Welcome to Year 1 Maths!

In Year 1, you learn the foundations of maths. Here are the main ideas you’ll explore, with simple explanations and examples.

1) Counting, Reading, and Writing Numbers

  • Count forwards from 0 to 100 and backwards from 20 to 0.
  • Write numbers correctly, including digits and number words (one, two, three, ...).
  • Watch for patterns in numbers (e.g., 2, 4, 6 are all even).

2) Place Value: Tens and Ones

  • Understand that a two-digit number is made of tens and ones (e.g., 47 = 4 tens and 7 ones).
  • Recognize the value of each digit based on its position.
  • Use manipulatives (blocks or beads) to build numbers like 23 or 58.

3) Addition

  • Combine two groups to find the total (e.g., 5 + 3 = 8).
  • Use counting on fingers, fingers tricks, or number lines to add.
  • Use a number line: start at the first number and jump forward by the second number.
  • Learn the concept of ‘adding on’ to find sums up to 20.

4) Subtraction

  • Take away objects to find how many are left (e.g., 7 − 4 = 3).
  • Use counting back, number lines, or objects to subtract.
  • Introduce the idea of subtraction as finding the difference between two quantities.

5) Practical Understanding and Problem Solving

  • Story problems: matching numbers to real-life situations (e.g., sharing snacks).
  • Explain your thinking: show how you solve a problem, not just the answer.
  • Use everyday objects (buttons, coins, toys) to practise counting, adding, and taking away.

6) Shape, Space, and Measures (Basic Introductions)

  • Recognize common shapes: circle, square, triangle, rectangle.
  • Discuss size, length, weight, and how things fit together.

Tips for Practice at Home

  • Count everyday items: apples, stairs, socks.
  • Play simple addition and subtraction games using dice or cards.
  • Use a number line for adding and subtracting up to 20.
  • Encourage talking about maths: describe what you see and how you know your answer.

Key idea: Year 1 builds confidence with numbers, understanding place value, and solving first addition and subtraction problems using fingers, objects, and simple number lines.
