For this center, I took two large foam dice and covered each side with a sticky label. On the red, I put the two vowels we have been practicing, and the blue die has the consonants we have working on. I LOVE using dice because the precious ones love them! So, they roll a consonant, roll a vowel, and then choose a letter from the box on their page to make a word! Here is the page (available at my Teacher's Notebook shop)
Another center we are doing is the tried and true playdough word tracing for our sight word centers. I ask mine to roll out the dough into "snakes" to use as lines when forming the words, as opposed to just smashing the dough down in any old way. This helps them see how the letter is formed.
I'll keep 'em coming!
