KS1 and KS2 Part Whole Models Worksheets

Part whole models are used to visually represent the relationship between a ‘whole’ and its parts. It is particularly useful in helping children understand the concept of partitioning—a process of splitting a number into smaller parts. These models often come in the form of ‘cherry diagrams’, as can be seen throughout our resources. 

The part-whole model helps students understand addition and subtraction by partitioning numbers into manageable parts. This concept is also helpful in developing a deeper understanding of number bonds (the pairs of numbers that add up to a given total).  The part-whole model is typically introduced during early years and KS1, however they also remain useful in KS2. 

In the Cazoom collection you can find part whole being used to: introduce addition and subtraction statements, add and subtract numbers, doubling, partitioning numbers, and making 1 with fractions and decimals.  New worksheets are added regularly, ensuring there’s always something fresh to boost your students’ understanding and keep them engaged.

What are part whole models in maths?

Part-whole models visually represent how a whole can be split into smaller parts. Often illustrated using ‘cherry diagrams,’ these models help learners see how numbers combine and separate. For example, the number 10 can be partitioned into 7 and 3, or 6 and 4, giving students a strong foundation in addition, subtraction, and number bonds. These models also extend to fractions and decimals, making them a versatile tool for exploring numerical relationships.

importance of part whole models

Part-whole models are essential in maths education because they:

  • Help learners visualise the relationship between a whole and its parts.
  • Support understanding of addition and subtraction through partitioning.
  • Reinforce the concept of number bonds, aiding mental maths skills.
  • Provide a foundation for more advanced concepts, such as fractions and decimals.
  • Encourage logical thinking and problem-solving by breaking numbers into manageable parts.

uses of part whole models

Part-whole models have a wide range of applications in the classroom and beyond:

  • Addition and Subtraction: Break numbers into parts to simplify calculations.
  • Doubling and Partitioning: Explore number relationships for mental maths and problem-solving.
  • Fractions and Decimals: Show how fractions and decimals can combine to form a whole.
  • Making 1: Use part-whole models to visualise ways to create 1 with different combinations.
