Same & Different: What’s in My Robot?

Look at the two pictures. What do you notice?

A. shows a chart of the shapes in Dustin's robot. Dustin used tally marks to record how many of each shape. Cylinders: 6. Cone: 1. Rectangular prisms: 5. B. shows a chart of the shapes in Raven's robot. Rave used numerals to record how many of each shape. Cylinders: 4. Cone: 1. Rectangular prisms: 7.
  1. How are pictures A and B mathematically the same, and how are they different?
    • A and B are the same because …
    • A and B are different because …
  2. What shapes would you use to build a robot? Choose some of the shapes below.
Choose from these shapes. 8 rectangular prisms, 8 cylinders, 8 cones, and 8 cubes.

Then make a third picture that shows how many of each shape are in your robot.
Explain how your picture is the same as pictures A and B, and how it is different.

You can use the outline below to start a graph or table.
If you have another idea for your picture, draw your own!

A blank chart with two columns. One column is for recording shapes. The other is for recording how many of each shape.
