Year 3 - Addition and Subtraction

Year 3 are exploring the connection between addition and subtraction and solving addition and subtraction problems using a range of efficient mental and written strategies.

They started the unit with a class discussion on Addition. Using the 'think, pair, share' strategy, the students shared their mathematical knowledge and understandings. 

What strategies do you use when completing addition problems?
