A border of chalk dots can be drawn in a few steps. You can snap the steps as blocks. You can also write them as plain words.

Five ideas, in order.

This track is Programming with Blocks III: Bridge to Text.

What you will learn

Words. Write each block as one plain line.
Names. Give a repeated group one name.
Numbers. Hand a number to a named group.
Reading. Predict what written steps will do.
Exact text. A machine reads every character. A character is one letter, digit or sign.

Need a quick recap?

Blocks run in order. Top to bottom.
A repeat block runs the blocks inside it again and again.
A variable is a box that holds one value.
A block inside a block is called nesting.
