Partition the numbers 8 and 9 in different ways

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

What is the missing whole in this bar model?

Izzy thinks the missing part shown on this number line is 2
Is she right?

Andeep is going to clap 9 times. He has already clapped 5 times. How many more claps does he need to do?

Which set of counters will come next if we are ordering the ways to partition 9 systematically?

Look at the table showing partitions of 8 counters. What number is missing in the table?

Look at the counters and the part-part-whole model. What is the missing part?

What is the whole missing from this bar model?

Andeep thinks the whole shown on this number line is 7 
Is he right?
