I don't know about you, but I find that the math series that my district uses as our main resource does not do the best job of meeting the standards. They are aware of this, and have always encouraged us to move away from the series if/when it's not meeting our needs. Our Math Supervisor (amazing published author Bob Krech, lucky us!!!) has always made sure that we teach the curriculum, not the series. He often reminds us that the series is one resource to help us get there.
One standard that our series doesn't even touch is 1.OA.7:
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.
So here is a Thanksgiving Equal or Not? freebie I created to practice that skill. Click on the link or any of the pictures to grab it. Enjoy!
