Here are some examples from calendars I had:
How cute are these puppies? Aside from being adorable, check out their faces. You can use them for describing emotion, describing how you think they would/should feel in different situations (remember, you have 12 pictures!). You could use them to teach adjectives as well: sleepy, playful, spotted, etc.
I found the calendar above at the dollar store. In each picture, some of the friends (a giraffe, bear, duck, and bunny) are pictured doing different actions. These pictures are great for sentence formulation, describing a scene, describing weather, etc.
Have you re-used calendar pages in therapy? Tell us about it!
