Exploratory Algebra Class

1. The Many Colors of Algebra – Engaging Disaffected StudentsThrough Collaboration and Agency.

2. Exploratory Algebra Class

3. Exploratory Algebra Class • Algebra as a problem solving tool • Integrating mathematical practices with algebraic content

4. The Students - ethnicity: • 39% Latino • 34% White • 11% African-American • 10% Asian • 5% Filipino • 1% Native American

5. The students - achievement (prior math class) • 40% A or B • 20% C • 40% D or F • Disaffected?

7. Reasons for attending summer school? • 10% involved in choice • 90% ‘made’ to come by parents / teachers

8. 4 Teaching principles • Engage students as active and capable learners • Teach mathematical practices – reasoning, organizing, representing, generalizing • Develop a collaborative, mathematical community • Give opportunities for student voice

9. Active and Capable Learners • Heterogeneous groups • Agency • Andrew Pickering • The ‘dance of agency’

10. Mathematical Practices • exploring, orienting, representing, generalizing, questioning, organizing mathematical thinking

11. Develop a collaborative, mathematical community • Groups • Pairs • Student presentations and discussions eg four 4’s

12. Student Voice

14. Research Data • Summer school applications • Lesson observations • Student surveys & reflections • Student interviews – 35 during the summer, 15 in the fall • Class materials – posters, work • MARS assessments • Grades in fall and winter

15. Results • Achievement • Engagement & Enjoyment • Future Success

30. Collaboration & Agency

31. The silent math class “For the past year, math year was the hardest because you’re not supposed to talk, you’re not supposed to communicate.” “In other classes it used to like be hard doing my work cause it used to be so boring…and I used to get frustrated and stuff and like right here we get to do group work and we get to talk and stuff and that like helps it not be so boring.”

32. Increased access to understanding “in normal school you don’t get to do this, but it helped me understand things more” “it helps me see how they see it and to see if I could understand it” “I kind of build on other people’s ideas, I really do respect what other people say.”

33. Multiple Methods “I used to use only one way the teacher taught me and not really understand it. Now I use different ways until I get it.” “When I don’t know how to solve a problem the way the teacher does it, I have other ways to solve it.”

34. Mathematical Seeing “When we would see the problem in different ways we would understand it better.” “It’s like the way – the way our schools did it is like very black and white, and the way people do it here, it’s like very colorful, very bright. You have very different varieties you’re looking at. You can look at it one way, turn your head, and all of a sudden you see a whole different picture.

35. Mathematical tinkering “I have learned that after finding a pattern you can stretch it in many ways instead of just staring at it. I have learned to think beyond the answer to the problem ” “Generalizing helped me to look beyond the problems and make challenges for myself” ‘When I’m done, I think of something harder to do”

36. Common Core Standards: Mathematical Practices. • Make sense of problems and persevere in solving them • Reason abstractly and quantitatively • Construct viable arguments and critique the reasoning of others • Model with mathematics • Use appropriate tools strategically • Attend to precision • Look for and make use of structure • Look for and express regularity in repeated reasoning

37. Supporting Practices • Organisation • Taking a smaller case • Representation

38. How many squares are on a chessboard?

39. “I have learned to organize my work – write it all down” “I learned to organize my work by making T-tables, making charts, also I learned that I should label important information in directions etc” Organizing

40. Trying a smaller case “Patterns were very helpful because sometimes the question was asking about a huge number, so then I would just start with some smaller numbers, find a pattern and predict the answer without just taking a lot of time and effort to do the one big problem”

41. Beans and Bowls. How many ways are there to arrange 3 beans into two bowls?

42. Video 1 – teaching organizing, representing, generalizing … through girl and ways and beans

43. Representing Answers to ‘What have you learned’: “I learned to say what I’m thinking (in words).” “taking notes, to remember info and drawing pictures to see what’s going on” “I learned to see patterns a lot better and how to understand how it gets bigger (or smaller).”
