Ever thought "The Very Hungry Caterpillar" could munch its way through code? Well, buckle up for a coding journey! We're bringing the book to life, programming our caterpillar friend's feast. This adventure will span several classes, around 6 hours total, but hey, if we're having too much fun, who says we can't extend the fun? Let's dive in and see where our coding caterpillar takes us!

Supplies

Kibo Robots, coding blocks and light bulb attachment

Step 1: Read the Book Together

We read The Hungry Hungry Caterpillar together. Once done I asked, "How is the how caterpillar looked at food like a program?" Answers included, there was a pattern; he was born, he ate, made a cocoon, and then became a butterfly; he ate more food each time, etc.

I told the students we were going to use the repeat block and change the variable of times repeated each time.

Step 2: Definitions

TO DO: Ask students for a definition of a pattern.

Possible answers: something like shapes or numbers that repeats the same way

SHOW: Attached slide,

TO DO: Ask students if this is a pattern or something else?

Answer: The above is a pattern, but it's also a sequence, because there is a pattern, the numbers grow each time, but the fruit changes each time.


Have students attempt to create a sequence with their KIBO blocks.

I pair students up so they have more blocks which makes the sequence more apparent.


Step 3: Whole Group Debugging

After two class periods of tinkering away, I start the next session by projecting our work and leading a discussion on its accuracy. We identify any hiccups in the code and troubleshoot together. Then, it's time for students to put their coding skills to the test as they program their own robots.


Differentiation: If any students are struggling with any aspect of the project, I may pair them with someone rather than working alone.

Step 4: Sequencing Together

Today, we revisit the story to clarify the distinction between patterns and sequences. After reading, I project sequence pictures and we assemble the coding blocks collaboratively. Next class, I'll jog their memory and let them take the reins, scanning the blocks themselves. Let's keep the learning journey flowing smoothly!

Step 5: Share

I've discovered that this step is crucial for my younger students. They absolutely love celebrating their successes, especially with such a potentially long term project. Once they've achieved their goals, if time permits, I'll have them line up their robots and press start together, creating a mini parade of accomplishment. It's a joyous moment that really boosts their confidence and camaraderie!
