Operations in IB PYP Grade 1 Mathematics

Operations are the things we do with numbers: putting groups together (addition), taking some away (subtraction) and seeing how numbers split into parts (number bonds). In the PYP Number strand, Grade 1 learners build these ideas with pictures, counters, ten frames and number lines before they move to written number sentences.

PYP learning is inquiry-based, so every worksheet here is short, colourful and playful, with a friendly animal guide and a teacher answer key on page 2.

What learners practise

  • Adding two groups and finding the total
  • Taking away to find how many are left
  • Number bonds that make 5, 10 and 20
  • Using number lines and ten frames to add and subtract
  • Reading short stories and writing the number sentence

Operations at a glance

  • Addition: 4 + 3 = 7 means “put together”
  • Subtraction: 9 − 4 = 5 means “take away”
  • Number bonds: 6 and 4 are partners that make 10
  • Fact families: 3 + 4 = 7, 4 + 3 = 7, 7 − 3 = 4 and 7 − 4 = 3

For students

Read each instruction carefully, try every question and colour the animal when you finish.

For parents

Print on A4, read the instructions aloud together and let your child work alone before you check.

For teachers

Use a worksheet as a starter, homework or exit ticket. Each one has a name, class and date box and an answer key.

Teaching tip

Let children act out each story with real objects first. Only when they can show the answer with counters should they move to the number sentence.

Quick answers

Who is the Operations page for?

It is for IB PYP Grade 1 Mathematics learners, typically aged 6–7, and for the parents and teachers who support them.

What is the difference between addition and subtraction?

Addition puts groups together to make a bigger group. Subtraction takes some away, or finds the difference between two groups.

Which numbers do the worksheets use?

Most start within 10 and then move on to numbers within 20, so children build confidence step by step.

How should I use these worksheets?

Pick one worksheet, let your child try it without help first, then check together with the answer key on page 2. Short sessions of five to ten minutes, a few times a week, work best.
