construct sentences (二).

今天学了consider这个单词，造几个句子练习练习，有不对的地方希望能帮我指出。
"considered"
This is a considered option which was made by our manager. This sentence is not correct, but I understand what you're trying to say.  You don't "make" options, but you do "make" decisions.  It would be better to say: Our manager considered the options before making the decision.
All things considered , he works perfect.    "All things considered" means the same thing as "after all" or "all in all".  It doesn't really make sense in this sentence.

For example: "He filed the papers appropriately, he cleaned up the office, he even dusted the furniture. I was nervous about hiring him, but all things considered, it was a good decision."

"considering"
Considering his age, he did not do bad at all.
His score is quite high, considering.
"considerate"
He is considerate to his wife.
"considerable"
That is a considerable sum of money.
He made a considerable success!
He have a considerable business.   You have to specify what about the business is considerable: size, fame, income, etc. 
"consider"
Our department is considering to create creating a new team for this project.

Good job!  You are definitely catching on.  These words and phrases are a little tricky.  Keep up the good work!
