Introduction
This Grade 6 Mathematics lesson plan on “Absolute Value” helps teachers teach students to determine the distance of a number from zero, understand absolute value, and apply it in problem solving.
Main material
Lesson objective: to develop understanding of absolute value and teach students to use it for comparison and calculations.
Expected outcomes:
students understand that absolute value is the distance from zero;
calculate absolute values of positive and negative numbers;
use absolute values to compare numbers and solve problems;
apply knowledge in practical situations.
Lesson structure:
Organization
Greeting.
Prior knowledge

New topic
Absolute value is the distance from zero
Notation: |a|
Examples: |5| = 5, |-3| = 3, |0| = 0
Comparing numbers using absolute value: |−4| > |2|
Practice
Compute absolute values: -7, 8, 0, -2
Compare by absolute value: 5 and -6, -3 and 2
Practical problem: temperature at night -6°C, daytime +4°C. Find the absolute change
Consolidation
Pair work: discuss solutions, check accuracy, explain steps.
Reflection
Discuss applications (distance, temperature, finance).
Conclusion
Summary, brief feedback, mention results (5–10%).
Teaching methods: explanation, practical work, pair work, visualization, discussion.
