3-D Volume Model Wonder

My students need these seven 3-D figures kits to do a hands-on investigation to discover volume formulas and their relationships.

My Students

My students work in collaborative groups daily to discover mathematics in their everyday lives. We use manipulatives whenever possible to further our understanding of a problem.

My school is full of great students!

We are at about 60% free and reduced lunch, with around one third of our students identified as minority. I teach one high level class for high school credit and three normal eighth grade math classes. When my regular eighth grade math students come into my classroom, they often feel defeated that they did not place into the high level class. It is my challenge daily to engage them and show them that math is not only fun, but a necessity to their lives. Any time I can incorporate hands-on activities, my success rate in that challenge increases! I have hard-working students who love to engage in the math. I work closely with another math teacher in eighth grade. We are asking for seven Transparent Relational Geometric Solids kits. We will be able to share these 3-D figures between our two classes so the impact will be for all eighth graders at our school!

My Project

With the Transparent Relational Geometric Solids I will create hands-on investigations for my students that will allow them to discover the relationships between volume formulas and their area formulas. Students will discover how a cone is related to a cylinder, where the formula for a sphere comes from, why a pyramid requires you to divide by three . . . and so much more! Students will get to use water, food coloring, and these shapes to investigate volume formulas. They will also have these models when we begin solving problems with 3-D shapes. Having the visual model to touch and turn is vital to their understanding in so many problems. I am asking for seven sets because I have my students in groups of four for collaborative learning.

Do you remember the formula for the volume of a cone?

Do you know how it relates to the volume of a cylinder? Do you know from where the formula for a sphere derives? How many of you learned these formulas through memorization? Your teacher told you the formula, you wrote it several times, made flashcards, and then spit it out for a test. Do you remember them now? With your help I will create lessons for my students that give them an experience to remember!
