Edit a crowded mind map.
Five editing decisions that turn a crowded page into a useful explanation.
Five steps from a blank page to a map you can revise or teach from. It takes a few minutes to learn and one real topic to get comfortable.
Write the subject in the middle of the page in a few words: “Photosynthesis”, “First week”, “An Inspector Calls”. Everything else will grow outwards from here.
Ask what the three to six biggest parts of the topic are, and give each one a branch. Do not worry about the order yet. You can move branches around later.
Add smaller branches for examples, causes, steps or terms. Use key words, not sentences. Keep labels short enough to scan while you revise.
Give each main branch its own colour and carry it through to the detail underneath. When you look back, colour tells you which part of the topic you are in before you read a word.
Look at the whole map. Move anything that sits under the wrong branch, merge repeats, and notice what is missing. Then try explaining the topic aloud from the map alone.
