Do you have students that are having difficulty with certain sight words?
Do you have a district mandated list you need to use?
Do you need to differentiate for kids in R.T.I. who need remediation?
Or maybe you need to enrich your students who already know all of your words and need more challenging ones.
You could spend hours searching and pulling out the cards you need. Or you could use the Editable memory game and type in the words you need. Type them in one time-- and the cards will make themselves.
Print them in color.
Print them in black and white to save ink.
Make different lists to differentiate centers by printing on different colors of card stock- or by naming your sets and printing the backs to the cards.
Either way you can tailor these cards to be exactly the way you need them. Then you can change the words and do it all over again!
