Lesson details
Key learning points
- To find one-half of a number you split it into 2 equal parts
- One-half of a number can be written as an equation using fraction notation.
Keywords
One-half - One of two equal parts of a whole.
Common misconception
Children may try to make a group of 2 objects rather than share into 2 equal parts.
Use the stem sentence 'the whole group of _ has been divided into 2 equal parts and there are _ in each part' alongside concrete objects so that the children can experience dividing different numbers of objects into 2 equal parts.
