I Can Read Code

Build a project with visual blocks in Playground Engineer Studio on iPad. Then open I Can Read Code in the same app to see the instructions behind what you made.

Ask About I Can Read Code See How It Works

Create first. Then find out how it works.

Try building a pattern from one shape. Use a Repeat block to make copies, then open I Can Read Code to see how those instructions describe your pattern.

Find the repeat

Find the instruction that makes copies of the shape. Compare the plain-language steps with how the repeat is expressed in Swift.

Test a prediction

Predict what will happen if you change the number of copies. Edit the Repeat block in PGE Studio, then compare the new pattern with your prediction.

Explain the change

Look at the updated instructions and explain how changing the repeat count changed what you see on the canvas.

Basketball Game Remix in PGE Studio, with the ball’s size settings beside the hoop and score — Basketball Game Remix. Change the ball’s size in Creative Prompt Blocks, then open I Can Read Code to see how your change is represented.

Dress Up Remix in PGE Studio, with Swift code on the left and a character on the canvas — Dress Up Remix. In PGE Studio’s Swift view, find the code that adds a sticker when you tap the canvas, then find the function that builds the character’s head.

How we use the two iPad apps

In PGE Studio, students build their projects and read the code behind them. Depending on the student’s level and the project, we may also use Swift Playgrounds as a separate iPad app for coding puzzles or short Swift exercises.

The ideas you’ll practice

Follow the path from an input or event to an action. Read and call functions, see how parameters affect the result, and explain what the code does in your own words.
