Subtraction up to 100

This week for maths we had to do subtraction to 100 for mr wongs maths group using the basic facts boxes . This had to be made inderpenditly . We also had to do this by using our place value houses to try and get the right answer . After we got the hang of doing it we also had to write down some of the takeaways in our books and try to solve them using our books . We used the place value house trying to solve these takaways because we have been using place value houses the past few weeks .
