Middle School Math Strategies: Teaching the Standards in

1. Middle School Math Strategies:Teaching the Standards in Lois Coles 8th Grade Brentwood Middle School loisc@wcs.edu

2. NCTM Process Standards Problem Solving Communication Connections Reasoning and Proof Representation

3. TN Process Standards Use mathematical language, symbols, and definitions while developing mathematical reasoning. Apply and adapt a variety of appropriate strategies to problem solving, including estimation, and reasonableness of the solution. Develop independent reasoning to communicate mathematical ideas and derive algorithms and/or formulas. Move flexibly between concrete and abstract representations of mathematical ideas in order to solve problems, model mathematical ideas, and communicate solution strategies. Use mathematical ideas and processes in different settings to formulate patterns, analyze graphs, set up and solve problems and interpret solutions. Read and interpret the language of mathematics and use written/oral communication to express mathematical ideas precisely. Recognize the historical development of mathematics, mathematics in context, and the connections between mathematics and the real world. Use technologies/manipulatives appropriately to develop understanding of mathematical algorithms, to facilitate problem solving, and to create accurate and reliable models of mathematical concepts.

15. What is a Socratic Seminar? Socratic named for Socrates, a classical Greekphilosopher470-399 B.C who developed a Theory of Knowledge. He was convinced that the surest way to attain reliable knowledge was through the practice of disciplined conversation.� He called this method dialectic. Di-a-lec-tic (noun) means the art or practice of examining opinions or ideas logically, often by the method of question and answer, so as to determine their validity.

16. Procedure Respect one another's opinions Avoid interrupting, but there is no need to raise hands Address classmates by name Take notes Comments should address the topic and not digress Points of disagreement are settled among participants; the teacher is not a resource Sit in a circle so that everyone can be seen (or a semicircle at the board)

17. Why have a Socratic Seminar in Math?

18. Research �Socratic seminars (encouraged) students to assume responsibility for reasoning and communicating convincingly about mathematics�helped the teacher assess students� conceptual understanding of functions�� (Koellner-Clark) �We saw repeatedly that when students discussed their ideas with others, they continued to revise, refine, and improve them.� (Borasi 1992; Moschvich 1998)

19. Socratic seminars Involve all kids Find situations that use math but don�t have �right� answers Get kids away from computation-based math problems Build a thinking and reflecting community of learners

20. Rundown of Rules EVERYONE participates No idea is a bad idea Think outside the box and don�t be afraid to be creative Show respect - No criticism allowed *No right/wrong answers *Acknowledge others� comments Student-Led!

21. Practice Seminar:Skin Scare Imagine for one moment that you have been involved in a car accident. There was a fire and you were burned. You were taken by ambulance to the emergency room and are being treated by several doctors.

22. Skin Scare You are fully aware of what is going on around you, but as is often the case, no one is telling you what is happening. You have to gather information from what you hear and observe. You know you have been given medication, so you cannot judge the extent of your injuries by the amount of pain you feel. You know that you are burned, but cannot tell how badly.

23. Skin Scare You hear the doctors talk about skin grafts and then an order is made for 800 in2 of skin for the procedure. At this point, how serious are your injuries? Do you think, �Oh good, they will take care of me� or �Oh NO! I�m in trouble�? Why?

24. Student Comments �When are we going to have another discussion? I love those!� �I�m glad that there aren�t right answers and that there are lots of ways of looking at the problem.� �It�s fun to see how what we are studying connects to the world.�

25. Brainstorm ideas for questions� Open ended, but not huge (can tackle in one class period) Problems that can have a variety of approaches Problems that have less computation and more reflection/application Problems that can have very different strategies-create debate!

65. What is pi? Pi, which is denoted by a Greek letter, is the most famous ratio in mathematics, and is one of the most ancient numbers known to humanity. Pi possibly first entered human consciousness in Egypt. The earliest known reference to pi occurs in a papyrus scroll, written around 1650 BC by a scribe named Ahmes. Around 200 BC, Archimedes of Syracuse found that pi is about 22/7 (Greeks did not use decimals). The first person to use the Greek letter for the number was William Jones, an English mathematician, who coined it in 1706.

84. Georges-Louis Leclerc, Comte de Buffon Comte de Buffon discovered this result in the 16th century: if you drop a needle on a grid of parallel lines which are spaced the length of the needle apart, the probability that the needle will land on a line is 2/p.

85. Buffon�s Needle Experiment:It�s Probably Pi 1. Drop a bunch of toothpicks on the parallel lines. Write down the number of toothpicks you dropped in "Number of Drops" column. 2. Count the number which crossed a line and write it in the "Number of Crossings" column. 3. Add your number of drops to the "Cumulative Drops" and write the total on the data sheet. 4. Add your number of crossings to the "Cumulative Crossings" and write the total on the data sheet. 5. Calculate a new value for p by dividing the "Cumulative Drops" by the "Cumulative Crossings" and multiplying your result by 2.
