Chapter 11 Put on Those 3D Glasses!
3D is all of the rage so bring on some 3D shapes!!
Now we are going to explore a whole new world of math but looking at
shapes, solids, and fractions. In other words we will be talking about
Geometry!! There is a lot of new vocabulary in this chapter so take it
slow and everyone will get it. A lot of kids really like this chapter
because a lot of kids are builders at heart. They have been playing with
blocks and in sand boxes for years so building is really cool and is
something that the children are really comfortable with!!
***A KEY concept to this chapter is that there is a difference between
SHAPES and SOLIDS. Shapes are flat and solids are 3-D. We say in class
that solids you can touch all of the way around and shapes are flat as
we slap the desk. ***
VOCABULARY-
cone - a 3D figure with a round base and a point at the top
cube - a square 3D figure such as a box
curved suface - a rounded surface
cylinder - a 3D figure with flat circular ends and a curved surface such as a tube
faces/flat surface - the flat parts of a solid figure
rectangular prism - a rectangular 3D figure such as a brick
sphere - a round 3D figure such as a ball
vertices
- the points where the flat parts of the solids meet (in a flat shape
these are called corners). We say these are the “ouch” points of the
solid.
1. SOLID FIGURES-
Solid figures are all around us and now we get the chance to give these
solids a name. The solids that we will be talking about are the
following:
1. Cube
2. Rectangular Prism
3. Cone
4. Sphere
5. Cylinder
We talk about the properties of the solids. We notice which ones roll,
slide, and stack. This allows us to see that some solids have flat parts
called “faces”.
We also do what comes naturally with 3D shapes...we build with them and knock them down!
Activities for Chapter 11
1. 3D Recycling
Materials: anything that can be recycled for example, paper towel rolls, tissue boxes, oatmeal boxes
Procedure:
1. Have your child indentify a place they would like to go.
2. Look up that destination on the internet if possible or at the library to identify the key buildings or places.
3. Hunt through the house for solids that are made of recycled material such as paper towel rolls or shoe boxes.
4. Have the child decorate each item to show the important
buildings from the destination and then put together on a big poster
board and let the adventure begin!
2. 3D Godzilla Memory
Materials- blocks
Procedure:
1. Set up a tower made out of blocks and give the child 5 seconds to study the tower.
2. Yell “Godzilla” and knock it down.
3. Have the child rebuild the tower.
