Recognise Negative Numbers In Practical Contexts (E.G. Temperatures) Lesson Plan for 7th Grade Students

Topic: Negative numbers in practical contexts (e.g. temperatures)

Objectives & Outcomes

By the end of this lesson, students will be able to:

Recognise negative numbers in practical contexts (e.g. temperatures)

Materials

Thermometer

Water

Drops of food coloring

White paper

Pencils

Warm-up

Ask students to provide examples of numbers that they are familiar with.

Ask for examples of numbers that are less than 0.

Ask for examples of numbers that are greater than 0.

Presentation

Hold up a thermometer and ask students to estimate the temperature based on the number on the thermometer.

Have a few students volunteer their estimates and see if they are correct.

Ask students how they determined the temperature based on the number on the thermometer.

Explain that negative numbers indicate a temperature below 0 on a thermometer.

Have students work in pairs to create a table of negative temperatures and corresponding numbers.

Have students work in pairs to create a graph of negative temperatures and corresponding numbers.

Guided Practice

Have students work in pairs to create a table of negative temperatures and corresponding numbers.

Have students work in pairs to create a graph of negative temperatures and corresponding numbers.

Ask students to share their work with the class and discuss any questions or challenges they had.

Independent Practice

Have students create their own table or graph showing negative temperatures and the corresponding numbers.

Encourage students to use their own examples or data to create their tables and graphs.

Closure

Ask students to share their tables and graphs with the class.

Discuss any patterns or observations that students have made about negative temperatures and negative numbers.

Ask students to share their examples or data that they used to create their tables and graphs.

Assess:

Observe students during the independent practice to ensure that they are using appropriate methods to represent their data, recording their results accurately, and recognising negative temperatures and negative numbers in their examples or data.

Collect and review students' tables and graphs to assess their understanding of negative temperatures and negative numbers.
