Chapter 11: 3-D Geometry

Designing a Playground

INTRODUCTION

2-D and 3-D shapes are everywhere! You see them at school and at home, in the country and in the city, outside and inside. Once place where shapes are not only seen but also used is in a playground. Do you ever wonder who designs playgrounds? Whoever the designers are, they need to know a lot about shapes to make a great playground!

 

THE TASK

Ms. McPlayalot, the principal of your school, wants to design and build a new playground for your school, but she needs help! She has asked all the students in your class to get together in groups of two and design the best playground they can. The only rule is you must include as many 2-D and 3-D shapes as possible because more shapes make a better playground. You should be as imaginative as possible, just be sure to use lots of 2-D and 3-D shapes!

You must draw your design and then build a model of your design. The models can be photographed, and you will write a detailed description of your playground to accompany the photo of your model.

 

THE PROCESS

  1. The first step is to draft your playground, which means making a detailed drawing or ‘plan’ of your playground. Your drawing should look like a diagram that you can follow when you build your model. Using a large, blank sheet of paper, draw your design in pencil. Remember to include as many 2-D and 3-D shapes possible. Visit the following websites to get ideas about playground designs and different pieces you may want to include.

    Little Tikes

  2. Look at the different 2-D and 3-D shapes that you and your partner have included in your playground. Make sure you can both name and describe all of the different shapes.

  3. Construct a 3-D model of you and your partner’s playground design. You can use all sorts of different materials to create your model, including:

    Pipe cleaners
    Popsicle sticks
    Straws
    Glue
    Toilet rolls
    Cardboard/construction paper
    Empty boxes
    Modelling clay

    You can also ask your teacher for nets of 3-D shapes that you can fold, tape, and use in your model. Go to Nets for 3-D Shapes to get printable versions of various nets.

  4. Write a description of your playground. Write about each piece that you made, identify all the shapes it uses, and explain the purpose of the piece, or why it’s fun!

ASSESSMENT

  Level 1 Level 2 Level 3 Level 4
Problem-Solving and Application of Procedures (design  and model of playground) The student did not choose an appropriate variety of shapes and/or the shapes for the playground are very simple. Many of the shapes in the student's model do not match the shapes in their drawing. The student chose an appropriate variety of shapes for the playground with assistance. Several of the shapes in the student's model do not match the shapes in their drawing. The student chose an appropriate variety of shapes for the playground. The shapes in the student's model match the shapes in their drawing. The student chose a wide variety of appropriate and complex shapes for the playground. The shapes in the student's model directly match the shapes in their drawing.
Communcation (playground description) The student's description is incomplete or inaccurate. The student made major error/ommissions when identifying the shapes used. The student's description is mostly accurate. The student made a couple of errors/omissions when identifying the shapes used. The student's description is complete and accurate.
