This is nice mini SMARTboard lesson on teaching the three addition properties: commutative, associative, and zero.
Included are definitions, examples, and ways to help students remember.
There is also a fun sorting game included where the students match addition problems to their correct property.
It is aligned with grade 3 common core standard 3.NBT.2.
It can also be used in grade 4, as a review in the beginning of the year.
Thank you and enjoy!
