Welcome to Year 3 Math!

Here are the common math topics you’ll learn in Year 3 (around age 7). Each section has simple explanations and quick examples to help you practice.

1. Place Value

Understanding tens and ones helps you read numbers up to 100.

  • Tens are the groups of 10. Example: in 34, there are 3 tens (30).
  • Ones are the single ones. Example: in 34, there are 4 ones (4).
  • So, 34 = 3 tens and 4 ones.

2. Addition

You’ll add numbers using mental math and written methods.

  • Adding 2-digit numbers helps you find totals like 24 + 15.
    • Count up from 24 to 40 (16 more), then add the rest: 40 + 15 = 55.
  • Practice with placing numbers in a column (ones under ones, tens under tens).

3. Subtraction

You’ll learn to subtract using counting back and column method.

  • Example: 29 − 14 → 29 − 14 = 15.
  • Subtract tens and ones carefully, lining them up in columns.

4. Number Bonds to 20

Know pairs of numbers that add to 20.

  • Examples: 0 + 20, 1 + 19, 2 + 18, ..., 10 + 10.
  • These help you add faster and see complements.

5. Multiplication Basics

You’ll start learning the idea of multiplication as groups of equal size.

  • Introduction to times tables, like 2 × 3 = 6 (two groups of three).
  • Use repeatedAddition: 3 + 3 + 3 = 9 means 3 × 3 = 9.

6. Fractions Basics

We begin with simple fractions and sharing equally.

  • If you cut a pizza into 2 equal parts, each part is 1/2.
  • Understand halves and quarters with real objects (cake, fruit).

7. Measure and Money

You’ll compare lengths, weights, and learn about coins and notes.

  • Compare lengths (cm and m).
  • Compare weights (g and kg).
  • Identify coins and their values (pence, pounds).

8. Time and Data

You’ll read clocks and collect simple data.

  • Read o’clock and half past times.
  • Record daily activities and create simple tally charts.

9. Shape and Space

You’ll learn about basic 2D and 3D shapes and simple properties.

  • Identify circles, squares, triangles, rectangles, spheres, cubes.
  • Describe shapes by the number of sides and corners.

Helpful Practice Tips

  • Play quick daily math games (add/subtract flashcards, number bonds).
  • Use real objects for counting, sharing, and measuring (cars, coins, blocks).
  • Ask questions like: How many more do we need to reach 20?
  • Practice mental math by counting in steps (2s, 5s, 10s).
