Family Math Activity: Make a Robot Piñata

Help your children explore 3D shapes while making a colorful piñata.
Support Provided By

Esta actividad también está disponible en español.

Young children use touch to explore and learn about shapes. In this hands-on arts activity, children will explore 3D shapes while making a colorful piñata. Fun fact: Piñatas originated in China, then were passed on to Italy and Spain by Marco Polo, and subsequently brought to Mexico. Today, piñatas can be found all over the world and they come in all shapes and colors.

Learning Goals

This activity will help your child:

  • Learn about shapes while enjoying the arts
  • Identify 3D shapes in everyday surroundings
  • Practice describing shapes by its number of sides (faces) and corners (vertices)
Robot piñata activity materials

Materials

  • Markers
  • Tape or glue
  • Pencil
  • Ruler
  • Scissors
  • Color construction paper
  • Colorful tissue paper/crepe paper
  • Cardboard tube (bathroom tissue roll)
  • Empty tea box

Step-by-Step Instructions

1. Create your robot's head: Trace each side of the tea box on the construction paper. There are six sides so you may want to use a variety of colors. Cut out the traced shapes and tape or glue them to the sides of the tea box.

2. Make your robot's body: Trace two circles on the construction paper using the end of the cardboard tube. Cut the circles out and tape or glue them to each end of the cardboard tube.

3. Make paper fringe (papel picado): An essential addition to your piñata is papel picado, the traditional fringe used in many modern piñatas. It is typically made using colorful tissue paper, but the fringe can also be achieved using crepe paper or construction paper.

4. Dress the body of your piñata: Dress the body by glueing the fringe to your base in rows, starting at the bottom so that the fringe above overlaps the previous row. Alternate colors to make an exciting pattern!

5. Make your robot a hat! To make a party hat for the robot, print the provided template. Cut out the shape provided and decorate while flat. Tape or glue the ends together using the provided guidelines to create a cone shape. Trace the open end of the cone on construction paper. Cut out and tape or glue this shape base of the cone.

6. Give your robot a face: Use markers to draw a face on one of the sides of the robot's head.

7. Assembly time: Assemble the robot by taping or glueing the bottom of the head to the top of the robot's body.

8. Decorate! Use markers and paper to decorate your robot. You can add arms and legs, control panels, tools — anything you can imagine!

Math Context for Activity

  • Have your child compare 2D and 3D shapes. How are they similar or different? Point out that 2D shapes are flat (lying in a plane) while 3D shapes are solid.
  • Explain solid shapes have vertices and faces. Vertices are just another way to say corners and faces or sides are flat surfaces.
  • Have your child hold each 3D shape and make observations about its attributes (e.g. name, color, number of sides, etc.) Which shapes roll? (A sphere). Which shapes have pointy corners (vertices)? (A cube or a cone).
  • Show your child the faces of the cube, cylinder, or cone. Point out that the flat faces of 3D shapes are actually 2D shapes! For example, a cylinder has two flat faces shaped like a circle.

Keep the Conversation Going

  • Practice drawing shapes and naming shapes.
  • Go on a “Shape Hunt” around the house or the neighborhood. Can you find something shaped like a sphere? What else do we have around our house that is round with no corners? (A ball, a globe).
  • Have your child combine shapes to make new shapes. For example, two right triangles can be combined to make a rectangle.
  • Construct a sphere!

Remembering Math and Civil Rights Activist Bob Moses

Omo Moses, now a math activist like his father, Bob Moses, remembers when he realized his father was more than just his dad. At school, he was told a great hero from the Civil Rights Movement was coming to visit. After seeing his dad, he "had a sense that who he was meant a lot to people — beyond just being my dad." After his death, we remember how the Harlem boy became a beloved activist, educator, visionary and leader.
