Ysabelle's Estimating Square Roots

ESTIMATING SQUARE ROOTS

Page 99 # 8 & 9

8)
Q: Identify all possible whole numbers with a square root larger than 2 and smaller than 3.
A: All possible whole numbers with a square root larger than 2 and smaller than 3 are 5, 6, 7, & 8.
√5=2.2 √6=2.4 √7=2.6 √8=2,8

9)
Q: What are possible whole numbers that have a square root between 4 & 5?
A: All possible whole numbers that have a square root between 4 & 5 are 17, 18, 19, 20, 21, 22, 23, & 24.
√17=4.1 √19=4.3 √21=4.5 √23=4.7
√18=4.2 √20=4.4 √22=4.6 √24=4.8

Part 1

Ratio - compares quantities measured in the same units.
Two - Term Ratio - compares two quantities measured in the same units.
ex. 2:3, 7:10
Three - Term Ratio - compares three quantities measured in the same units.
ex. 2:4:7, 5:8:11

Rate - compares two quantities measured in different units.
Unit Rate - a rate in which the second term is one.
ex. 2hr/km, $1.80/pen
Unit Price - a unit rate used when shopping.
ex. $56/kg, $7/L

Proportion - a relationship that says ratio and rate are equal


Ysabelle's Math Profile

Hi, my name is Ysabelle. I am a Math student in grade 8. If you're gonna ask me if I like Math, I would answer- yes, a little bit. I love Math because it helps me a lot, in many ways. I'm not very good at it but I really love solving Math problems. It develops my skills and I think makes my mind sharper. The best thing I ever did in math class was when we factored polynomials when I was in first year high school(it's like grade 7 here in Canada). Factoring polynomials, for me was really fun.

In grade 7, the best unit I studied was the unit on Cartesian Planes. I still remember how to find slopes then graph them. I really liked this unit because I really had so much fun graphing and solving problems involving slopes. I really did well in this unit because it really was pretty easy. The unit that made me struggle was the unit on special products and binomial expansion. I really got confused in this unit. I had a very hard time expanding binomials. It will really take a lot of time for me to expand binomials. I really hate to expand binomials especially when they're in the seventh power or more. I also had a hard time in special products because I got confused in many things. Too many to mention. I will study very well this year so I don't have to struggle anymore.

This year,in grade 8, I will study very well and developed my Math skills to be a successful math student. I will also do my homework. I will be a responsible student and do the things I have to do. I want to learn more about Algebra this year.
