With a little help from the guys next door, I was able to give some great grammar examples to Joshua today.
One of the next doors woke up in a grumpy mood. We'll just call him "Bob" today. When "Joe" came out of his room for breakfast, Bob starts saying, "I hate Joe, gonna beat him up." We got Bob in another room and he seemed to calm some. But it wasn't long before Joe got up to get more cereal and Bob ran in the room and pushed him. He was quickly restrained from his physical aggression but continued to yell, curse, and threaten. We got him back into his room and gave him a little something to calm him down while Joe finished eating his Fruit Loops in as much peace as possible given the situation.
Once that Haldol kicked in and everything was okay, I came back over to our side to work on some school with Joshua. I could hear both Lowell and our day staff laughing as I was using examples such as, "If I say, 'Bob hit Joe' then Joe is the direct object. Hit who or what? Joe. So Joe received the action of the verb. If I say, 'Bob is crazy' then crazy is the predicate adjective because it describes Bob. If I say, 'Bob is a bully', then bully is a predicate nominative because it renames Bob."
I also used sentences such as, "The laundry room door is broken. It was pulled off its hinges."
It was good to use sentences that really apply to our everyday life. And guess what? Joshua understood perfectly. So sometimes living with a little crazy pays off!
