Your brainstorming notes may be in the following formats:
1. The TXTéamelo worksheet, with ¿Quién? ¿Qué? ¿Cuándo? ¿Dónde? ¿Por qué? ¿Cómo? questions, and an overall summary.
2. A "mind map" or "word web" of ideas
3. Your own format of notes and ideas showing what you have brainstormed
You can choose which format works best for you, any of the three options above will get you the 5 points, as long as you can show that you have taken the time to think through your ideas.
