Students are practising mental math and sharing strategies for adding numbers accurately and efficiently. 

In this number talk, students were asked to add 7+3. Students independently used mental math to add the two numbers together, then we discussed the addition strategies (see photo below).

Next, students were given another question and asked how answering the first question might help solve this one:
7+5+3

We discussed the strategy of making ten to solve this question.

Finally, students applied the mental math strategy of making ten to this last question:
3+6+7
