Beat the Clock Age 3 to 5 Children use everyday language to talk about time, to compare quantities and to solve problems.

Becky spotted a different type of pattern: We found out that powers of 2 2, 4, 8, I wonder why? Then we discovered that the multiples of 5 can be written as 5 consecutive numbers. It's the same as the rule for 3 consecutive numbers.

We then made a conjecture that since it is true for 3 and 5, it would also work for 7, 9 and any other odd number. We tested it, and it worked. Arthur asked: Are there any other patterns? Can we explore the powers of two further? Is there a nice way to write certain numbers for example, every other even number as a sum of consecutive numbers? Ottilie suggested: Instead of adding, you could multiply the consecutive numbers, and see what patterns come up.

You could also only add consecutive even numbers, or only consecutive odd numbers. These things could all have something in common, or there could be a pattern between them, or nothing at all, maybe? Magnus asked: Is the rule that the powers of two can never be made always true? Can all numbers except the powers of two be made? Great questions!
