Dear Miss Scarrott,

We think that the question is false because any number can be divided at least once. We founded out how to do factors of different numbers. You need to use multiplication when doing factors of different numbers. For example, 18 and 1 and also 9 and 2 are factors of 18

Today I found out what prime and composite numbers are I had heard of it before but never knew what they were. My definition would be “prime numbers are numbers that have two factors 1 and itself e.g. 3, 2.

Dear Miss Scarrott,
Today Ke Bre and I learned about prime and composite numbers. We learned that the prime numbers can only be divided by 1 and themselves, and a composite is more than two factors. We also enjoyed the game, it taught us new things about prime and composite numbers.

Dear Miss Scarrott,
Today we found out that more about prime and composite numbers as well as square numbers.
We clarified our understanding about prime numbers being a number that has 1 and itself as a factor. For example, 7 is a prime number because the factors of it is only 1 and itself. Another example is 29, because the factors of it is only 1 and itself.

Dear Miss Scarrott’
We learnt about square numbers and how they work. We also learn what a prime number is and how they can only be multiplied by it’s self and one.
Some square numbers are 2×2=4 3×3=9 6×6=36 7×7=49

Dear Miss Scarrott,
Today I found that no one really know s if the number 1 is a prime number. Some people say it’s also a squared number because 1×1=1 and it only has 1 factor instead of 2.

Dear Miss Scarrott,
Thank you for today’s lesson, we both learnt something new that we didn’t quite understand fully before.
Day Day and I learnt that composite numbers has to be at least more than 3 factors and it makes a square array. We also learnt that prime numbers can only be divided by one and it’s self as factors ONLY.
Our definitions for prime numbers, composite and square numbers is
Prime numbers: can only be divided by one and itself as factors only.
Composite numbers: needs at least 3 factors to be a composite number
Square numbers: a number that can be arrange into an array
We enjoyed this session!
