Title: Teaching Through Problem Solving

Teaching Through Problem Solving
• The Three Part Lesson

Presented by Sandra Jean Price Math
Coach Durham District School Board
2
• Problem solving is not only a goal of learning
mathematics but also a major means of doing so.
(NCTM, 2000, pg.52)

Before Activity
• prepare students for the lesson problem by
activating prior knowledge
• brief activity (5-10 minutes) that engages
students
• revisit a concept, procedure, or strategy that is
related to the learning goal
• revisit a previous problem
• have students revisit how they solved a previous
problem
• have students solve a simpler/smaller problem
that evokes prior knowledge, skill, and/or
strategy
• have students share their thinking
• ensure all expectations for products are clear

Before Activity
• Show 1/2 of 1/3 using as many different
strategies as you can.

6
During Activity
• students are actively involved in solving the
problem, working in small groups, pairs, or
individually
• students talk, read, and write their mathematical
thinking
• let go
• teacher circulates among the students, observing
and assessing
• teacher might pose questions to provoke further
thinking or have other students explain their
plan for solving the problem, but does not give

There was a jar of cookies on the table. Suhoung
so he atehalf of the cookies. Angela came along
and saw the cookies. She thought they looked
good so she ate a third of what was left in the
jar. Carrie came by and took a fourth of the
decided to take six of them to work to eat on his
break. When Heather came home she noticed there
were only three cookies left. How many
cookieswere in the jar to begin with?
During Activity

After Activity
• student sharing of solutions facilitated by
teacher (bansho, congress, gallery walk)
• students can hear and analyse their classmates
mathematical thinking
• students learn to discern similarities and
differences between the mathematics, methods, and
strategies inherent in the student solutions,
allowing them to make connections between their
own mathematical ideas and the ideas of others
• teacher helps students to see connections between
solutions and strategies

9
After Activity
• Share different strategies and answers through a
congress, gallery walk or bansho.
