Students love moving around the room answering these questions on their answer sheets and clipboards. There are many different types of problems to help see where your students are in their understanding of using the different strategies. There are word problems, missing addend problems, some subtraction problems, visual pictures, and problems where they have to write out the number sentence. This is a great way to start your students with fact fluency. These are the key strategies that students need to master. Each strategy has 32 cards.
