Students will soon learn that events are a great way to add flexibility to a pre-written algorithm. Sometimes you want your program to be able to respond to the user exactly when the user wants it to. Events can make your program more interesting and interactive.

In this special stage, students get to build their own Flappy Bird game by using event handlers to detect mouse clicks and object collisions. At the end of the level, students will be able to customize their game by changing the visuals or rules.

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

Using a set of symbols in place of code, students will design algorithms to instruct a "robot" to stack cups in different patterns. Students will take turns participating as the robot, responding only to the algorithm defined by their peers. This segment teaches students the connection between symbols and actions, the difference between an algorithm and a program, and the valuable skill of debugging.

Using characters from the game Angry Birds, students will develop sequential algorithms to move a bird from one side of a maze to the pig at the other side. To do this they will stack code blocks together in a linear sequence, making them move straight, turn left, or turn right.

Debugging is an essential element of learning to program. In this lesson, students will encounter puzzles that have been solved incorrectly. They will need to step through the existing code to identify errors, including incorrect loops, missing blocks, extra blocks, and blocks that are out of order.

In this series of puzzles, students will continue to develop their understanding of algorithms and debugging. With a new character, Laurel the Adventurer, students will create sequential algorithms to get Laurel to pick up treasure as she walks along a path.

In this lesson, students will take control of the Artist to complete drawings on the screen. This Artist stage will allow students to create images of increasing complexity using new blocks like `move forward by 100 pixels` and `turn right by 90 degrees`.

Binary is extremely important in the world of computers. The majority of computers today store all sorts of information in binary form. This lesson helps demonstrate how it is possible to take something from real life and translate it into a series of ons and offs.

Building on the initial "My Robotic Friends" activity, students tackle larger and more complicated designs. In order to program their "robots" to complete these bigger designs, students will need to identify repeated patterns in their instructions that could be replaced with a loop.

As a quick update (or introduction) to using loops, this stage will have students using the `repeat` block to get Scrat to the acorn more efficiently.

This lesson builds on the understanding of loops from previous lessons and gives students a chance to be truly creative. This activity doubles as a debugging exercise for extra problem-solving practice.

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!

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.

Part puzzle, part word search, the Spelling Bee asks students to program a bee to find common words in a grid.

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.
