# Activities to Teach Students About Perimeter, Area, and Volume: Changes in Scale

In mathematics, the study of perimeter, area, and volume is crucial in understanding the spatial relationships between shapes and objects. Teaching students about these concepts can be challenging, but using activities that incorporate changes in scale can make the lessons more engaging and dynamic.

Here are some activities that teachers can use to teach students about perimeter, area, and volume while also introducing changes in scale:

1. Build a City:

Have students design a model city using various shapes and sizes of buildings. They can calculate the perimeter and area of each building and determine the total area and perimeter of the entire city. You can also introduce changes in scale by having students design a miniature version of the city and calculating the area and perimeter of the smaller model.

2. Sugar Cube Skyscrapers:

Provide students with sugar cubes and glue, and have them build miniature skyscrapers. Students can calculate the volume of each building and determine the total volume of the city. To introduce changes in scale, have students build a larger version of the skyscrapers using larger building materials and then compare the volumes to the miniature versions.

3. Geometric Art:

Allow students to make art using geometric shapes such as squares, triangles, and circles. Have them measure the perimeter and area of each shape and the total perimeter and area of their artwork. To introduce a change in scale, have students create a larger version of their artwork and compare the measurements to the smaller version.

4. Pizza Party:

Bring in pizza to the classroom and have students calculate the area and perimeter of each slice. They can also determine the total area and perimeter of the entire pizza. To introduce a change in scale, have students make a larger pizza and compare the measurements to the smaller pizza.

5. Lego Creations:

Provide students with Lego blocks and have them build structures. They can calculate the volume of each structure and determine the total volume of their creations. To introduce changes in scale, have students build a miniature version of their structures and compare the volumes to the larger version.

In conclusion, incorporating changes in scale into activities that teach students about perimeter, area, and volume can be an effective way to engage and educate them. By exploring these concepts through hands-on activities, students can deepen their understanding and become more confident in their math skills.
