Over the next few months we will be concentrating on creating the most up-to-date resources to cover the KS2 Maths Reasoning Papers. This week we have published a set of pages on counting in steps of powers of 10. (The content domain reference is 5N1: Year 5 number statement 1.)
This might sound relatively easy but a couple of points
a. the sequences given are often in descending order
b. the number to be found often crosses the ten thousand or hundred thousand boundary, such as in this question:
The numbers in this sequence decrease by the same amount each time.
503,702 502,702 501,702 500,702
What is the next number in the sequence?
To be correct a child must firstly work out how many the number is decreasing by each time and then successfully subtract this from the last number in the sequence. Tricky for those not confident with working with larger numbers.
