Primary 5 have been learning about Factors, Multiples, Square and Prime numbers in our numeracy session today.

“Factors are numbers that divide equally into another number with no remainders.” – Niamh

Factors can be shown in pairs.

The factors of 12 are:

• 1 and 12    1 x 12 = 12
• 2 and 6     2 x 6 = 12
• 3 and 4    3 x 4 = 12    –Matthew

We created factor bugs to show our understanding.

Bugs have a target number in the middle and you have to give the bugs legs which are pairs of factors. The antennae of the bugs are always 1 and the target number.

“If a bug only has antennae and no legs it is a prime number- this means it can only be divided by 1.” –Isla

“19, 13 and 7 are examples of prime numbers.”- Sarah

Some bugs can have a tail which means the number is a square number.

“9 is a square number and would have a tail because 3 x 3  is 9”- Ralph

The skills we used for this task were problem solving skills, multiplication and division skills, listening skills and memory skills. Mrs Stephen was very impressed how hard we worked today! Keep it up Primary 5 😊
