Math Activities for 14 Year Olds

Fun, hands-on activities to practice math at home

1

Systems of Equations Real-World Problems

Create and solve real problems using systems of equations: comparing phone plans, break-even points for businesses, mixture problems. Graph and solve algebraically to check.

Materials: Graph paper, Calculator, Real-world scenario cards, Solution verification sheet
2

Function Exploration

Explore different representations of functions: tables, graphs, equations, verbal descriptions. For a given situation, create all four representations and explain connections.

Materials: Graphing calculator or Desmos, Function representation template, Real-world contexts
3

Polynomial Operations Challenge

Practice polynomial operations through puzzles and games. Create polynomial expressions that result in specific answers. Work backward from products to factors.

Materials: Polynomial puzzle cards, Algebra tiles (physical or virtual), Solution key
4

Linear vs. Exponential Growth Investigation

Investigate situations that show linear growth vs. exponential growth. Create tables, graphs, and equations for each type. Analyze why exponential growth is more dramatic over time.

Materials: Spreadsheet software, Graphing tools, Growth scenario cards, Comparison chart
