The class was not sure they had heard Miss Lopez correctly. Did she really say they would build robots? They hoped so. Building robots would be fun!66page0006page0006.xhtmlWe are building robots today! 77page0007page0007.xhtmlShaping Up The class had studied three-dimensional (3-D) shapes all week long. They learned about cones and cubes. They learned about other shapes, too. Each is a 3-D shape. cube rectangular prism triangular prism88page0008page0008.xhtmlcone cylinder sphere Let's Do Math! Miss Lopez plays a game with students. She gives them clues about 3-D shapes. Help students name the shapes. 1. I am a solid shape. I am round like a ball. What am I? 2. I am a solid shape. I have 6 faces that are squares. What am I?99page0009page0009.xhtml1010page0010page0010.xhtmlMiss Lopez said the class would build robots from 3-D shapes. Students would work in teams to build the robots. Each team would build its own robot.1111page0011page0011.xhtmlGetting Started Teams had to think about where to use each shape. One team started with a rectangular prism. It would be a power pack. It would make the robot move!1212page0012page0012.xhtmlThe power pack is a rectangular prism.1313page0013page0013.xhtmlThe can for the robot's body is a cylinder.1414page0014page0014.xhtmlThat team also found a good use for the cylinder. It would be the robot's body. They strapped it to the power pack. Then, they added the arms. Their robot was coming to life!1515page0015page0015.xhtmlAlmost Finished The team looked at all the pieces. They tried to see which 3-D shapes were left. They made funny eyes out of spheres!1616page0016page0016.xhtmlThe eyes are two spheres. Let's Do Math! Another group wants its robot to hold an ice cream cone like this one. Choose the shapes they need. A. cone B cube C sphere D prism1717page0017page0017.xhtmlLast, the team wanted to find a hat for its robot. They took a cone and placed it on top. The robot was complete! The top of the robot's hat is a cone.1818page0018page0018.xhtmlLet's Do Math! Miss Lopez loves the robot hat! She builds a head and a hat like this one for her robot. 1. What two shapes does Miss Lopez use to build her robot head and hat? 2. What 3-D shapes would you choose to build a robot head and hat? Why?1919page0019page0019.xhtmlProud Teacher Miss Lopez was proud of all the teams. They had learned a lot about 3-D shapes. They had fun, too.2020page0020page0020.xhtmlThe class could not wait to get started on their next 3-D project! The 3-D robot is ready to go!2121page0021page0021.xhtmlProblem Solving Help one of Miss Lopez's robot teams design a robot. Build or draw a robot using cubes, spheres, cylinders, rectangular prisms, and cones. Complete the sentence frames to describe your robot. Then, answer the question. 1 My robot's name is _______. Its head is a _______. Its eyes are _______. Its body is a _______. Its arms are _______. Its legs are _______. 2 Compare your robot to the one on page 21. How are they alike? How are they different?2222page0022page0022.xhtml3-D Robot Builder2323page0023page0023.xhtmlGlossary cones solid shapes with flat, circular bases and one curved surface cubes solid shapes with six square faces cylinder solid shape with two circular bases and one curved surface faces flat surfaces of 3-D shapes rectangular prism solid shape with rectangular faces spheres solid round shapes2424page0024page0024.xhtmlIndex 3-D shapes cones cubes cylinder rectangular prisms sphere triangular prism2525page0025page0025.xhtmlAnswer Key Let's Do Math! page 7 : 1 sphere 2 cube page 15 : A, C page 17 : 1 cylinder, rectangular prism 2 Answers will vary.
