WALT: Round the 7-digit number to the nearst 10 ,100,10000, 10,000, 100,000
1.000,00,
The key vocabulary we’ve been focusing on is estimate, rounded to the nearst…….approximate approixmately
This week we have using number lines to help us to determine if the number we were interested in was being rounded up or down. we would identify the digit that we are interested in and look at the digit to its right. for example the digit 2,973,190. if we were to round to the neasrt 100 then the digit 3 and its pair 1 in the hundreds coulumn are the the numbers we are interested in. 31 is closer to 30 so , we would say 2, 973,190 is approixmately equal to 2,973,000.
It is essential to know the plave value. at level 4 we are expected to be able to round up to 10 million
we had help from out teacher and now we know what we are doing.
Here is a video explaning my thinking
