This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will describe how objects are grouped and will represent equal groups as repeated addition and multiplication.
Lesson Summary
You will learn to identify and explain each part of a multiplication equation.
Key Notes
- The number of groups is called a factor in a multiplication equation.
- The group size is also called a factor in a multiplication.
- The number of objects overall is called the product of the multiplication.
Vocabulary To Learn
- Product: A product is the result of two or more numbers multiplied together.
- Multiplication equation: An equation is used to show that one number or calculation is equal to another. Multiplication equations use × and = symbols.
- Factor: A factor is a number which exactly divides another whole number.
Common Mistakes To Avoid
- Children may confuse the terminology of factor and product and therefore be inaccurate when describing equations.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
The number of groups is called a factor in a multiplication equation. The group size is also called a factor in a multiplication.
2. Use this key word in a maths sentence and explain it clearly. 'Product'
A product is the result of two or more numbers multiplied together. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children may confuse the terminology of factor and product and therefore be inaccurate when describing equations. Correction: Take time to clearly model use of terminology and ask questions such as: 'What does the 3 represent?' 'What does the 5 represent?' 'What does the 15 represent?' Continue to explicitly use key terms such as factor and products within explanation.
