Year 4 have created Factor Reindeer. We used our knowledge of times tables to find the factors of a variety of numbers between 1-100. Some reindeer have a special antler spike when the same number is multiplied together – for example 25 have factors 1, 25 and 5. Santa sent us a special mission to find Factor Reindeer that only have 2 factors and these are called Prime Reindeer – they are very important and essential for Santa to pull his sleigh. Can you think of any Prime Reindeer?
