[accordion-item title=”Reveal”]

Click “See Inside” the “Shapes Patterns” project to show students the 5 different variations.

Here is the code for this project. Which of these did you find? What new patterns did you create?

Consider sharing the following screenshots with students:

Image #1 is the full coding script that students would ideally have created.

Point out the triple nested loop for the square, where the square is one repeating pattern of lines, and the squares moving up, then down, are another pattern, both of which need to be repeated as a 3rd pattern.

Discuss how they can use the fact that a circle is 360 degrees to get their sprite to arrive back at the starting point of their pattern (e.g., if the sprite turns 36 degrees, and they repeat that 10 times, it is a full rotation, but they need to repeat 8 times if turning 45 degrees). ​

You can also bring out the connection of how an octagon has 8 sides, and its internal angles are 45 degrees.​

You can draw a connection between the factors of 360 and how that can help find how many times to repeat for a given degree of turn (The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360.)​

[accordion-item title=”Reflect”]

Provide students an opportunity to reflect on their learning by offering these consolidation prompts to be completed independently.

We suggest collecting this reflection as an additional opportunity to engage in the formative assessment process to inform next steps for individual students as well as how the whole class will proceed.
