How big is that?

8th Grade Math

Â» Unit:

Scale of the Universe: Fluency and Applications

Big Idea:The only way to work fluently with large numbers is by using your number sense and the laws of exponents.

Introduction to volume of 3D solids

8th Grade Math

Â» Unit:

VOLUME OF CYLINDERS, CONES, AND SPHERES

Solve problems involving volume

8th Grade Math

Â» Unit:

VOLUME OF CYLINDERS, CONES, AND SPHERES

Big Idea:How do I apply understanding of volume to complex, multi-step problems?

Day Four & Five

8th Grade Math

Â» Unit:

Welcome Back!

Cylinder Volumes (Part 1)

8th Grade Math

Â» Unit:

Volumes of Cylinders, Cones, and Spheres

Big Idea:Which cylinder is larger? Students make conjectures, then do the math.

Speaking of Spheres (Day 1)

8th Grade Math

Â» Unit:

Volumes of Cylinders, Cones, and Spheres

Big Idea:What's the relationship between the volume of a sphere and that of a cylinder of equal height and diameter?

Cylinder Volumes (Part 2)

8th Grade Math

Â» Unit:

Volumes of Cylinders, Cones, and Spheres

Big Idea:Students need to learn the basics underlying the volume formula, so they can apply it with meaning.

Volume Mastery Assessment (Day 2)

Quantum of Solids- Day 1

8th Grade Math

Â» Unit:

Quantum of Solids

Big Idea:Through hands-on exploration, students develop and test hypotheses about the volume relationships among these related solids.

Quantum of Solids- Day 2

8th Grade Math

Â» Unit:

Quantum of Solids

Big Idea:Using a foldable, students will organize their understanding of volume formulas and then practice applying them to three-dimensional solids.

Quantum of Solids- Day 4

8th Grade Math

Â» Unit:

Quantum of Solids

Big Idea:Now that students have had a few days of practice applying the volume formulas, it is time to give them a real-world problem to solve that will put these new skills to use.

Quantum of Solids- Day 3

8th Grade Math

Â» Unit:

Quantum of Solids

Big Idea:Estimating volumes is one of the most difficult of estimating tasks. Today, students must use their knowledge of the volume of cylinder formula to rank eight cylinders in descending order of volume.

Quantum of Solids- Days 5 - 7

8th Grade Math

Â» Unit:

Quantum of Solids

Big Idea:As a formative assessment for this unit, students will design and create a "Solids Pet" using cylinders, cones, spheres and other geometric solids. They will then calculate the volume of their pet and compare it to their estimation.

8.G.C.9
