Curated OER
Complex Analysis: Graphical Representations
In this graphical representation worksheet, students draw an Argand diagram depicting complex numbers. They draw in vectors that represent complex numbers. This three-page worksheet contains approximately ten problems.
Curated OER
Using Inequalities to Problem Solve
Students explore inequalities. For this Algebra I lesson, students solve and graph linear inequalities involving addition, subtraction, multiplication, or division. Students use inequalities to solve and graph real-world problems.
Curated OER
Solving Inequalities By Using Addition And Subtraction
Seventh graders solve inequalities using addition and subtraction. They write number sentences based on word problems.
Curated OER
The Power of Algebra
First graders explore patterns. They look for patterns in number problems and use algebra as a means of solving general problems. Students devise a strategy to solve the number problem.
Curated OER
Currency and Exchanges Rates
Seventh graders examine currency rates. In this exchange rate lesson, 7th graders visit selected websites to determine the exchange rates between specified currencies.
