Starter: practice subitising using the Dice Subitising PowerPoint. This is a little trickier so they might need the count the high numbers.
Look at the picture below and answer the questions:
Can you count the items in each picture? Which is different?
How do you know?
• What does ‘odd one out’ mean?
• Which picture do you think is the odd one out? Why?
• Is the ladybird the odd one out? Why?
• Could the flowers be the odd one out? Why? [Because they
are plants and the others are animals.]
• Could any other picture be the odd one out? Why not?
Give children a piece of paper split into four sections to create their own odd one out game. Children need to collect items to put in each section. They could use toy animals or groups of items in each section to represent numbers up to 8, such as 5 pencils, 5 pairs of scissors, 5 rubbers and 6 crayons. Children should swap games and identify which is the odd one out.
To make this game easier you could use your cubes or smaller number. Only go up to 6. Spread the cubes out into small groups of 2,2,1 for example. Which group is different? Why?
