Math
Cian explored geometric concepts by programming Dot to point in a random direction, which required him to understand angles ranging from 0° to 360°. He then coded Sprite 1 to move across the stage and bounce off the edges, applying the idea of angle of incidence equaling angle of reflection. By using Pen blocks to draw rainbow lines, Cian created repeating colour patterns and practiced sequencing, recognizing how incremental steps produce a larger geometric design.
IT
Cian completed Lesson C of the Scratch 3 Programming Playground book, creating a custom sprite named Dot and using block commands to set its orientation randomly. With guidance, he built a second sprite called Sprite 1, programmed it to move, detect stage boundaries, and bounce, then duplicated the sprite and its code. He also learned the Pen blocks, applying them to draw colourful rainbow lines that followed Sprite 1’s path, demonstrating competence in sprite creation, event‑driven programming, and visual output.
Tips
To deepen Cian’s learning, have him add a variable that tracks how many times Sprite 1 bounces and display the count on screen, turning the project into a simple data‑collection game. Next, challenge him to design a maze on the stage and program Dot to navigate it using conditional blocks, reinforcing problem‑solving and spatial reasoning. Introduce a collaborative extension where Cian pairs with a peer to create a two‑player “tag” game, swapping control of sprites and exchanging code snippets. Finally, encourage him to keep a coding journal that sketches the sprite paths on graph paper and reflects on the maths behind each turn.
