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
![Page 3: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/3.jpg)
Teaching Through Problem Solving
• 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.
A good instructional problem:

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)
![Page 5: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/5.jpg)
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
Identify the Curriculum Expectations
![Page 6: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/6.jpg)
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.
Determine the Big Ideas
![Page 7: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/7.jpg)
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.

3-Part Lesson – An Algebra Example
![Page 9: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/9.jpg)
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’.
![Page 10: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/10.jpg)
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
![Page 11: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/11.jpg)
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
![Page 12: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/12.jpg)

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.
![Page 14: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/14.jpg)
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.
Part 2 – During/Action/Working On It
![Page 15: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/15.jpg)
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
![Page 16: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/16.jpg)
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.

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.
![Page 19: 3-Part Lessons](https://reader036.fdocuments.net/reader036/viewer/2022062521/5681694f550346895de0f0aa/html5/thumbnails/19.jpg)
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.
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

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 studentswho are often labelled as strugglers feel inferior.

Choose the pro or con side and make your argument:The best way to add mixed numbers is to make them into equivalent improper fractions.
Think of a situation where you would add fractions in your everyday life.
Make up a jingle that would help someone remember the steps for subtracting mixed numbers.
Someone asks you why you have to get a common denominator when you add and subtract fractions but not when you multiply. What would you say?
Create a subtraction of fractions question where the difference is 3/5. • Neither denominator you use can be 5. • Describe your strategy.
Replace the blanks with the digits 1, 2, 3, 4, 5, and 6 and add these fractions:[]/[] + []/[] + []/[]

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