USE A DRY ERASE BOARD
You can buy a set of plastic magnetic letters at the Dollar Store. Have your child put the letters on a metal cookie sheet or the refrigerator to make the word, then read it. Later, encourage him/her to make the word, read the word, cover the word, write the word, check the word, read the word. (Children may peek at the word if necessary while they are learning to write it correctly.)
Write the word over and over until it is learned, erasing each time. This is a writing task, not a copying task. If your child is using paper and pencil, fold the paper over each time or use another paper or card to cover the previous word. If your child needs a model to start with, provide it. Then cover it and allow him/her to peek if necessary. Then remove it altogether. Encourage your child to make sure the words are in his/her head.
Make cards with several pairs of popcorn words. Scramble the cards and lay them faced down in neat rows. Turn over 2 cards at a time, read the words, and see if you have a match! Continue until all matches have been read and collected!
As you go through the stack of cards, ask your child to read in the following voices: baby, robot (monotone), goofy, scary, mad, old.
Have your child go through a poem, worksheet, decodable book, page of a magazine, or newspaper clipping and highlight the popcorn words.
Provide your child with a safe surface (preferably outdoors), with which to use shaving cream. Spray a good amount of shaving cream onto the surface, and have your child smooth it out. Your child can use his/her finger to spell out popcorn words in the shaving cream. Between each new word, smooth out the shaving cream and practice again and again!
