Contextual Problem-PosingSeeing The Mathematics Around Us
I’m Kate. I’m a primary educator, with a passionate interest in how the practice of
contextual problem-posing can increase the engagement, confidence and enjoyment
found in mathematics for both students and teachers alike.

Problem-Posing in Practice
– Georg Ferdinand Ludwig Philipp Cantor (1867)
“In mathematics the art of proposing a question must be held of higher
value than solving it.”
What is Contextual Problem-Posing?
What do I mean by ‘contextual problem-posing’?
The development of a problem within a given
context
What do I mean by ‘contextual problem-posing’?
Context:
- Physical Setting- Idea or Question- Artifact
What do I mean by ‘contextual problem-posing’?
Meaningful, relevant, real
Real ≠ Real Life
Open, context given, content given, or content & context given
Context Given
Pose as many mathematical problems as you can about
the book we just read.
Context Given
What mathematical questions do we need to answer in
order to plan a class party?
Content Given
Pose as many problems as you can involving division with a
remainder.
Context & Content Given
Pose as many multiplication problems as you can about
designing a treehouse.

“A good problem is something you don't know how to solve. That's what makes it a good
puzzle and a good opportunity.”― Paul Lockhart
Teachers as Problem-Posers
Problem-Solving Resources
How are problem solving resources sourced for your
school?
Benefits to Teachers
Improve content knowledge
Improve ability
Improve confidence
Improve problem-posing capacity & self-efficacy
Benefits to Teachers
Improves beliefs and attitudes toward
mathematics
Professional Development for Teachers
Allows teachers to see the benefits of problem posing, & encourages implementation with students
Allows teachers to build their own resources for problem-solving sessions
Improves content knowledge, and problem-posing capacity
Increases confidence & improves attitude toward mathematics
Promotes rich mathematical discussion
Teacher Professional Development1. Identify a content area2. Choose a context3. Teachers generate as many
mathematical problems as they can4. Discuss
1. Multiplicative Thinking2. Out to dinner3. Teachers generate as many
mathematical problems as they can
4. Discuss
For Example...
Example Response...I went to dinner with two friends, Tim and Hala, and we shared
some dumplings. For every dumpling I ate, Tim ate 2, and Hala ate 3.
How many dumplings did my friends each eat by the time I’d had 4?
How many each would Hala & I have eaten if Tim had eaten 14 dumplings?
How many each would Tim & I have eaten if Hala had eaten 18?
How would we have shared a plate of 12 dumplings?

relevance etc.
1. Choose a concept that you think would benefit the teachers at your school
2. Pose as many mathematical problems as you can about a context that would be engaging for your colleagues

Collegiate Planning for Problem Solving
1. Problem-pose for students2. Open/context/content
3. Discuss the problem & anticipated responses
What questions will you ask the students who need scaffolding?
What questions will you ask the students who need extending?
What responses do you anticipate, and how will you address/assess them?

Students as Problem-Posers
Hi!
Benefits to Students
Encourages creative, flexible & reflective thinking
A deeper understanding
of the concepts and structures of
problems
Benefits to Students
Increases engagement and
enjoyment.Improves
attitudes and opinions
Demonstrate understanding
Highlight misconceptions
Benefits to Students
Play
Messy
Fun
Authentic, rich assessment of
content, thinking,
reflection, communication
& strategy
Students as Problem-Posers
Many benefits
Small scale: based on a book, toy, game or school location
Large scale: real-world, authentic problems
Solving their own or their peers’ problems is more engaging

“It is clear that the chief end of mathematical study must be to make
the students think.” – John Wesley Young
1. Identify content area, and/or2. Choose a context3. Students pose problems4. Discuss
1. 2-digit numbers2. An excursion to the zoo3. Student pose problems4. Class discussion
For Example...
Example Responses (anticipated)...We visited the elephants, then the zebras and the giraffes.
Which animal did we visit first?
There were 12 penguins, 18 meerkats, 23 birds, and 15 lemurs. Which animal were there most of? Put the animals in order
from least to most.
At the zoo, we saw 10 penguins and 3 monkeys. How many animals did we see altogether?
We saw 35 animals at the zoo.
We saw 36 animals’ legs at the zoo. Which animals and how many of them might we have seen?
Student Group Discussion
ProblemHas a problem been
posed?
StructureIs the problem open-ended?

1. Imagine your students are going on an excursion to the zoo. You invite your students to pose problems during the excursion.
2. Anticipate as many problems as you can that your students might pose

For Example...
Have a go!
1. Choose a difficult content area OR a student who is difficult to engage in mathematics
2. Think of a context to make the content more engaging to your student/s
3. Anticipate problems your student or students may pose

mathematics along the way – even if you don’t solve it at the end of the day.”
