A big part of the CELTA was a focus on working from Meaning. So the first thing to do when teaching (well OK the FIRST thing to do is grab the students attention) but then whenever going over new vocabulary words there's a road-map of sorts that they give you. I have found it super helpful, so maybe others will find it a nice review. This works with ANY level you are teaching.
Meaning- Tell a story, show pictures, use a song, use smells, bring in realia, bring in movie clips do anything you can to SHOW the meaning of the words you are going to work on (this works best if the words are all grouped somehow). With preschoolers maybe this means you are showing a video of Arthur the aardvark at school. With older students you are asking them about their weekend and hinting at all of the theme of your lesson.
Pre-Teaching Lexis- The words you have selected to teach should be words that you don't think they know, but give them some credit. Start the draw and tell but don't tell them what each thing is, have them guess. "Struggle" with a word and see if they can guess what it is. Play hang man. Scramble the word. Play password. Etc.
Text- Finally introduce them to the text where they will see the words used. This can be a reading, or audio. They may want to circle the vocab words and see if it matches what they think it means. They can also listen to the story to make sure it makes sense.
Language Focus- Ask some concept check questions to see if they understand the questions. Have them do chants if they are younger or choruses if they are older and need the pronunciation help. If they have a word journal now is a good time to have them add to it.
Controlled Practice- This is when they have a gap fill or word to definition match, TPR, following of directions, fix mistakes, answer specific questions (adding details), some simple pair games (more complicated ones are free practice), Songs
Free Practice- This is a LOT more fun. Have them draw the picture, make an rhyme,
make them practice sentences and pictures, answer open questions etc.
