Drawing Views Lesson 4
Engage: Display a chart “Describing and Analyzing Structures” + tape one of the structure cards to it (or use card below) As students share their ideas, write them on the chart. Ask: What properties can be observed from looking at the picture? What ideas do you have about the shape?
Discuss: Compare student ideas with the following: “Describing and Analyzing Structures” The shape is made of cubes. It is a prism made of smaller prisms. There are nine cubes in the shape. There might be some cubes in the back that cannot be seen from the front.
Investigate: Putting together 3D shapes in different ways provides more info. about the shapes.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You will be working in pairs. Each pair needs 16 small cubes. Each pair needs to build the shape that they think is represented in the picture: How many cubes did you use to build this structure?
The top, side, and front views of a structure can be used to further analyze the structure. (As students share the following information, draw it on the grid space of white boardTE p. 37)- Have students duplicate the drawing on their white boards, too. In the structure build with 9 cubes stacked in an “L” shape: -How many square faces are visible from the top view? ____ -How many are visible from the front view? ____ -How many are visible from the side view? ____
Distribute the following to each pair of students: 1 folding magnetic whiteboard, 1 black marker with eraser, and 1 structure card. • Build the structure represented on your card. • Draw the top, side, and front views on the grid of the whiteboard. When both pairs in a group finish their structure cards: have the pairs switch cards and try to draw the views of this new structure; then compare and discuss both sets of drawings within the group.
Distribute the WS- “Record Sheet 4” (in a sheet protector) or students may draw the shapes on the whiteboards. Work with your partner to build the 2 structures. After the structures have been built, then represent the different views using the white board or the WS inside a sheet protector.
Reflect: Have each pair share with the group the different views that they came up with for both structures. Display chart “Describing and Analyzing Structures.” Review the ideas that were shared at the beginning of the lesson. Ask: Are there any additional ideas that can be added to the chart?
Chart on TE p. 40 Describing and Analyzing Structures • The only view that we can be sure of is the front view. It tells us there are six faces showing. • The side view lets us know there is an L-shape. We cannot tell if there is anything in back. • The top view shows us there are at least three faces. There could be more. • It might be a prism. • There might be more than nine cubes. • We cannot tell the surface area without seeing the views.
