Tangrams Worksheet - Computational Thinking
1. NAV BAR
A tangram is a puzzle that uses small, often brightly colored, wooden blocks to form different shapes. Here we will use coordinates to draw those small block shapes and create a picture.
This worksheet may be completed individually or in pairs and is suitable for ages 9 and up.
Draw, individually or in pairs, basic shapes by connecting points described by coordinates.
A tangram is a Japanese game that uses regular shapes, like squares and triangles, to make larger shapes.
We can make those squares and triangles by marking down coordinates and connecting them together.
That is how computers can draw shapes, by using coordinates to draw lines on your screen.
Coordinates are pairs of numbers, like (5, 1). They help you find places on a grid.
The first number tells you the horizontal position of a point, it tells to you go across the x axis until you hit the number 5.
The second number tells you the vertical position of a point, it tells to you go down the y axis until you hit the number 1. (across, down)
In the image you can see the position of the coordinates (1, 1), (5, 1), (5, 5) that have been joined together to form a triangle.
These puzzles are available in a print version or online.
Requirements: Worksheet, pencil and ruler or a computer with Internet access
Optional: Colored pencils
This can be an individual or pair exercise.
Place and connect the coordinates on the grid to make a shape:
Click each coordinate on the grid to make a shape:
To draw shape 1 in the first grid. (5, 2), (9, 6), (5, 10), and (1, 6):
Easy: Let players refer to the answer sheet and see the shapes.
Medium: Tell players the rough shapes they are drawing, or let them see the answers before drawing.
Hard: Give no hint to the answer as players work through the instructions
