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 how each part of a multiplication and division equation relates to a story.
Key Notes
- A division equation has three parts - the dividend, the divisor and the quotient.
- For grouping, the divisor represents the size of each group. For sharing, the divisor represents the number of groups.
- Multiplication equations can be used to solve division problems.
Vocabulary To Learn
- Dividend: The dividend is the number being divided.
- Divisor: The divisor is a number that will divide exactly.
- Quotient: The quotient is the results of the dividend being divided by the divisor.
Common Mistakes To Avoid
- The difference between grouping and sharing is a distinction that some may find tricky to grasp.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A division equation has three parts - the dividend, the divisor and the quotient. For grouping, the divisor represents the size of each group. For sharing, the divisor represents the number of groups.
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: The difference between grouping and sharing is a distinction that some may find tricky to grasp. Correction: Remind children about the importance of understanding the different structures of division when interpreting a story. You could stress the difference, dividing the class into teams using grouping, then sharing.
