2. What is Cabri 3D?
Cabri 3D is a simple and comprehensive software to help students understand 3D geometry.
Students can actually open up 3D shapes
Modern & exciting alternative to physical geometry manipulative
Cabri 3D software helps bring concepts to life

3. The Basics Basic construction with planes, spheres, and lines
Construction of solids: pyramids, cylinders, etc.
Nets: unfolding polyhedrons into nets
Measurements & Calculations: what we are already familiar with plus 3D calculations (volume)

4. Advances in Cabri 3D
View from any angle: able to rotate objects a full 360 degrees
Animation tools: replay of steps
Intersections: discover the shape of intersections between shapes and planes

5. How can Teachers Utilize Cabri 3D?
Free 30 day trial at cabri.com
Even if students do not have individual computers, you can project your screen so the class can see
Helps students visualize different geometric concepts linked directly to NCTM standards (prove theorems, discover formulas, etc.)
Connections to physics, geometry, and the arts

6. Group Discover Create a cube and its net
Discover the intersection between a cube and a plane
Construct a dodecahedron

7. Our Lesson in Cabri 3D Inquiry-based lesson consisting of 3 activities
Nets
Discovering Surface Area
Box Length Problem

8. ½ * Perimeter * Slant Height + Base Area
Discover Surface Area
Regular Pyramid
= 4 * (1/2 B * H) + S² = ½ *(4*B)*H + S² =
½ * Perimeter * Slant Height + Base Area

9. Perimeter * Height + 2 * Base Area
Discover Surface Area
Regular Prism
= 5 * (S * H) + 2 B = 5S * H + 2B =
Perimeter * Height + 2 * Base Area
