What is an ALGORITHM?
A list of steps that you can follow to finish a task
In mathematics and computer science, an algorithm is a self-contained step-by-step set of operations to be performed.[1]

What is a TANGRAM?
The tangram is a dissection puzzle consisting of seven flat shapes, called tans, which are put together to form shapes.[2]

You are going to use your Tangrams in a slightly different way than most. Instead of looking at your puzzles and trying to guess which shape goes where, you are going to get puzzles that already tell you where each shape goes.

You might think that this will make it easier, but it won't, because you will not get to actually look at the image that you are trying to recreate! Instead, one of your teammates will be describing the image to you.
To keep it from getting too difficult, at first, we will not use puzzles that require all seven pieces.

  1. Divide into groups of 3-5.
  2. Each player should cut out their own set of tangrams and an envelope to put them in.
  3. Have one member of each group select an Algorithm Card without showing it to anyone else.
  4. The person with the Algorithm Card will try to explain the image to everyone else without letting them actually see it.
  5. The other players will build their pictures off of the description given by the Card Holder.
  6. When the Card Holder is done, everyone will show their pictures and see if they all ended up with the same image.
  7. If everyone ends up with the same drawing, the Card Holder can show the card and see if everyone matched the card.
  8. If any of the pictures in the group are different from each other, have the Card Holder try describing the image again, using more detail.
  9. Choose a new Card Holder and a new Algorithm Card and repeat until everyone has had a chance to describe an image.
  10. When each team member has had a turn, try one of the extension activities below. You may want to try shapes that use all 7 tans; come up with shapes that use TWO sets of Tangrams; what about a game of TANGRAM DOMINOES; or trying to make TANGRAM WALLPAPER with all of you sets! IF you create one that you want to share, you may glue the Tangrams to a sheet of paper.
