Getting confident with place value

I thought I would share a bunch of questions I have been using with my low attaining Year 7 class. These guys are pretty good at the process of column addition and subtraction but were not confident with place value such that they could immediately answer a question like this one:

What number is a thousand more than 17407?

I have been dropping one of these into our starters every lesson for the last couple of weeks and they now “get it”.  The next step is to carry over to the next place value, for example:

What number is eighty more than 1843?

We have also tried subtraction, for example:

What number is 500 less than 1935?

Moving on from this I have been using questions like these:

These step up in difficulty quite considerably I think.  I will be using ones like the first few and see how they get on before looking at Qu 7 onwards.

You can access these on this Powerpoint slide. Clicking on the boxes reveals the answer beneath.

  1. Those 10 extension questions are great for flipping the problem around to properly test for understanding. They can even lead to discussions revolving around infinity on the last few questions, what a great discussion to have!
    Thanks for sharing!

  2. No, I don’t think I would. And I probably would not use them all in one go as I have presented them here. If I have to think about the question then I can’t expect my pupils to answer them “fluently”. And the last 4/5 I have to think about quite a bit!
