Follow the instructions in the video below to draw a square. Make sure it is two blocks by two blocks.
Use the location graph in the sensor data to calculate the perimeter of this square. (Remember that perimeter is the sum of all sides).
What unit of measure does the location graph show?
Draw a representation of the same square on the handout. Be sure to label the sides of your square.
Use the location sensor data from the graph to measure each side of the square Remember that a square has four equal sides. Now calculate the perimeter of this square using the blank equation on the handout. How big is your square?
Properties of a Rectangle
Properties of a Rectangle
Start a new Draw program and name it "Rectangle."
A rectangle has four straight sides like a square, but can have one pair of opposite sides that are longer than the other pair.
Draw a rectangle and have your partner check your rectangle for accuracy. Make it three squares by five squares. Run the program so your Sphero makes a rectangle.
Watch the sensor data. How is it the same and different from the square?
Now, just like you did with the square, draw your rectangle on the handout. Use the location data to help you calculate the perimeter of your rectangle. Show your work on the handout.
Properties of a Triangle
Properties of a Triangle
Start a new Draw program and name it "Triangle."
A triangle has 3 straight sides and 3 points (or vertices).
Draw a triangle and be sure to have your partner check your triangle for accuracy. Run the program so your Sphero makes a triangle.
Watch the sensor data. How is it the same and different from the square and rectangle?
Now, just like you did with the square and rectangle, draw your triangle on the handout. Use the location data to help you approximate the perimeter of your rectangle. Show your work on the handout.

Draw a shape with 6 sides in the draw canvas and calculate the perimeter of the shape Sphero makes.
What is the name of a shape with six sides?
