Explain how a division equation with 2 as a divisor is related to halving
Lesson details
Learning outcome
I can explain how a division equation with 2 as a divisor is related to halving.
Key learning points
- Halving is dividing into two equal parts.
- Halving is the same as dividing by 2
- Halving can be used for a division equation where 2 is the divisor.
- We can use known halving facts when the divisor is 2
Keywords
Divisor - The divisor is what we are dividing by.
Half/ Halving - One of two equal parts of a whole. / To divide into two equal parts.
Common misconception
Children may make errors when halving 2-digit numbers.
Recap strategies for halving from previous units prior to the lesson so that the process of halving numbers does not take over the focus of this lesson.
Teacher tip
Further visual representations can help children to see that 'dividing by two' is the same as 'finding a half of'. Physically manipulate objects in this way in your environment. Securing this basic understanding is vital for later learning, including surrounding fractions.
