### 22.1.21 Friday Investigation

This investigation is a low threshold high ceiling investigation, which means that it is accessible for all and is designed to be a bit of fun for a Friday. It is a good opportunity for the children to practise counting and to record findings in different ways. And there's the added bonus that everyone could have a completely different answer and still be right.

As learners we need to find strategies to keep track of where we have got to in terms of numbers of legs, and to regulate and readjust as we get close to twelve. You may even consider creatures with one 'leg' such as slugs and snails, no legs such as snakes, and all the other possibilities for fun. You can record your workings in any way you wish, by drawing the creatures, writing out as number sentences, making the creatures out of play dough or salt dough. It is entirely up to you!

### Key questions

What creatures could there be?

How many legs do they each have?

What's the greatest number of creatures he could have seen?

What's the smallest number of creatures he could have seen?

### Possible extension

You could ask questions such as: What if ... there were twelve creatures? How many legs could that be?

What if there were more legs... 18, 24, 19 ... or fewer?

Today the children need to use their knowledge of commutativity to find the most quick and efficient way to add the three one-digit numbers together.

This means that we can change the order of the numbers we are adding together to help us. Today we are going to need to know and use our number bonds to 10.
