that is a rather harsh word to use - normally autistic learners need more  time to explore and experience their environments.  perhaps he is tactile defensive or has sensory issues which prevents him from wanting to cut, colour and paste.  he should be eased into these types of activities.  i do think that you could help him along with the tasks and gently hold his hand to guide him along.  i would reward every effort he makes to eventually do the task on his own.  be encouraging and use positive reinforcement to get the desired effect. children learn through play so make his learning experience fun.

Autistic Children need extra help for understanding and fine or gross motor activities.
First see what things does a child like. Any favorite food, color, TV characters etc.
Then based on that plan the activity- color his favorite character, or get
favorite food as reward.
You could also take the child for Occupational Therapy and a professional therapist could find his areas of needs.

Sorry for using the word lazy, actually I really didn't mean it that way, I think he is not lazy he just doesn't want to do any learning thing. He might be tactile defensive or he might be finding the tasks hard even it looks easy for others. I tried everything(positive reinforcement, helping little bit) and he still doesn't want to cooperate. There is something that prevents him working with any single learning thing. I wish I knew what it was and how to help him.

Thanks for taken LAZY back. I have an 11yr old ASD child who appears "lazy" according to family members but, once you put something infront of him that peeks his intrest he will go to town. I myself have found LEAPFROG items to be very helpful. Also he might need a O.T. and P.T. screening done. My son has hard time holding a pencile to write so its not his thing. Today we tried cutting flash cards and he asked for help because he was cutting jagged and he cldnt hold paper n scissors. Parent to parent take a deep breath count to 10. It will come but slowly. 11yrs old 5th grade, grade K accidemics. Remember they live in their own world and life is a struggle try not to make it harder by loosen your patience.
