Lesson Plan - Get It!
Have you ever seen a 3D movie? If you have, you know things look like they are coming out of the screen where you can almost touch them! If you haven’t seen a 3D movie, close your eyes and imagine Spiderman swinging from building to building. Now, imagine Spiderman coming out of the screen and swinging right past you to the next building! Seeing Spiderman on the screen, then seeing Spiderman come at you, is the difference between 2D and 3D!
Do you know what the "D" stands for in 2D and 3D?
It stands for the word, "dimension." I bet you will impress your parents if you tell them that! This quick video, Dimensions, from Mathematics is Fun, will help you understand a bit more about dimensions and the solid shapes you will learn about in this lesson:
Imagine a block. What shape is it? How about an ice cream cone; what shape is that? A baseball, what shape is that? If you said a square, a triangle, and a circle, you are right! That is, you were right if you were going to draw them on paper, which is 2D. What if you were holding the objects in your hand? Would the objects still be named square, triangle, and circle? Watch 3D Shapes I Know (solid shapes song- including sphere, cylinder, cube, cone, and pyramid) from Harry Kindergarten Music to find out:
What did you find out? What is the name of a block shape?
Yes, a cube! What about the shape of a ice cream cone? Yes, a cone! What about a baseball shape? Correct, a sphere!
Now, you are ready to move on to the Got It? section to show what you know!
