PRINCIPLES OF LEARNING Principle One: Building on Prior Knowledge Building on Prior Knowledge Principle Two: Understanding requires factual knowledge and conceptual framework Understanding requires factual knowledge and conceptual framework Principle Three: Metacognition

Principle One Students come to the classroom with preconceptions about how the world works. If their initial understanding is not engaged, they may fail to grasp the new concepts and information that are taught or they may learn them for purposes of a test but revert to their preconceptions outside the classroom.

Principle Two Achieving goals in mathematical understanding requires teachers to develop students knowledge networks, address students learning paths, and use multiple methods. This suggests the importance of conceptual understanding, procedural fluency, and an effective organization of knowledge.

Principle Three Metacognition, getting students to think about their thinking, can help students learn to take control of their own learning by defining learning goals and monitoring their progress in achieving them.

Another Problem I went to the store and bought the same number of books as records. Books cost two dollars each and records cost six dollars each. I spent \$40 altogether. Assuming that the equation 2B+6R=40 is correct, what is wrong if anything, with the following student reasoning? 2B+6R=40, since B=R, I can write 2B+6B=40, then 8B=40. This last equation says 8 books is equal to \$40. So, one book costs \$5.2B+6R=40, since B=R, I can write 2B+6B=40, then 8B=40. This last equation says 8 books is equal to \$40. So, one book costs \$5.

BIG MATHEMATICAL IDEA Goal is to transition students from proportional models to direct variation models. Goal is to transition students from proportional models to direct variation models. rational numbers proportional relationships direct variation models linear functions rational numbers proportional relationships direct variation models linear functions

BIG IDEAS - NCSM A ratio is a multiplicative comparison of quantities A ratio is a multiplicative comparison of quantities Ratios give relative sizes of quantities being compared Ratios give relative sizes of quantities being compared Ratios can be expressed as units by finding an equivalent ratio where the second term is one. Ratios can be expressed as units by finding an equivalent ratio where the second term is one.

BIG IDEAS – NCSM, continued A proportion is a relationship between relationships. A proportion is a relationship between relationships. If two quantities vary proportionally, the ratio of corresponding terms is constant. If two quantities vary proportionally, the ratio of corresponding terms is constant. If two quantities vary proportionally, the constant ratio can be expressed in lowest terms ( a composite unit) or as a unit amount; the constant ratio is the slope of the related linear function. If two quantities vary proportionally, the constant ratio can be expressed in lowest terms ( a composite unit) or as a unit amount; the constant ratio is the slope of the related linear function. Ratio is a reflectively abstracted constant ratio. Ratio is a reflectively abstracted constant ratio.
