# Activities to Teach Students About Perimeter And Area: Changes in Scale

When it comes to teaching math, it is important to engage students in activities that help them learn concepts. One such concept is perimeter and area, which are important mathematical concepts that students need to master. One effective way to teach students about perimeter and area is through activities that focus on changes in scale.

In this article, we will explore some activities that can help students understand changes in scale and how they impact the perimeter and area of shapes.

Activity 1: Scaling Shapes

The first activity that teachers can use to teach students about changes in scale is scaling shapes. In this activity, students will be given a shape, and they will need to scale it up or down to create a new shape.

The teacher can provide students with a grid and a shape, such as a rectangle or a square. Students can then use the grid to scale the shape up or down by a certain factor. For example, they can double the size of the shape, or they can halve it.

Once students have created the new shape, they can calculate the perimeter and area of both the original shape and the new shape. This will help students understand how changes in scale impact the perimeter and area of a shape.

Activity 2: Creating a Garden

Another activity that can help students understand changes in scale is creating a garden. In this activity, students will create a garden using different shapes and sizes of plants.

The teacher can provide students with a plan of a garden and a set of shapes and sizes of plants. Students can then use these plants to create a garden on the plan.

Once the garden is complete, students can calculate the perimeter and area of the garden. They can then scale the garden up or down by a certain factor and calculate the new perimeter and area.

This activity will help students understand how changes in scale impact the perimeter and area of a real-life object.

Activity 3: Measuring the Playground

The final activity that can help students understand changes in scale is measuring the playground. In this activity, students will measure the perimeter and area of the playground and then scale it up or down to create a new design.

The teacher can provide students with a map of the playground and a set of measurements. Students can then measure the perimeter and area of the playground.

Once the measurements are complete, students can scale up or down the playground to create a new design. They can then calculate the new perimeter and area of the playground.

This activity will help students understand how changes in scale impact the perimeter and area of a real-life object in a practical manner.

Conclusion

Teaching students about perimeter and area is essential in building a strong foundation in math. These activities that focus on changes in scale can greatly enhance students’ understanding of these concepts. By engaging students in activities that are hands-on and practical, teachers can create an interactive and engaging learning experience for their students.
