Remember when your teacher would write a word on the board (or you'd be given a worksheet with one long word or title on it), and you had 5 minutes to see how many words you could make out of it?
Kindergarten can do it, too, but you have to adjust a few things. First off, do it as a class.
Because of the season, I used "Valentine", but I first did it using the phrase "Merry Christmas". But this is a perfect way for them to work on their letter formation skills, how to start next to the red margin in their journals, and to stay on the line. You're going to have a few children spot words they can spell. You'll also have children spell words they think are correct, but aren't real words (ex: "lite" for "light".)
Of course, once they get stuck, you can find a few more to add to their list. Be sure to use this Teachable Moment to explain what the words mean.
Above are 3 examples of my students' work.
