This includes all of the math common core standards for second grade written into "I Can" statements so that the students may understand what they are learning. Each card contains a simple example of what the standard means in order for the students to have a visual to go with those vocabulary words!
In my classroom I have a space entitled "What are we learning?" where the cards will be interchanged with what we are covering at the time. Each time a new standard is introduced I cover it with the class, including the simple example, and place it on the board.
I hope you are able to use these! Please message me if you have any questions!
