Imagine trying to build a giant treehouse by hammering random boards together without measuring anything first! The whole house would probably wobble and crash down.

To create things that actually work, engineers and coders follow a 5-step guide called the **design process**.

How do we start whenever we want to make something new?

First, you must ask questions so you know the exact problem you need to solve.

For example, if your puppy gets soaked outside when it rains, your problem is: **"My puppy needs a safe, dry shelter in the yard."**

Now that you know the goal, what should you do before grabbing your hammer?

In the **plan** step, you brainstorm ideas, sketch drawings, and list the materials you will need.

Once your plan is ready on paper, how do you bring it to life?

In the **build** step, you follow your plan to construct your project using tools, blocks, or computer code.

You put the wooden walls together and attach the slanted roof just like your drawing showed.

Your doghouse is standing, but how can you be sure it actually keeps the rain out?

In the **test** step, you try out your creation to see what works and what breaks.

If you spray the doghouse with a garden hose and water drips inside, you **improve** your design by sealing the roof cracks.

Great builders remember: testing isn't about being perfect on the first try—it's about learning how to **improve**!

What Is a Design Process?. Learners will list the steps of a simple design process: understand the problem, plan, build, test, and improve.

The Engineering Song | Ready Jet Go! (Grades K-2)

Code.org Computer Science Fundamentals: Loops in Collector & Drawing with Loops

Elementary Engineering Design Process: Ask, Imagine, Plan, Create, Improve

When introducing the design process to 2nd graders under TEKS 126.3(b)(2)(B), connect physical engineering activities (unplugged card towers or mazes) directly to algorithmic coding (block loops). Emphasize that 'Improve' is where true learning happens through debugging. Use kinesthetic chants, sequential movement games, and visual anchor charts to reinforce the order of Understand, Plan, Build, Test, and Improve.

Step 1: Understand the Problem

Step 2: Plan
