3-Part Lessons

1. 3-Part Lessons Jane Silva Instructional Leader Mathematics/Numeracy, K-8 SW

2. Teaching Through Problem Solving Using a Three-Part Lesson Model • allows teachers to develop rich and engaging tasks • naturally embeds the mathematical processes expectations • leads to conceptual understanding and more meaningful connections

3. Teaching Through Problem Solving A good instructional problem: • builds on students’ prior knowledge and skills; • considers a key concept or big idea; • has a meaningful context; • has multiple entry levels (differentiation); • solution is not immediately obvious; • may have more than one solution; • promotes the use of one or more strategies; • requires decision making; • may encourage collaboration.

4. Components of a 3-Part Lesson • Part 1 (Before/Getting Started/Minds On) • Part 2 (During/Working On It/Action) • Part 3 (After/Reflect and Connect)

5. Identify the Curriculum Expectations What are/is: • the content and process expectations this lesson addresses for your grade level; • the prior knowledge and skills students would have learned in the previous grade; • the overall and specific expectations this problem addresses for the next grade level; and • expectations/connections to other strands. Ex: Gr. 8 - solve and verify linear equations involving a one-variable term and having solutions that are integers, by using inspection, guess and check, and a "balance" model

6. Determine the Big Ideas Big Ideas • The broad, important understandings that students should retain long after they have forgotten many of the details of something they have studied. Ex: Any pattern, algebraic expression, relationship, or equation can be represented in many ways. The principles and processes that underlie operations with numbers and solving number equations apply equally to algebraic situations.

7. Determine the Learning Goal Learning Goals: • Consider the curriculum expectations and big ideas • Describe what students are expected to learn • Provide students with a clear vision of where they are going • Focus effective teacher feedback on learning • Develop students’ self-assessment and self-regulation skills Ex: I will be able to create equations and use different strategies and representations to show that the equations are true.

8. 3-Part Lesson – An Algebra Example

9. Part 1 - Before/Getting Started/Minds On • relates to the day’s lesson goals and problem; • activates prior knowledge; • assesses students’ prior knowledge and skills; • engages students/develops a context; • checks for students’ understanding for ‘during’.

10. Part 1 - Before/Getting Started/Minds On • 5-10 minutes • Activating students’ mathematical knowledge and experience that is directly related to the mathematics in the lesson problem • Use a smaller problem similar to the previous known problem • Use student work responses for class analysis and discussion to highlight key ideas and/or strategies

11. Part 1 • Sort and sequence the equation strips. Ex: Opportunity for Differentiation - Parallel Questions • Only 1 equation in the envelope • 2 equations in different colours • 2 equations with different variables • Partially completed solutions • 3 or 4 equations in the same colour

12. Part 1

13. Part 2 – During/Action/Working On It Students are: • actively-engaged in problem solving; • making hypotheses and conjectures; • choosing methods, strategies, and manipulatives; • discussing mathematical ideas with others; • constructing their own knowledge; and • developing perseverance.

14. Part 2 – During/Action/Working On It Teacher is: • scaffolding students’ learning; • conferencing with small groups or individual students; • observing and noting student/group strategies, mathematical language, and models of representation; • engaging in Assessment FOR Learning.

15. Part 2 – During/Action/Working On It • 15-20 minutes • Understand the problem, make a plan, carry out the plan • Students solve the problem individually, in pair, or in small groups • The teachers support student understanding and assesses for learning

16. Part 2 Write an equation with 4 different numbers and the variable x. At least 2 numbers must be from this list: 4 13 100 1000 Show that your equation is true.

17. Assessment FOR Learning: Observation and Interview Template

18. Part 3 – After/Reflecting and Connecting/ Consolidation and Debrief Students are: • reflecting on their own thinking (meta-cognitive skills) and the thinking of other students; • communicating problem solving strategies, methods, and solutions to their peers; • consolidating the learning of new concepts.

19. Part 3 – After/Reflecting and Connecting/ Consolidation and Debrief Teacher is: • deciding which group’s strategies, methods, or solutions should be presented to highlight the mathematical thinking and to develop the mathematical understanding of all students related to the problem and lesson goals; • facilitating the learning by annotating and labeling work samples; • asking for clarification or having students summarize for partners or the whole group the thinking of the presenting group; and • engaging in Assessment FOR Learning.

20. Part 3 – After/Reflecting and Connecting/ Consolidation and Debrief • 20-25 minutes • Teacher selects 2 or more solutions for class discussion and decides which solution to share • Teacher organizes solutions to show math elaboration from one solution to the next, towards the lesson goal • Student authors explain and discuss their solutions with their peers • Teacher mathematically annotates solutions to make mathematical ideas, strategies, tools explicit

21. Part 3 What thinking did you use to create your equation? Which strategies did you use to show that your equation is true?

23. Differentiation Strategies

24. Goal The goal is to meet the needs of a broad range of students, but all at one time– without creating multiple lesson plans and without making students who are often labelled as strugglers feel inferior.

26. Cube Powers Face 1: Describe what a power is. Face 2: How are powers like multiplying? How are they different? Face 3: What does using a power remind you of? Why? Face 4: What are the important parts of a power? Why is each part needed? Face 5: When would you ever use powers? Face 6: Why was it a good idea (or a bad idea) to invent powers?

27. Menu Fractions, Percent and Decimals Appetizer (Everyone): • What does the denominator and numerator tell you? Main dish (Choose 1): • You want to estimate 20/30 as a percent. Describe your thinking. • You want to estimate 0.3 as a fraction. Describe your thinking. Side dishes (Choose 2): • Draw a picture to show why 0.4 and 6/15 are equivalent. • Draw a flow chart to show how someone should proceed to convert a fraction to a percent. Dessert(if you wish) • A decimal begins 0.24…. but then it continues. What do you know about the fraction it could represent. • Alicia says that the only fractions that are whole numbers of percents have denominators of 2, 4, 5, 10, 20, 25, and 50. Do you agree? Explain.

31. Learning Centers Surface Area Station 1: Simple “rectangular” or cylinder shape activities Station 2: Prisms of various sorts Station 3: Composite shapes involving only prisms Station 4: Composite shapes involving prisms and cylinders Station 5: More complex shapes requiring invented strategies

32. Open Questions

33. Strategies for Creating Open Questions • Start with the Answer • Closed: √64 = • 8 • Open: An irrational number is about 8. What might it be? • √65 • √64 • 2π + 2 • 8/3 π

34. Strategies for Creating Open Questions • Ask for similarities and differences • Closed: Describe each term in the equation y = 3x - 2 • Open: How are these two equations alike? How are they different? y = 3x – 2 y = 6x - 4

35. Strategies for Creating Open Questions Replace a number with a blank Closed: A rectangle has a length 3cm and a width 4cm. What algebraic expression can describe features of the rectangle? Open: A rectangle has a length __cm and a width 4cm. What algebraic expression can describe features of the rectangle?

36. Parallel Tasks The idea is to use two similar tasks that meet different students’ needs, but make sense to discuss together.

37. Parallel Tasks - Examples • Choose Plan 1 or Plan 2. • How much would 250 minutes cost? • Provide an equation. Cell phone Plans

38. Parallel Tasks - Examples Numeration and Number Sense Task A: 1/3 of a number is 24. What is the number? Task B: 2/3 of a number is 24. What is the number? Task C: 40% of a number is 24. What is the number?

39. Parallel Tasks - Examples Task 1: Find the equation of a line to complete this parallelogram: y = 8 y = -3x + 12 y = 2 Task 2: Find the equation of a line to complete this right triangle y = -2x + 8 y = 1/3 x

40. How to Create Parallel Tasks Think about the underlying big idea. Think about how it can be made more accessible to struggling students. Alter your original task to allow for that accessibility.
