  • It looks great for checking understanding of tens and ones. The pictures are attractive and will make the activity more fun. The only problem is the last question! I hope it's not me being thick but I don't think it works. It says 'What number can you add to any number and it will change the value of the 100s, 10s and ones?' I found quite a few where it doesn't work - 100+99=199 Value of 100s not changed. 200+99=299 Again the value of the 100s stays the same. Obviously it will be the same for 300, 400, 500, 600 etc. Also 101+99= 200 - Value of 10s not changed.102 + 99= 201 Value of 10s not changed. As i said - maybe I've missed the point but if it is a mistake It's good to know before giving to the class!!
    All the same, I love the resource - I'll just miss out that last one! Thanks.

    • Surely if you add 2 to 99 it changes the 100s, 10s, and units? 2 99=101, it works for any 3 digit number wit 99 as the 10s and units and can have any digit added to it 1-9 and the 3 digits.
