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.

In this online activity, students will have the opportunity to push their understanding of loops to a whole new level. Playing with the Bee and Plants vs Zombies, students will learn how to program a loop to be inside of another loop. They will also be encouraged to figure out how little changes in either loop will affect their program when they click `Run`.

Variables are used as placeholders for values such as numbers or words. Variables allow for a lot of freedom in programming. Instead of having to type out a phrase many times or remember an obscure number, computer scientists can use variables to reference them. This lesson helps to explain what variables are and how we can use them in many different ways. The idea of variables isn't an easy concept to grasp, so we recommend allowing plenty of time for discussion at the end of the lesson.

In this lesson, students will explore the creation of repetitive designs using variables in the Artist environment. Students will learn how variables can be used to make code easier to write and easier to read, even when the values don't change at runtime.

This lesson will help illustrate how variables can make programs more powerful by allowing values to change while the code is running.

In this lesson, students will explore the creation of repetitive designs using variables in the Artist environment. Students will learn how variables can be used to make code easier to write and easier to read. After guided puzzles, students will end in a freeplay level to show what they have learned and create their own designs.

Returning to loops, students learn to draw images by looping simple sequences of instructions. In the previous online lesson, loops were used to traverse a maze and collect treasure. Here, students use loops to create patterns. At the end of this stage, students will be given the opportunity to create their own images using loops.

In this online activity, students will have the opportunity to learn how to use events in Play Lab and to apply all of the coding skills they've learned to create an animated game. It's time to get creative and make a story in the Play Lab!

This lesson will give students an idea of what to expect when they head to the computer lab. It begins with a brief discussion introducing them to computer lab manners, then they will progress into using a computer to complete online puzzles.

Using Scrat from the Ice Age franchise, students will develop sequential algorithms to move a squirrel character from one side of a maze to the acorn at the other side. To do this they will stack code blocks together in a linear sequence.

In this lesson, students will use their newfound programming skills in more complicated ways to navigate a tricky course with BB-8.

Students will apply the programming concepts that they have learned to the Harvester environment. Now, instead of just getting the character to a goal, students have to collect corn using a new block. Students will continue to develop sequential algorithm skills and start using the debugging process.

Building on the concept of repeating instructions from "My Loopy Robotic Friends," this stage will have students using loops to get to the acorn more efficiently on Code.org.

This lesson was originally created for the Hour of Code, alongside the Minecraft team. Students will get the chance to practice ideas that they have learned up to this point, as well as getting a sneak peek at conditionals!

Up until this point students have been writing code that executes exactly the same way each time it is run - reliable, but not very flexible. In this lesson, your class will begin to code with conditionals, allowing them to write code that functions differently depending on the specific conditions the program encounters.

By the time students reach this lesson, they should already have plenty of practice using `repeat` loops, so now it's time to mix things up.

_While loops_ are loops that continue to repeat commands while a condition is met. `While` loops are used when the programmer doesn't know the exact number of times commands need to be repeated, but does know what condition needs to be true in order for the loop to continue repeating. For example, students will be working to fill holes and dig dirt in Farmer. They will not know the size of the holes or the height of the mountains of dirt, but the students will know they need to keep filling the holes and digging the dirt as long as the ground is not flat.

In this lesson, students will learn about `until` loops. Students will build programs that have the main character repeat actions `until` they reach their desired stopping point.
