Understanding Addition

We finished our topic on understanding addition on Friday. I think that most, if not all my students understand the concept of addition after all the different activities we did.

We use Envision Math for our curriculum and that program starts with ways to make 6 and 7. So we did a "bears in a cave" activity which I learned from my colleagues.

There are six bears in all. Zero bears are outside the cave...
So there are 6 bears inside the cave!
There are 6 bears in all. One bear is outside the cave.
So there are 5 bears inside! :)
Then we moved on to ways to make 7, 8, and 9. 

Found the "Nine Ways to Make 8" here through pinterest. I created worksheets for making 6, 7, 8, and 9.

Finally, we talked about joining stories and writing addition sentences. Remember our penguins from our Animals unit opener? Well we finished up our penguins by writing our addition stories and adding the fish on there. They are now up on our hallway bulletin for all the see. I've already received compliments from the other teachers on how cute they look! Get the templates for this from Erica Bohrer's First Grade

Not sure why this kid wrote penguin on his penguin. Haha.
Super cute! Now, moving on to understanding subtraction! Time to search pinterest for some more cute ideas! :)
