This week we will be learning how to create and use part-whole models.
Look at this picture. How many children are there?
How many children are in the red hoop?
How many children are in the blue hoop?
How many children are there altogether?
We can show how many children there are and how they were grouped by using a part-whole model like this one.
Can you see the total number of children in this part-whole model?
Can you see the children in the red hoop in this model?
Can you see the number of children in the blue hoop in this model?
Now the children have moved! Can you use counters to show the groups and complete the part whole model?
The children have moved again! Which of these part whole models match the diagram?
How could these children get into groups? Is there more than one way?
Can you group the children and complete a part-whole model to describe the arrangement?
Can you find at least 3 ways to group the children?
Here are some pencils.
How many are on the table? How many are in the pot? How many are there altogether?
Complete the part-whole model to describe the pencils.
Can you write this as a number sentence?
Use counters or you can draw in two circles on paper to show the groups of pencils in the picture below.
Now complete a part-whole model to show the groups of pencils.
Can you spot the mistakes in these part-whole models?
Can you organise these beads into two groups and complete a part-whole model to describe your groups?
How many different ways can you find to group the beads?
Write a number sentence to match your part-whole models.
Now look at the glasses of squash.
How many glasses of green squash are there?
How many glasses of orange squash are there?
How many glasses of squash are there altogether.
Complete the part-whole model to show how the glasses of squash have been grouped.
Look at these number sentences.
What's the same? What's different?
How do these number sentences match the part-whole model you have just drawn?
Now look at this vase of flowers.
Complete the part-whole model to describe the vase of flowers.
You can write 4 number sentences using a part-whole model.
Can you complete these number sentences for your part-whole model?
