Year 4 - Maths

Explain where zero can be part of a multiplication or division expression and the impact it has

Understand and represent multiplicative structures

Unit Summary

In this unit pupils will explain how each part of a multiplication and division equation relates to a story. They will partition one of the factors in a multiplication equation in different ways using representations.

Lesson Summary

You will learn to explain where zero can be part of a multiplication or division expression and the impact it has.

Key Notes

  • When zero is a factor, the product is zero.
  • Zero can represent the group size or the number of groups in a multiplication context.
  • In a division, zero can be the dividend but not the divisor.

Vocabulary To Learn

  • Dividend: The dividend is the number being divided.
  • Divisor: The divisor is a number that will divide the dividend exactly.
  • Quotient: The quotient is the result of the dividend being divided by the divisor.

Common Mistakes To Avoid

  • Many pupils will come into the lesson believing that the value of 3 ÷ 0 is 0

3 Quick Questions (With Answers)

1. Solve this in steps: explain the method from this lesson and why each step matters.

When zero is a factor, the product is zero. Zero can represent the group size or the number of groups in a multiplication context.

2. Use this key word in a maths sentence and explain it clearly. 'Dividend'

The dividend is the number being divided. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Many pupils will come into the lesson believing that the value of 3 ÷ 0 is 0. Correction: Make sure that you use other examples of related multiplication and division equations to show how they can help to disprove the idea that the divisor can be used as zero. Keep them clearly displayed on the learning wall.
