Elder class have enjoyed creating various arrays, using counters, in order to deduce all the factor pairs of given numbers. As the children talked about their findings, they used mathematical vocabulary such as multiple, factors and product. We noticed that some numbers allowed us to create square arrays eg, 16, 25 and therefore these numbers are square numbers. Some of us learnt about prime numbers and found prime numbers only allow one array of 1 x the given number. Super investigating Elder class!
