Use animals as 'non-standard' units to weigh others.   'We're going to weigh the duck! What shall we use to weigh with?' 'How many hedgehogs do you think we will need to balance the scales? Count with me.' 'I've put on 2, how many more do you think are needed? Come and count on some more to see if we are right.' 'Whoops, I've put too many on. How many shall I take off?'

A versatile counting situation. Add, subtract and compare sets. 'I'm going to put some of these creatures in the sea. Can you count them as I put them in?' 'There are 2 lobsters already. How many will there be if I put 2 more in?' 'What happens if I go really quickly, can you keep up? Now there are lots of them, can you help organise them to make it easier to count?'

A versatile teaching tool! You can teach lots of different number concepts using it. "I've hidden some numbers. Can you work out what they are by looking at the ones that are left? Do you think the numbers are going up in steps of 1, 2 or 5?" "I've made a number pattern. It goes like this ...0,3,6,9. How high can you get carrying this pattern on? Let's check your answers on the number square!"

A versatile teaching tool! You can teach lots of different number concepts using it. 'I'm making some number cards. Say the number as I make each one. Who wants to click this triangle and count the spots to make sure we are right?' 'Look at the numbers I've made ...8, 3, 12, 20. Which of those numbers is largest? Which number is smallest? Who wants to put the numbers in order? Are you going to start with the smallest or the largest?'
