This is a set of the 12 addition and subtraction problem types required by Common Core Standards. Each poster names the type, shows a concrete mode, an equation, and the accompanying word problem as an example of that problem type.
I use these as a bulletin board set, and as a whole group and intervention group teaching tool. Common Core asks us to explain to the students the why and the what concerning what they are learning, and having these types displayed and explicitly taught will do just that!
Designed with different color poka dot borders and monsters as models.
