Identify equal parts when they do not look the same
Lesson details
Learning outcome
I can identify equal parts when they do not look the same.
Key learning points
- Equal parts do not have to look the same.
- Equal parts of a whole can be different shapes.
- A whole can be made from equal parts that are different shapes.
Keywords
Whole - The whole is all the parts or everything, the total amount.
Part - A part is some of the whole.
Equal - We say that two or more things are equal if they have the same quantity or value.
Unequal - We say that two or more things are unequal if they do not have the same quantity or value.
Common misconception
Some children may not be fully aware that two shapes can have the same name but be differently shapes. For example, there are several different types of triangle.
Maintain a real focus on 'What's the same and what's different?'. Don't shy away from any questions or misconceptions about categories of shape, use them to further any learning.
Teacher tip
Doing as well as seeing is essential here. Get the children cutting and proving wherever possible. It's also worth considering the use of a visualiser to demonstrate the cutting and proving to begin with. Also, you could keep some of the puzzles for intervention tasks or the wet-break cupboard.
