Overview
This lecture focused on solving and interpreting inequality word problems, providing examples and practice opportunities.
Examples of Inequality Word Problems
- Inequality word problems involve translating real-life scenarios into mathematical inequalities.
- Example problems may include situations about money, age, or quantities where a limit or minimum/maximum is specified.
- Solving these problems requires identifying variables and constructing an inequality based on the situation.
- Key steps: define the variable, write the inequality, solve for the variable, and interpret the solution.
Practice and Student Engagement
- Students were prompted to try solving similar inequality word problems on their own.
- Opportunities were provided to check answers and reflect on performance.
Key Terms & Definitions
- Inequality β a mathematical statement showing that two expressions are not equal, using symbols like <, >, β€, or β₯.
- Variable β a symbol (often x or y) representing an unknown quantity in an equation or inequality.
Action Items / Next Steps
- Practice more inequality word problems from the textbook or online resources.
- Review notes on translating word problems into inequalities.
- Prepare questions for the next class on challenging problems.
