One of two equal parts of a whole. / To divide into two equal parts.

Explain how a division equation with 2 as a divisor is related to halving

Maths

In this unit pupils will double and halve 2 digit numbers. They will learn to use times table facts to find the quotient for 2x 5x 10x tables. Pupils will learn each part of a division equation and how they can be interchanged.  In the future unit pupils will solve multiplication and division problems using knowledge of the relationships between the 2x 4x 8x tables.

In the prior unit pupils learned how a multiplication equation with 2 as a factor related to doubling and how a division equation with 2 as a divisor related to halving. They explained the relationship between factors and products. In this unit pupils will double and halve 2 digit numbers. They will learn to use times table facts to find the quotient for 2x 5x 10x tables.
