Students with ASD can often have a hard time with abstract concepts. When teaching these concepts, it is often useful to try and make them more concrete then generalize the skill later on. These worksheets offer a great way to teach the concept of "yes" and "no". Simply cut out the photos from page 3 and paste them into the worksheets - there are two of each animal. Make some of them match so the answer is "yes", and choose non-matching photos so the answer is "no". After you have setup the worksheet, have your student go through and circle "yes" or "no". You can also cut out the "yes" and "no" visuals and use in other activities to help generalize the concept!
