Michael's math profile.

Hey, I'm Michael, and I am a grade 8 math student . If someone asked me if I like math, I would say 'kind of' because sometimes it's easy for me to learn, but at the same time hard to understand. The thing I liked the most in math class, was doing the spinners for circle graphs, and we would all guess which colour it was going to land on !

Last year in grade 7, my favourite unit we studied, was fractions, because it was really easy, and we learned how to add and subtract them. I did well in this unit because, it was very easy for me to understand what was going on, and what was going to come next. The unit I had a hard time was converting the decimals, because sometimes I would get confused.

This year, in grade 8 math, I will become successful, by studying hard and finishing all my homework and getting good grades on tests. I would like to learn more about algebra, and anything else that's new to us and become a better and smarter student for all units.

My favourite blog I did last year, was the one I first did, because it was the day we first learned how to blog and I think I improved throught the year. Blogging helped me a lot because we gave and got feedback from our classmates saying what we can do better next time. I want to do more blogging this year, and just have fun !

Define:

Variable - A letter that represents an unknown number.
Expression - Any single number or variable, or a combination of operations involving numbers and variables.
Equation - A mathmatical statment with two expressions that have the same value.

Eg. Variable a,b,c
Eg. Expression 2,x,2x+1
Eg. Equation 1+1=2, 2x=4 , 2+3=4+1


Find and describe the pattern. ID the next 3 terms.
64,58,52,46,40,34,28
Subtract 6 each time




Is this linear equation x=2y?
False backwards, should be y=2x

y=3x
Should be y=2x+1


Define:

Mean -The sum of a set of values divided by the number of values in a set.
Median - The middle number in a set of data after the data have arranged in order.
Mode - The most frequently occuring number. It can be used more than one.
Range -The difference between the large and small values in a set.
Outlier - A value that is much smaller or larger than the actual answer.
