Lesson 9: 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.

  • 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:

  • Creating a new dance with loops just like in "Getting Loopy"
  • 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)

Teaching Tip

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.)

Course C Online Puzzles 2018 - Website

This lesson may feel very different from what has come earlier in the course. After solving three puzzles, the lesson shifts to a project that student will build gradually in steps. These levels have some new characteristics you may want to explore before starting.

  • Levels 4-12 are the "free play" type which means they are not checked for correctness. Empower your students to determine when they have completed each task.

  • Levels 4-11 are linked. The code your students write in one level will automatically transfer over to the others. This allows them to build gradually and iterate on their ideas as they learn. Level 12 allows students to build something entirely new from scratch!

  • Encourage creativity! The instructions give examples but it is okay for students to experiment with different stickers or types of designs. The solutions we provide are not the only solutions!

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?
