In this pre-introduction lesson to computer science, students will be introduced to drag and drop. This will help ensure they are able to complete the tasks by using a mouse/trackpad by clicking, dragging, and dropping a block to the correct area. On the tablet, they will touch, drag, and drop. This is a precursor lesson.

In this introduction lesson, students will be introduced to the first concept in computer science: sequence. They will learn how a computer thinks in sequential order. They will complete simple tasks by recognizing the sequence to complete the challenges.

In this lesson, students will learn to debug, find and fix mistakes. In computer science, it is important to be persistent and problem solve through challenges. Students will have the opportunity to debug by looking for mistakes in their lines of code, think of a solution, and try it out.
