In KS2 Year Six, children should be quite comfortable when dealing with number sequences in Maths. By now they should easily be able to recognise patterns in increasing or decreasing number sequences involving whole numbers, fractions and decimals. They will also be more familiar with odd and even numbers and should know the values reached when adding, subtracting or multiplying them together. They will now be exposed to sequences involving square, triangle and minus numbers.
Number sequences are lists of numbers that follow patterns. For example, triangle numbers increase by adding 1 then 2 then 3 etc... and square numbers increase by adding 3 then 5 then 7 etc... Learning to spot the patterns enables you to know which numbers are going to come next in any given sequence.
Can you spot sequences of square and triangle numbers? See if you can find the rules of these number sequences in this quiz for 10-11 year olds?
