Exploring Algebraic Expressions

Exploring Algebraic Expressions

Learning Objective

At the end of the lesson you will be able to understand and solve basic algebraic expressions.

What do you already know about algebraic expressions?

What is Algebra?

Algebra is a branch of mathematics that involves symbols and letters representing numbers in equations and formulas.

Variables and Constants

Variables are symbols that represent unknown or changing values, while constants are fixed values.

Algebraic Expressions

Algebraic expressions are mathematical phrases that include variables, constants, and operations like addition, subtraction, multiplication, and division.

Solving Equations

Equations are algebraic expressions with an equal sign, and solving them involves finding the value of the variable that makes the equation true.

Practice Time

Solving exercises and problems involving algebraic expressions and equations.

Word Problems

Applying algebraic expressions to real-world scenarios by translating word problems into equations and solving for the unknowns.

Wrap-Up and Review

Summarize key concepts and encourage students to ask any remaining questions.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
