Exploring Negative Numbers: A Math Adventure

Learning Objective

Understand the concept of negative numbers and their application in real-life situations.

What do you already know about negative numbers?

What are Negative Numbers?

Negative numbers are numbers less than zero. They are denoted with a minus sign (-) in front of them.

Number Line

A number line can help us visualize negative numbers. It extends to the left of zero.

Subtracting Negative Numbers

Subtracting a negative number is like adding. The signs must be considered to find the difference.

Real-life Scenarios

Negative numbers can represent debts, temperatures below zero, loss of elevation, etc.

Challenge Task: Problem Solving

Solve word problems involving negative numbers to apply the concepts learned.

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.
