7、I have never learned as much math in my life as I did 1ast year. It was because of Ms. Pam 1  I truly understood what I was learning. It might not seem  2  a big deal to some, but to me it is. I have never met a woman so caring and so determined to teach her  3  .

I never really wanted to work for good  4  in math class. I never knew how to study math and never understood some of the concepts. I can remember trying to sneak out of the classroom  5  Ms. Pam caught me and yelled across the  6  , “Lauren, are you coming to extra help during lunch?” It was a nightmare…she would always  7  me with one foot out of the door, it never  8  . Even then I just thought of it as a thing I had to do. It was funny to see how everyone would be in her room during lunch and then again after school. She would  9  everyone to come every day, just so we could do our homework in  10  .

Many of the students thought of her as a bit of nag, but  11  they knew that she was right and  12  for it. Many of her tests were hard at first, but as the year progressed, so did I. I knew that it was because of her.

Even outside class, she was  13  as ever. She always wanted to know what was going on in my(and everyone else’s)life, and she was always looking out for everyone’s best interest.

Ms. Pam is a sweet woman with a sense of  14  that you just have to laugh at. When regents were approaching, she was more concerned than ever about everyone doing well. Many of her precious students  15  high, and so she  16  the same from us. Day after day there were students in the classroom  17  problems. When it was time for our big test, I knew I was ready. I walked out of that test with my head  18  . I knew that I was a  19  and Ms. Pam had made me that way. I appreciated all the hard work that she put into helping me and my fellow students. I knew that I would  20  her.

6、Not all math skills are learned in the classroom．Some of them come naturally．Consider the split-second calculations  you make when you estimate（估计）the number of empty seats on the school bus or the number of cookies in a cookie jar．

These estimates can often be done without counting．That's because humans are born with the ability to closely guess the number of items in a group．Researchers call this ability a person's "number sense"．

To see how a person's inborn number sense might be linked to mathematical performance in the classroom, psychologist Justin Halberda and his colleagues from Johns Hopkins University in Baltimore, US ran some tests．

The scientists asked 64 14-year-olds to look at images of yellow and blue dots that flashed on a computer screen for a fraction （一小部分） of a second．Each image contained between 10 and 32 dots that varied in size．

Some images contained twice as many blue dots  as yellow dots．In other images, however, the number of blue and yellow dots was nearly equal．For each image, the students were asked to estimate which color had more dots．

The scientists found a wide variation in how well students could pick the color with the most dots．

The scientists then looked at the students' math scores dating back to kindergarten．Children that performed best in the image test also scored the highest in standard math tests．The same finding held true at the other end of the spectrum （范围）．Students who didn't score well on the image test received lower math scores．

The study was the first to show a link between a person's inborn number sense and his or her achievement in formal math training．

Does this connection mean that one cannot be good in math if they have a weak number sense? Or that having a strong number sense is a guarantee for good grades in math? The answers are not clear．

While scientists continue looking at the possible links between a person's number sense and math achievement, one thing is certain: Doing lots of math homework will  boost your chances of success．
