy the calculations in their books. Perhaps you could ask them why you have set your workings out in that way?
How to support:Ask pupils to come up with an example in pairs first so that they are having to verbalise their reasoning with one another. Then ask them to come up with another example all by themselves.
How to extend:Make it a 2 or multiple step calculation.

3. Education Estimation

Estimate the number of pens/pencils/books (and glue sticks?!) etc needed for the class/year group/whole school in this fun and informative activity.

primary maths pens
Time:20 – 25 minutes
Why we chose it:Estimation is a key skill to practise and a nice way to link Maths to real life context. Plus, maybe they will be more respectful with your stationery?
Our Suggestion:If you are brave enough, get out a whole box of pencils at the start so that (as a whole class) pupils can manipulate/visualise how many would be need. Again, only if you’re brave.
How to support:Use simpler numbers such as smaller containers, larger items or provide a comparison first. e.g. Here’s one cup and it has ten pencils in. Now how many do you think are in this cup?
How to extend:Add in a cost per item. “What if I had 10, 20, 15 of these pots/packs?” “What if I had twice as many?” “What if I gave a third of them away?”


Get pupils to chose from a list of numbers on the board (or they can make them up). Then display a sequence of prepared numbers on the board and pupils cross them off on their grid. When pupils cross off all of their numbers they shout “BINGO!”

Back to school maths bingo
Time:15-20 mins
Why we chose it:You can do so much with them! Easiest way is to get the pupils to draw their own bingo grids on their mini whiteboards and fill in numbers e.g. “Choose 9 of the numbers from the list on the board.” or “Write down 9 multiples of 10 between 100 and 500.”
Our suggestion:Do not reinvent the wheel – there are loads of bingo cards out there for you to use for free! Also, write down the answers to the questions (in order of course) before and this makes it easier to check.
How to support:Create cards with easier numbers. If in a mixed ability class, try to use a variety of questions, some easier than others.
How to extend:Create cards whereby the numbers are calculations/times tables (eg instead of 64 you could put 8 x 8).
Link to activity:TES has a plethora of them (you willl need to sign in/create an account.)

5. Grid Multiplication

Pupils have to use their times table knowledge to find the missing numbers.

grid for multiplication - back to school
Time:10 – 15 mins
Why we chose it:Great for practising times tables and looking at the inverse and how they link with one another.
Our Suggestion:Do one as an example with the whole class. Then get pupils to create one for their friends to answer. They can do this by creating one on their whiteboards then just rubbing out some of the answers. Nice way to get pupils practising multiplication. They obviously will make it as hard as they can for them. What are friends for eh?
How to support:Pair work or possibly a times table grid.
How to extend:Create a grid that requires a two step solution like the example above.

Time:10-20 mins
Why we chose it:It requires pupils to use the four operations and they really see it as a great challenge! Let’s play countdown!
Our Suggestion:Two from the top and four from the bottom is the easiest.
How to support:Give them an extension of time (say another 10 seconds?). Or ask a pupil what they would do first so that those struggling can have a start in the right direction. You could also provide struggling pupils with list of a key number facts e.g. 2 x 75 = 150.
How to extend:Four from the top and two from the bottom of course!

Time:5 – 15 mins (depending on how many you do!)
Why we chose it:This starter is great for gauging how much a pupil has retained about a topic. And do you know the best thing about this? There is no wrong answer as long as a pupil can justify their answer!
Our Suggestion:Do this activity as a class as the conversation could just take off!
How to support:Have a combination where there is no wrong answer (like the one above).
How to extend:Design a combination where 3 (or 4) are the same and only one is the odd one out. Great for simplest form!

11. Guess My…

Teacher to think of a number/shape/angle etc. Then, pupils are to ask questions to the teacher where the answer can only be yes or no. Challenge pupils to guess within a set number of questions.

Guessing maths game
Time:5 – 15 mins
Why we chose it:It requires pupils to be thinking about the questions they are asking. They are also required to use key terminology and remember previous answers too!

Our Suggestion:Do an example first. Perhaps include one with a misconception that does not follow the order of operations.
How to support:You could decrease it to three ways to make 24.
How to extend:Include variations such as square numbers, square roots, only odd/even numbers must be used or even must use all different numbers in each equations.

13. Fizz Buzz Game

Decide on the multiplication table you’re going to chant. In turns, pupils list the multiples in order, but are not allowed to say numbers that match with a rule (eg numbers that are divisible by 2). Instead, they have to replace that number with a word that you have come up with.

Fizz, bang maths game
Time:5 – 10 mins
Why we chose it:It gets them on their feet, improves their times tables and we bet you will end up in fits of giggles!
Our Suggestion:Go crazy with the word! We came up with pickle, brolly and trifle!
How to support:Make the rule easier.
How to extend:Have two rules to keep them on their toes!
