This is an 8-page receptive language worksheet designed to target the concepts of same and different. I've found that many children with autism can match, but they may not necessarily understand the concepts of same and different.
I've designed the worksheets to target one of these skills at a time with 6 rows of pictures per page. The first row of pictures can be demonstrated as an example, and then the students can attempt the following 5 rows on their own, making it easy to calculate the percentage of accuracy.
The first pages of same and different were designed to make the answer more obvious. For example, the longer row of the same pictures makes the "different" picture stand out. As the students are ready, I present the subsequent pages as the rows gradually get smaller to make the answer not-so-obvious. Check out this product and hopefully you'll see what I mean!
