Partition the numbers one to five in a systematic way
Lesson details
Learning outcome
I can partition the numbers one to five in a systematic way and know when I have found all the combinations.
Key learning points
- Know there are different ways to partition the numbers one to five.
- Know each of the numbers one to five can be partitioned in a systematic way.
- Use part-part-whole models to record the different combinations systematically.
- Use a table to record the different combinations systematically.
Keywords
Partition - Partition means to split up a whole into parts.
Part-part-whole model - A part-part-whole model is a pictorial representation that shows the whole and its parts.
Combination - Any way two or more parts can be put together.
Working systematically - Having an order to the way we work, identifying and using patterns.
Table - A way of showing information (such as numbers and descriptions), arranged in rows and columns.
Common misconception
When using patterns to identify combinations, it will be easy to make errors in recording.
Spend time exploring the value of recording combinations within a simple table. Encourage checking, e.g. the amount of counters totals 5.
Teacher tip
The first part of this lesson focuses on finding all possible combinations through trial and error. The second part encourages more systematic thinking, leading children to find all possible combinations quicker and check that none have been missed.
