Focuses on six math standards that students rarely experience in the classroom in a multip-choice, timed-testing format. Each problem set (a page of three problems) has three levels of difficulty. The first, introduces the math concept, the second provides an opportunity for students to independently practice the concept and the third provides a more challenging application of the concept. Each also has an Extend the Thinking question that encourages students to either build on the information in the problem or to communicate their reasoning.
