Coming soon we have another in our series of rounding larger numbers to the nearest million. This page will look in particular at the world’s oceans and the numbers involved have already been rounded to the nearest 1 000 sq km.
We will also be publishing a snappy little worksheet to check that children can add on from 2-digit numbers to make 50. There are several different mental strategies that can be used, but the most efficient is usually to count on to the next whole ten and then count on in tens to 50.
Doubling 2-digit numbers can be quite easy or fairly tricky; it all depends on the numbers, so look out for a page on doubling next week.
