By the way nobody is paying me to tell you this stuff. :)
Category Cut-ups: Relatively inexpensive. Great for homework. Gets the kids involved.
Descripto Bingo: I copied each category in different colored cardstock and got it laminated. It's a great way to reinforce what has been learned and it's also fun to play with any client.
Basic Concept & Vocabulary Round-Up: Not only great for categorization but also basic concepts/prepositions. Nice! Also has clearly laid-out teaching plans which I quite like. Why re-invent the wheel, right?
Classifying Cards: Oh the possibilities! Of course you can have the child sort these into piles. I liked Jenna's idea of using one of these for sorting purposes. Which One Doesn't Belong? Matching. Memory. Go Fish. Fishing. Tape them on the wall and use a flashlight to find all the cards in the right category. Hide them around the room.
Can't leave LinguiSystems out! They always have great stuff too. The pages can be copied for the child to complete or they can be read outloud by the therapist and done orally. Both gives good practice.
I know there are tons of materials out there but these are some of my favorite. What are yours?
Next time we'll talk about what to teach after categorization. I'll have another printable for you too! :)
