How to teach Spanish in Different Contexts.
It really helps kids to learn a word/sentence in different contexts, so I wanted to give you some ideas of what contexts you could use. I will use the Tree poster for this example:
1.- Real life: Go through the audios right by a real tree.
2.- Printed image: Go through the audios as you point at the parts on the poster.
3.- Dramatic play: Dress your child or a doll up like a tree and go trough the audio as you point a the tree parts on your child/doll.
4.- Toys: Use legos to make a tree or use a plastic tree to point at the tree parts as you listen to the audio.
5.-Imagination: Ask your child to imagine there is a tree in the living room, "draw" with your finger the shape of the tree and then go through the audio as you point at the imaginary parts. I only recommend this context once your child is very familiar with the audio and tree parts.
You can choose any of the first 4 to introduce the lesson's words/sentences and then use any of the other ones to review. You can review the vocabulary as many times as you want, just like when you taught English to your child, you taught him how to say tree and then would say the word whenever you see, hear or read the word tree. You can do the same with Spanish, whenever you are reminded of something you have already learned, pull out the audios and practice it again, that way you keep using what you already learned.
I like to introduce vocabulary with a real life or printed image and then review with any context. You don't have to do more than one context a day, it can be too much, but rather use it to review/practice what you have learned, not just during the time you are doing the unit but for as long as you are learning Spanish.
