What is Turtle Flags

Turtle Flags presents more than 200 challenges to the learner that must be completed using basic Logo-blocks. The challenges are based on national flags.

Turtle Flags is a fork of Activities/Turtle Confusion that presents 40 shape challenges to be programmed by moving the Logo turtle.

Please refer to the Activities/Turtle Art pages for basic instructions on how to use the block interface and the details of various toolbars.

The flag challenges are loaded from the Combo Box on the Project (Palette) toolbar. When you select a flag, it will be loaded onto the canvas. When you use the Erase button, the current flag is reloaded.

The available blocks are small subset of the Turtle Block blocks: the basic turtle blocks; a reduced palette of pen and color blocks; some basic arithmetic operators; the repeat block; and the action and box blocks.

The Export palette includes save as Logo; save as image; and save as Turtle Art.

What are the challenges?

The 200+ flag challenges are problems of symmetry and geometry which typically can be solved by using a combination of fill and repeat blocks.
