In KS2 Maths Year Six, kids are getting really good at number sequences. They can easily see patterns in numbers going up or down, including whole numbers, fractions, and decimals. They know odd and even numbers well and understand what happens when you add, subtract, or multiply them. Now, they're discovering sequences with square, triangle, and minus numbers!

Number sequences are like magic lists of numbers with patterns. For example, triangle numbers go up by 1, then 2, then 3, and so on. Square numbers go up by 3, then 5, then 7, and so on. Spotting these patterns helps you figure out the next numbers in the sequence.

Can you find square and triangle number sequences? Test your skills in this quiz for 10-11 year olds!
