So, what exactly is a Mistake Book? It’s a notebook where you log your language mistakes using a structured approach. Each page is divided into three columns: • Column 1: The Mistake – Write down the mistake exactly as you made it, whether it’s in speaking, writing, or grammar. • Column 2: The Correction – This is where you write the correct version of the sentence or phrase. • Column 3: The Explanation – Briefly explain why it’s a mistake. Keep it concise—just enough to remind you of the rule or reason behind the correction. For example, if you wrote “I have went to the store” instead of “I have gone to the store,” the explanation might be: "Use the past participle ‘gone’ instead of ‘went’.’"
