A pictorial representation that shows the whole and its parts.

Solve problems using a part-whole model to represent a whole partitioned into more than two parts

Maths

In this unit pupils will explain that items can be compared using length and height, weight/mass and volume/capacity. They will compare sets of objects using equality/inequality symbols. In the future unit pupils will combine 2 or more parts to make a whole. They will learn that addends can be represented in any order and that the = sign is used to show the whole and sum of the parts are equal.

In prior learning, pupils will have had opportunities to use manipulatives to organise counting including using everyday manipulatives, tens frames and through measures. In this unit pupils will explain that items can be compared using length, mass and capacity and use the inequality symbols.

Comparing quantities - part whole relationships

Sofia has 5 counters, Lucas has 3 counters and Jacob has 2 counters. Which part-whole model is showing their counters?

Sofia has 2 counters, Lucas has 2 counters and Jacob has 1 counter. Which part-whole model is showing their counters?

The whole is 6. Sofia has 2 counters and Lucas has 2 counters. How many counters does Jacob have?

The whole is 8. Sofia has 5 counters and Lucas has 2 counters. How many counters does Jacob have?

Which part-whole model is showing Sofia’s counters correctly partitioned?

Which part-whole model is showing Jacob’s counters correctly partitioned?
