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 explain that items can be compared using length and height, mass and volume/capacity. They will compare sets of objects using equality/inequality symbols. Pupils will also explore part-part-whole relationships with representations.
Lesson Summary
You will learn to explain that a whole can be split into two or more parts.
Key Notes
- A whole can be split into two or more parts in different ways.
- The parts may look different.
- Each part will be smaller than the whole.
- The parts can be combined to make the whole.
Vocabulary To Learn
- whole: All of something. Complete.
- part: A piece of a whole.
- split: To break up a whole into parts
- combine: To put parts together to make a whole
Common Mistakes To Avoid
- Children may think that smaller wholes are only a part and that parts all have to look the same.
