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 represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into two parts where one of the parts is known.
Lesson Summary
You will learn to partition the numbers 8 and 9 in different ways and organise them in a systematic way.
Key Notes
- Partitioning can be represented on a part-part-whole diagram.
- A bar model can be used to represent ways to partition numbers into two parts.
- The larger the number the greater the number of combinations.
- Being systematic helps you to find all the ways of partitioning a number.
Vocabulary To Learn
- Systematic: Having an order to the way we work, identifying and using patterns.
- Partition: To split a whole up into parts.
- Part-part-whole model: A pictorial representation of a whole and its parts.
Common Mistakes To Avoid
- When using patterns to identify combinations, pupils may struggle to be systematic and not identify all options systematically.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Partitioning can be represented on a part-part-whole diagram. A bar model can be used to represent ways to partition numbers into two parts.
2. Use this key word in a maths sentence and explain it clearly. 'Systematic'
Having an order to the way we work, identifying and using patterns. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: When using patterns to identify combinations, pupils may struggle to be systematic and not identify all options systematically. Correction: Spend time exploring the value of recording combinations within a simple table. Encourage checking, e.g. the amount of counters totals eight. Look for patterns and support children in spotting these.
