how to make math machine working model

Creating a math machine working model using cardboard is a creative and engaging way to demonstrate mathematical concepts. Let’s design a simple math machine that can perform addition and subtraction operations.

Materials Needed:

  1. Large piece of cardboard
  2. Colored markers
  3. Scissors
  4. Craft knife (with adult supervision)
  5. Popsicle sticks or dowels
  6. Small cardboard boxes or containers
  7. Glue
  8. Ruler
  9. Velcro dots (optional)

Steps to Create the Math Machine:

Step 1: Base Construction

  1. Cut the cardboard into a rectangular base for your math machine.
  2. Draw a clear grid on the base to represent the input and output areas.

Step 2: Input and Output Sections

  1. Designate one side of the base as the input section and the other side as the output section.
  2. Use markers to label each section.

Step 3: Operation Components

  1. Cut small cardboard boxes or containers to represent operation components. These will be attached to the input section.
  2. Label each container with a mathematical operation symbol (e.g., +, -).

Step 4: Operation Symbols

  1. Cut out operation symbols from colored paper or cardboard.
  2. Attach these symbols to Popsicle sticks or dowels, creating a set of movable operation symbols.

Step 5: Attaching Operation Symbols

  1. Glue the Popsicle sticks or dowels with the operation symbols onto the containers in the input section.
  2. Ensure the symbols are securely attached but can still be moved.

Step 6: Input Numbers

  1. Cut out numbers from colored paper or cardboard.
  2. Attach these numbers to Popsicle sticks or dowels to represent input numbers.

Step 7: Attaching Input Numbers

  1. Glue the Popsicle sticks or dowels with input numbers onto the input section of the base.
  2. Ensure the numbers are securely attached but can be moved.

Step 8: Output Section

  1. Cut out a rectangular slot in the output section of the base.
  2. This slot will be used to display the result of the mathematical operation.

Step 9: Testing the Math Machine

  1. Move the operation symbols and input numbers to perform addition and subtraction.
  2. Display the result in the output section.
