3 Dimensional Shapes
Sign in to play this song with your class.
Sign inDEFINITION:
three dimensional shapes can be measured in 3 directions. A cylinder can be measured in height, width, and depth. Remember: Three dimensional shapes can be measured in height, width, and depth.
HOW TO:
Examples are spheres, cylinders,cubes and cones.
Everyday Use:
3 Dimensional shapes are used every day in drawing and in illustrations in books.
Lyrics
Okay class, so last time we learned about
2 dimensional shapes which are flat
Today we are going to talk about
3 dimensional shapes and what they look like
A sphere is like a circle
Except a circle is flat and a sphere is not
An example of a sphere is a basketball
A golf ball, or maybe even a tennis ball
A cube is like a square except a square is flat
And a cube is not
Some examples of a cube may be an ice cube
Or a box, a pyramid is like a triangle
Except, you got it a triangle is flat
Some examples of a pyramid may be
Those cool looking Egyptian pyramids
Or the top of a circus tent
Standards
- CCSS.MATH.CONTENT.K.G.B.4 — Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).
- CCSS.MATH.CONTENT.K.G.A.3 — Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").
- CCSS.MATH.CONTENT.HSG.GMD.B.4 — Identify the shapes of two-dimensional cross-sections of three-dimensional objects, and identify three-dimensional objects generated by rotations of two-dimensional objects.
