Introduction to Number Puzzles

Hello, Year 6! Today, we’re going to explore a fun and exciting way to play with numbers: number puzzles! A number puzzle is a challenge where you have to figure out the missing numbers or solve a mystery with numbers.

What is a Number Puzzle?

A number puzzle can be anything from finding patterns with numbers, solving equations, or even cracking a code! The aim is to use your maths skills to find the answer.

Key Rules to Remember

  1. Look for Patterns: Many number puzzles rely on patterns. Check if the numbers are increasing or decreasing.
  2. Use Operations: You might need to add, subtract, multiply, or divide to find the answer.
  3. Work Step-by-Step: Don’t rush! Take your time and solve the puzzle step-by-step.
  4. Check Your Work: Always go back and see if your answer makes sense.

Tips and Tricks

  • Write It Down: Sometimes, writing the numbers down can help you see the pattern better.
  • Try Different Approaches: If one method doesn’t work, try another! There’s often more than one way to solve a puzzle.
  • Talk It Out: Discussing the puzzle with a friend can help you find the answer faster.

Example of a Simple Number Puzzle

Let’s say we have the puzzle:

What number is missing?

2, 4, __, 8, 10

Here, we can see that the numbers are increasing by 2 each time. So the missing number must be 6.
