CAPS #19 TODAY!!!!!!!

Marshmallow Lab In a group you are going to make 3-D figures that we just went over today in class. Marshmallows-Vertices Toothpicks-Edges After you complete a 3-D figure raise your hand and I will walk over to check.

What is a Net? Page 23

Nets Today’s Lesson: 1) We will learn how to represent three- dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. 2) We will learn how to apply these techniques in the context of solving real-world and mathematical problems.

Definition of a Net A net is a two-dimensional pattern of a three- dimensional figure, that can be folded to form the figure. nets

More about nets……. A net is the pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. A net is folded to make a three-dimensional figure. Some examples of nets

Review Prism vs. Pyramid PrismPyramid

What is a prism? The prism has two bases. The bases are joined together by the sides. The type of prism is determined by the shape of the base. For example: a triangular prism will have triangular bases, while a rectangular prism will have rectangular bases, an octagonal prism will have octagon bases, and so on.

What is a pyramid? A pyramid is a three-dimensional polyhedron. It has a base, which is a polygon. The base is connected to the sides or faces of the pyramid. The sides of the pyramid will always be triangular in shape. The sides of the pyramid meet the top. For example: a triangular pyramid will have a triangular base, while a square pyramid will have a square base, and so on.

Your turn to make a net….. 1) I will pass out a net to each person. 2) You will need to figure out what net I gave you in order to receive a pair of scissors 3) Cut out your net 4) Draw on your net what you are learning about in another class. Make it colorful. 5) Glue your net together
