# Lesson 7: Loops in Artist

#### Loop | Artist

## 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.

## Agenda

### Warm Up (15 min)

### Main Activity (30 min)

### Wrap Up (15 min)

## 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 Course E Online Puzzles - Website corresponding to this course to find any potential problem areas for your class.
- Review CS Fundamentals Main Activity Tips - Lesson Recommendations.
- Make sure every student has a Think Spot Journal - Reflection Journal.

## Links

**Heads Up!**Please make a copy of any documents you plan to share with students.

## Warm Up (15 min)

### 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 stack design with loops just like in "My Loopy Robotic Friends"
- 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)

### Course E Online Puzzles - Website

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.)

## Wrap Up (15 min)

### 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?
