I wrote this circuit as a request for a middle school 8th grade math teacher, however, a high school geometry student or even a student preparing for a standardized test would get a lot of use out of this set of 16 exercises too. The volumes included are rectangular prism, cylinder, cone, sphere, hemisphere, and a few composite solids. Most of the questions are word problems where the students have to sketch and label the appropriate figure before making the calculation. Several are "find the missing dimension given the volume and another dimension."
All answers are rounded to the nearest whole number and students should use their pi button for calculations. The formulas are not on the circuit so the teacher can decide whether students may use a formula sheet or not.
A note about circuits: Students advance in the circuit by searching for their answers. This format keeps my students engaged! Productive! Talking about math! They don't get up when the bell rings!
I do not include an answer key because the answers are embedded in the circuit. The teacher needs to work the circuit first to determine how best to use the resource with his or her students. My colleagues and I check our circuits very carefully but if you feel like there is a mistake or if you get stuck, please do not hesitate to contact me! firstname.lastname@example.org
