Wednesday 21st October
Pass a teddy back and forth and count to 10, with pass say one number name. When you get to 10 start again at 1. Try passing it around but starting at 10 and counting backwards to 1.
Tell your child a story – once upon a time there were 2 pigs in the field. The farmer came along and brought one sheep to put in the field.
Ask: How many animals are in the field? Use plastic animals and a green material for the field to show the story as it is happening. Ask the children how many animals there are. Ask – how do you know there are 3? Take children’s responses – some might say that they know because they counted so let them show this. Establish that we know it is 3 because 2 and 1 more makes 3. Show them how they can show this on their fingers.
Tell the children that you are going to draw a picture to show this story but that you aren’t very good at drawing animals so you will draw a circle for a pig and a fluffy shape for the sheep. Write a 3 to show that there are 3 animals altogether.
Tell the second story – last night I baked 3 cakes – put 3 cakes on a plate (change the story to match the items you have at home). I was so hungry when I could smell the delicious cakes that I ate one.
How many cakes are left? Ask the children how many are left and show them that you need to take away one of the cakes to show you have eaten it.
Tell them that you are going to draw a picture to show the story. Tell them that you are drawing 3 cakes because that’s how many you baked. Then looked puzzled – tell them that you don’t know how to show that you ate one of the cakes. Explain that you can’t take it away because it is drawn on the paper. Ask for ideas and agree that you could cross it out to show that you have eaten it. Write a ‘2’ to show that there are 2 cakes left.
Then – there was one duck swimming in the pond. Quack quack said the duck and his two friends came to join in him in the pond. How many ducks are there now? Model this with ducks and a pond. When you have agreed that it is 3 ask – how can I draw this? What do I need to draw? Ducks. Where was the first duck? In the pond. Draw a circle – so this can be my pond. How many ducks do I need to draw in it? 1. How many ducks came along when he quacked? 2 Where should I draw these ducks? To the side of the pond. What number do I need to write to show how many ducks there are altogether? 3
Then – 3 cars were parked in the car park at Morrisons. Two people had finished their shopping so drove their cars home. How many cars are left now? Model this with cars. When you have agreed that it is 1 ask – how can I draw this? What do I need to draw? How many do I need to draw? What do I need to do to show the two that drove away? What number do I need to write to show how many are left?
The aim is to use the vocabulary involved in adding and subtracting (two add one is three. Three take away one is two, three take away two is one) in practical activities and discussion.
I want the children to be able to calculate using up to 3 items and be able to subitise and count to 3.
Leave the resources out and encourage the children to tell their own stories. Can they use the language of addition and subtraction? Can they explain how they know the answer? Can they add and subtract with up to 3 objects? Look out for children using this language in their play.
