Interactive Activity: Identify the Variable

Given the equation '2x + 5 = 15', identify the variable in the equation.

Interactive Activity: Find Examples

Find three examples of variables in real-life situations and share them with the class.

Recap and Summary

In this lesson, we learned that variables are symbols or letters that represent changing values. We explored examples of variables, similar words, and opposite words. Keep practicing and applying your knowledge to enhance your understanding.

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.
