CLARK, NJ - Carl H. Kumpf mathematics teacher Lauren Portas provided her seventh grade students with an interactive way to use proportions to scale objects. Students worked in groups to measure a doll of their choosing.
Using the measurements they collected and a scale that they determined, students wrote and solved proportions to calculate the measurements of each body part for their life-size drawing. The drawings were created using the new measurements to show how proportions can be used to scale an object larger.
“The students were able to see how the content that we are learning in class can apply to the real world. They loved seeing their dolls come to life.” stated Portas.
