Problem and Solution Archive from 2024/2025, 2023/2024
Visit the archive page to access links to booklets containing all the problems and solutions from the last two years. The problems are organized into themes, grouping problems into various areas of the curriculum.
Information for educators
Problems are organized into five themes: Algebra (A), Computational Thinking (C), Data Management (D), Geometry and Measurement (G), Number Sense (N). A problem may have more than one theme.
| Theme | Broad Topics |
| Algebra (A) | Patterning, Relations, Sequences, Functions |
| Computational Thinking (C) | Logic, Coding |
| Data Management (D) | Probability, Statistics, Counting |
| Geometry and Measurement (G) | Spatial Sense, Shape and Space, Trigonometry |
| Number Sense (N) | Numeration, Numbers, Number Theory, Financial Literacy |
These problems may be used in a variety of different ways including:
- posting the problems in a classroom,
- discussing the problems with students, and
- integrating the problems into their lessons.
We know that educators will use these problems in many creative ways!
Solutions will be sent out to educators one week after the problems are e-mailed.
