Math in 9th Grade: Functions and Systems of Equations in Everyday Life
During this semester’s three-week math block, 9th-grade pupils have been diving deep into functions and systems of equations.
As part of their learning, they created their own math books—a method to explain concepts in their own words, illustrate them with graphs, and reinforce their understanding with practice exercises.
🔍 Practical Example: Comparing Phone Plans
To show the real-world value of functions and systems of equations, the pupils worked on various tasks, such as comparing phone plans with different base fees and per-minute charges. They solved these systems both algebraically and graphically in a coordinate system.
The Self-Made Math Book:
- Theory in their own words: Each pupil wrote personal explanations of functions and systems of equations.
- Drawings and graphs: Every topic is illustrated with hand-drawn diagrams.
- Practice exercises: The pupils actively applied what they learned.
Handmade and full of ideas: 9th grade creates their own math book
