Fingers up and fingers down 

Using two hands, show a random number of fingers. How many are up? How many are down?

Sadly, I cannot use this method for number bonds to ten as I don’t have 10 fingers - only 8!

Lego tens

Create blocks of ten in as many ways as possible using two colours.

Ten Frame Mania from Tang Math: click learn and all will become very clear.

Time to put those number bonds to 10 to use to Save the Whale. Don't forget to turn the handle to release the water!

Make 10 has a lot of arrows.

What do they do? They simply move a digit to another and find the sum of those digits.

In the middle image above, if I press the arrow beneath the 9, the 1 moves down and I Make 10.

There are quite a few rules for playing Number Match but if you read and understand them, it will be worth it!

Equalz from plays.org is one of those activities that looks basic and not much fun but when you play it, you will enjoy it as much as I do! Although you will often be looking for a pair of numbers, sometimes three numbers might be needed to make the total (which is at the top of the screen).

I could not get the instructions to work for Tendo from calculators.org but felt that it could be a great game. When I discovered that any combo that makes ten in a row or column then disappears and gave me points, I knew that I loved this game!

To make 10, the dice do not need to be next to each other; they simply need to be in the same row or column. 

Connect from toytheater.com is a lot of fun, but sometimes it can be frustrating: that’s all part of the fun! In this game, you can slide the blocks from left to right and even allow them to drop to a lower row if there is enough room to fall. Play a few times and you will get the hang of it.

Ten frames are great for visualising number bonds to ten and I particularly like the colourful aliens! Alternative frames can be selected and this would be effective for understanding number bonds to 20.

Playing cards - Deal one card at a time. Ask the child to give the corresponding bond to ten/twenty. You might want to remove the Jacks, Queens and Kings to ensure greater variety of number bonds.

Who can shout out the number bonds to 10/20 first?


Using triangles with missing information is a great way to represent the relationships between number bonds - simply put the target number (the sum) at the top of the triangle. Perhaps you could have your own whiteboard and have two pieces of information, challenging the learner to work out the missing value. My YouTube video will help you to understand how this can be done.

Want to practise this skill? Try this activity from Tang Math. The diagrams are great as they are similar to my Terrific Triangles.

Alternatively, you might want to catch some aliens in Aliens Addends.

Numbots challenges - Challenges on Numbots are now accessible without completing every level proceeding them. This means that the number bond challenges are a great way to practise number bonds to 10, 20 and 100 (all).

Count on Catapult  

This is a great game for applying number bonds to reach the next multiple of ten (and to knock down a castle).
