Unit Summary
In this unit pupils will use knowledge of place value to represent a 3-digit number in different ways. They will compare and order 3-digit numbers and position on number lines and unmarked number lines.
Lesson Summary
You will learn to write a 3-digit multiple of 10 as a multiplication equation.
Key Notes
- Base ten blocks and 100s frames can represent multiples of ten.
- The symbol × means multiply or lots of.
- Any 3-digit multiples of ten can be written as a multiplication equation.
Vocabulary To Learn
- Equation: An equation is used to show that one number or calculation is equal to another.
- Multiple: A multiple is the result of multiplying a number by another whole number.
Common Mistakes To Avoid
- Pupils may explain the relationship with multiples of 10 as 'adding a zero' (e.g. 37 x 10 = 370).
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Base ten blocks and 100s frames can represent multiples of ten. The symbol × means multiply or lots of.
2. Use this key word in a maths sentence and explain it clearly. 'Equation'
An equation is used to show that one number or calculation is equal to another. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may explain the relationship with multiples of 10 as 'adding a zero' (e.g. 37 x 10 = 370). Correction: Pupils should be discouraged from doing this. Instead, explore place value, reminding pupils that each 100 represents 10 lots of ten.
