Identify a missing part when a whole is partitioned into two parts

Maths

In this unit pupils will represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into 2 parts. In the future unit pupils will explain 11-19 cardinally and ordinally. They will double and halve numbers 6-9. They will add and subtract within 20.

In prior learning, pupils will have explored the composition of numbers to 10 and be able to subitise up to 5. In this unit pupils will represent numbers 6 to 10 by partitioning in different ways and learn what odd and even numbers are and how they can be partitioned.

Composition of numbers 6 to 10

Look at the bar model. What is the missing part?

Lucas has 7 counters in total. How many are hidden in his hand?

Jacob is going to hop 8 times. He has already hopped 4 times. How many more hops does he need to do?

A ladybird is climbing up a flower. The flower is 9 cm tall and the ladybird is 2 cm up. How much further does it need to go? {{ }} cm

Jacob and Laura are both counting cars. Jacob counts 3 cars. Laura counts 6 cars. What is the whole? {{ }} cars

Jacob counted 3 cars and Laura counted 6 cars.

Jacob counted 3 cars and Laura counted 7 cars.

Jacob counted 5 cars and Laura counted 5 cars.

Jacob counted 9 cars and Laura counted 0 cars.

Jacob counted 9 cars and Laura counted 1 car.

Jacob and Laura counted 10 cars.
Tick the options that could show what Jacob and Laura counted.

What type of numbers are shown on the number line?

What number has been partitioned and shown in the bar model?

What is the missing part in this number line representation?

Match the numbers so that they combine to make 8 as the whole.

Lucas is going to clap 6 times. He has already clapped 2 times. How many more claps does he need to do?
