In Scratch code

• Explore the link between coding and growing patterns.
• Change the Scratch code to create your own.
• See details below for Scratch Version 1 - Bar Graph.

Math overview

See the interview with mathematician Lindi Wahl.

Code - play with the Scratch code

• The Counter starts at 1 and keeps increasing by 1.
• The number of squares = 3 * Counter.
• The number of diamonds = 2.
• Run the code to plot the bar graph.
• Change the values in the code and see how the bar graph changes.

Output

• Each bar is made of squares and diamonds.
• Change the numbers in the code to change:
  • the number of squares
  • the number of diamonds
  • the number of bars
• Which number(s) affect the steepness of the graph?
