Letter Recognition Activities - Matching Upper and Lowercase Letters using paper cups, and lots of other fun activities. There are several really good ideas for centers here that would be perfect for students with special learning needs.
Moederdag/grootouderdag DIY: Great project for teachers to do in art class, kids to do at home with parents or grandparents for Mother's day or any day! Cut paper relief sculptures in tin can planters.
Drawings of the same snowmen face or part of the face from different points of view: front, side, above, from underneath, upside down etc. Colored with oil pastels. Outline everything with black oil pastel.
My teacher uses a Noise Meter similar to this one. The Noise Meter is a cool way to remind students the correct noise level that they should be using! You just use the paper clip and move it to the appropriate noise level the students should be using.
