When we talked about cause and effect last week we used some dominoes to help the kids make a connection to what I was talking about.
The marble or my finger hitting the dominoes was the cause and then the dominoes falling over was the effect. This would be a skill that you could easily ask them questions about not just in their books but in everyday life.
What caused us to eat dinner? Why did you get ready for bed? Why did the kid take a shower? Why did the girl get grounded? Why did the car stop?
