This is a powerpoint that shows pictures of the tens and units equipment that you often find in school. It explains what a ten is and what a unit is, and then has some examples of how 2 digit numbers are broken down- e.g. number 33 is 3 tens and 3 units etc. The last slide is just to show the work that I had set the class to do that day- obviously this can be altered to suit your own needs. I hope this helps someone!
