Here’s a game we’ve adapted slightly for the park. We used large Prime Colours cards which we printed out and laminated for this. I guess you could use a normal pack too. Or make your own pack.

We laid the cards out in a grid with just one of each card included. Players stood around the grid, ready to jump in.

To start playing someone chooses a target card and takes it out of the grid showing everyone the number. Then all the players had to choose a different card (by jumping on it of course) and the player who gets closest to the target number wins the card.

We kept going until everyone had won at least 1 card but of course you can make it more competitive. This can of course be played inside on a table too using playing pieces instead of jumping on the cards but…

The goal of the game is to help children remember the cards and in turn their multiplication facts. Some children will remember a few cards others will need to work them out. Whichever tactic they use, it’s all good practice.

This was a great activity, but it reminded me of a conversation I had with an outdoor learning specialist that, basically, this is an indoor concept that has been brought outside. It got me thinking of a version of prime colours that used outdoor concepts such as perhaps earth, stones and flowers. Still working on that idea…

]]>There is a way to practise maths that looks like doing it backwards, but actually is a far more effective and creative way to practice recall of arithmetic facts.

Start with a number such as 12 and write it in the centre of the sheet. Your goal is to see how many calculations you can find that equal it. You can also find information about special numbers nearby that number.

This is a much more creative and open approach to practise. You do not need to spend a long time on it but try to do it regularly. Even better, do this with friends/family and see who comes up with the most unusual calculation.

Prime Colours lends itself to this style of practice. Each card gets you to think about the calculations that result in the number. The card on the right is the number 20.

Depending on the Prime Colours’ activities that you’ve done, you could find any of the following calculations.

4 x 5 | 2 x 10 | 10 + 10 | 12 + 8 | 2 + 3 + 4 + 5 + 6

Getting to know numbers in this way is what real fluency is about. You can work collaboratively on a sheet and of course upgrade a sheet that is too easy by finding something else to find.

If you can take a few cards with you, in your pocket say, you can do this practice any time you have a spare minute and before long, you will have build up valuable connections between numbers.

]]>Concepts and misconceptions are at the heart of maths education. Our goal is to give out children an understanding of concepts that they trust and can use. We may have to do this through knowledge and skills because (except in The Matrix) we cannot download whole concepts into people’s heads. We can run into difficulties if we assume that certain concepts are in place based only on the assessment of a few key facts and skills.

Let’s start with a simple one. Lots of us either learn or realise that if we multiply whole numbers by 10, we can just add a zero to the end of the number to get the answer. Most educators realise that this is a very limited trick but it allows children to develop ways to respond to questions before they can deal with the concept of place value.

The problem is that the technique suggests that you can just append numbers here and there. It is a way to get a correct answer but not a mathematical operation that works in any other situation

This type of problem is commonly seen in algebra when people talk about moving numbers or variables to the other side. It’s not so bad to do this once you have a strong concept of algebra but before that, it tends to develop real misconceptions about how maths works.

If all you learn about multiplication is times tables and perhaps the column method, it won’t be too

It is really important for developing

Here are a few things that will really help you broaden the concept of multiplication for your children or students.

1) Try the Multiplication Explorers course by Natural Math

2) Use grids, tables and webs to model multiplication as well as lists

3)
