Today we’re exploring Coding and Computational Thinking!
Computational thinking means solving problems like a computer — by breaking them into steps, spotting patterns, and giving clear instructions.
We’ll learn simple algorithms, loops, and how coding connects to math. Let’s have fun and create! 💻🚀
1. What is Computational Thinking?
It’s like being a detective and a chef at the same time!
• Break big problems into small steps (Decomposition)
• Spot patterns
• Create step-by-step instructions (Algorithms)
• Think logically and fix mistakes (Debugging)
2. Algorithms – Step-by-Step Instructions
To make a peanut butter sandwich:
1. Take 2 slices of bread
2. Spread peanut butter on one slice
3. Spread jam on the other slice
4. Put the slices together
5. Eat!
3. Loops – Repeating Actions
Repeat 5 times:
Jump up and down
Clap your hands
In math: Print the numbers 1 to 10 → Use a loop!
4. Conditionals – Making Decisions
IF it is raining THEN
Take an umbrella
ELSE
Wear sunglasses
5. Let’s Practice Together! 🎉
Question 1:
Write a simple algorithm to brush your teeth.
1. Wet toothbrush
2. Put toothpaste on it
3. Brush for 2 minutes
4. Rinse ⭐
Question 2:
Write a loop to print numbers from 1 to 5.
Repeat 5 times: Print next number ⭐
Question 3:
If you have more than 10 cookies, share with friends. Write as a conditional.
IF cookies > 10 THEN share with friends ⭐
Question 4 (Math Connection):
Write a rule (algorithm) to find the next number in: 3, 6, 9, 12, ...
Add 3 to the previous number ⭐
6. Real Life in Canada 🇨🇦
Following a recipe to make butter tarts
Planning the best route to school (algorithm)
Repeating warm-up exercises in hockey practice (loop)
Deciding what to wear based on temperature (conditional)
You are a Computational Thinker! 🏆💻
Amazing work today! You now understand algorithms, loops, and conditionals.
These thinking skills help you in math, science, and everyday life.
I’m so proud of you!
