Next week, the children will be looking at multiplication and division in maths. They will be:

-Multiplying and dividing numbers mentally drawing upon known facts.

-Know and use the vocabulary of prime numbers, prime factors and composite (non-prime) numbers

-Establish whether a number up to 100 is prime and recall prime numbers up to 19.

What are prime numbers?

An introduction to prime numbers, composite numbers and factors. We learn that the number 1 is neither prime nor composite, and the idea of factor pairs is introduced. We look at how to decide whether a natural number is prime or composite by looking for proper factors.

Multiplying and Dividing

The children will multiply 2-digit numbers by x2 to x12, using the following method: 16 x 7 = (10 x 7 = 70) + (6 x 7 = 42) = 70 + 42 = 112.

They will also divide 3-digit numbers by x2 to x12, using the following method: 147 ÷ 7 = (140 ÷ 7 = 20) + (7÷ 7 = 1) = 21
