Python Creative Coding in Google Colab (Part 2)

Exceeded expectations — my 12-year-old enjoyed creating small creative programs and picked up problem-solving strategies using loops and lists. The blend of functions and Turtle animations made coding feel like play while building real skills.

Math Olympiad Summer Camp — Introductory Problem-Solving

We signed up our 14-year-old for this introductory camp and were pleasantly surprised by how much they engaged with the material. The mix of warm-up puzzles, pattern and algebra practice, and strategy sessions kept things varied, and the collaborative problem sets encouraged group thinking rather than just solo work. Each 55-minute lesson felt focused and purposeful, and the emphasis on methodical problem breakdowns built confidence even without prior experience.

Python Creative Coding in Google Colab (Part 2)

Well-structured four-week course that expanded on core Python concepts with creative projects in Google Colab, though my kid found one session per week made progress a bit slow.

Python Creative Coding in Google Colab (Part 2)

Solid introduction to more advanced beginner topics like dictionaries and nested conditionals, and the project emphasis felt meaningful. I would have liked a few extra exercises between the weekly lessons to help my child practice.
