Lesson 7: Sticker Art with Loops
Overview
Watch student faces light up as they make their own gorgeous designs using a small number of blocks and digital stickers! This lesson builds on the understanding of loops from previous lessons and gives students a chance to be truly creative. This activity is fantastic for producing artifacts for portfolios or parent/teacher conferences.
Purpose
This series highlights the power of loops with creative and personal designs.
Offered as a project-backed sequence, this progression will allow students to build on top of their own work and create amazing artifacts.

Objectives
Students will be able to:
- Identify the benefits of using a loop structure instead of manual repetition.
- Differentiate between commands that need to be repeated in loops and commands that should be used on their own.
Preparation
- Play through the lesson to find any potential problem areas for your class.
- Make sure every student has a journal.

Heads Up! Please make a copy of any documents you plan to share with students.
For the Students
- Think Spot Journal - Reflection Journal
Vocabulary
- Loop - The action of doing something over and over again.
- Repeat - To do something again.

Introduction
Students should have had plenty of introduction to loops at this point. Based on what you think your class could benefit from, we recommend:
- As a class, playing through a puzzle from the last lesson, "Loops with Rey and BB-8"
- Reviewing how to use Artist by playing through a puzzle from "Programming in Artist"
- Previewing a puzzle from this lesson
All of these options will either review loops or the artist, which will help prepare your class for fun with the online puzzles!
Main Activity (30 min)
Online Puzzes
Some students may discover where to add repeat loops by writing out the program without loops then circling sections of repetitions. If the students in your class seem like they could benefit from this, have them keep paper and pencils beside them at their machines. Students might also enjoy drawing some of the shapes and figures on paper before they program it online. (When drawing stamps, it can be easier to symbolize those with simple shapes like circles and squares.)

Journaling
Having students write about what they learned, why it’s useful, and how they feel about it can help solidify any knowledge they obtained today and build a review sheet for them to look to in the future.
Journal Prompts:
- What was today’s lesson about?
- How did you feel during today’s lesson?
- What was the coolest shape or figure you programmed today? Draw it out!
- What is another shape or figure you would like to program? Can you come up with the code to create it?
Student Instructions
"Go get the scrap metal, BB-8!"
Use five of the same blocks to get the scrap metal. Scrap metal glows like this: 
Student Instructions
What do you think will happen when you click "Run"?
BB-8 will not move.
BB-8 will move only one space
BB-8 will move 5 times and get all of the scrap metal
I don't know
Student Instructions
"Go BB-8!"
To get all the scrap metal, try creating a loop that uses only one block inside of a repeat block.
Student Instructions
"Keep it up, BB-8."
In this puzzle, two repeat loops will help you get BB-8 to all of the scrap metal with the fewest number of blocks!
Student Instructions
"Go BB-8!"
Student Instructions
"Can you get it all?"
Loops even work with more than one block inside! Can you loop this sequence?
Student Instructions
"You can do it!"
Can you try to get all the scrap metal using just one loop? Try programming it all out then finding the repeating code to put in a loop.
Student Instructions
"Keep it up, BB-8."
Challenge: Combine ideas from the last few puzzles to complete this level.
Student Instructions
"Keep going!"
Use what you have learned to pick up all of the scrap metal!
Student Instructions
"Go BB-8!"
You are doing great! Keep it up!
Student Instructions
Look closely at the code below. What will happen when you click "Run"?
BB-8 will travel too far in the first loop.
BB-8 will not travel far enough in the first loop in order to get all of the scrap metal.
BB-8 will collect all of the scrap metal with no problems.
I don't know.
Student Instructions
"Keep going, BB-8!"
You are almost there! This time, choose any path you like!
Student Instructions
Student Instructions
"Let's hunt for treasure!"
Help the collector get at least 5 pieces of treasure.
