As almost every parent experiences...none of their children learn the same. True in our house.
Eli could care less about any academics most of the time. He'd rather be outside building something.
Today while were were doing math, he wrote a number correctly but couldn't name it...a very common occurrence for him.
"Eli what number did you just write.?"
Eli: "I don't know."
Me: " Eli try and figure it out."
Usually he will count in his head and then he can name it. I didn't want to tell him the answer because just then I was thinking that maybe the harder he has to work he will eventually just realize he should remember it. (One of many theories I have had over time as to how I can encourage him to remember names of things.)
Eli: "That is how I try to figure it out. I just say "don't know."
(Confirmation...it is a whole lot easier to say "Don't know" since mom will just tell me the answer.)
