Pacing of Computational Thinker Unit by Day and Objective
Day	Objective
Day 1	Students will review the Cornerstone task requirements and the rubric. Students will begin by writing trivia questions for true/false trivia questions and answers.
Day 2	Students will rely on pattern recognition to complete the coding required to finish the maze game. They will upload the HCPSS Updated Cornerstone Maze Project in Scratch for CS First. Students will begin by modifying the given code for their true/false trivia questions and answers.
Days 3-4	Students will continue to modify the given code in their maze game, HCPSS Updated Cornerstone Maze Project in Scratch for CS First, relying on their pattern recognition skills. Using the given code and skills previously learned, students will complete the code for maze game project. When finished, students will have a maze game that includes the following requirements: the sprite moves appropriately true/false trivia questions asked at each obstacle sprite responds appropriately at each obstacle based on if/else code
Day 5	Students will pair up with a partner and play each others Maze Games. They will reflect on their coding experience by responding to a discussion post.
