"Take note" means "pay attention". "Take notes" means "write notes".

Read Rachael G's post here thoroughly. It can be either based on context and can be used in the exact same sentence but have different meanings. I'll show you how we can work through this math problem, take note how I ... I'll show you how we can work through this math problem, take notes how I ... Same sentence, add an s and they're different. First one would mean to be aware of, make sure you're paying attention, keep track of. Second sentence is a command, telling you to write down notes of what is shown next. We can't know the answer here I less we have more context, unfortunately, or heard it to determine if there was an 's'.

Take note is referring to a specific example the speaker is talking about and isn’t usually referring to writing anything. Take notes means to write get important points of something somebody is telling you about.

It depends on the teachers desired outcome… did he/she want the students to ‘take note’ during class i.e. listen very carefully to what he/she was saying OR ‘take notes’ i.e. writing down what the teacher was saying 📝 OR perhaps they want the students to ‘take note when taking notes’ which would mean being very attentive when writing notes! Isn’t it both confusing and fascinating how one letter can change the meaning completely? Reading the rest of the sentence/paragraph to pick up context clues will help in this situation.

;'take notes'' is the correct answer
