Hello! Welcome to Mary's math wiki page!

One thing I love to do in math class is making foldables and drawing monsters!

Here is my animal story from math class!

The Cobweb Coat

by Mary Harris

“Bam! bam! and then bam I was in a cage!” I told my story to Puffy. “Very descriptive Fluffy,” I hated Puffy’s sarcasm. “I’m serious! That’s all I remember. It was horrible.” “Pipe down!” commanded Puffy. “What? Why?” I squealed franticly “I can hear the math teacher.” “Ok.” I stopped and listened “The base is on the bottom and the exponent is on the top. The exponent can also be called a superscript. Evaluate six to the seventh power.” “Oh that’s an easy one” chirped cricket. “Ok, answer it,” Cricket’s room mate Cricky responded. “Ok, I will, it’s 279,936.” “Ok, so you can multiply,” Cricky confessed “But I can simplify. Watch this.” “ Solve the expression 4x times 8x divided by 3b.” The teacher commanded her students. “Ha ha I’ve beaten you now Cricket.” “We’ll see about that Cricky.” “Stop bickering you two,” scolded Puffy “And start competing.” I was surprised. Puffy usually is well mannered and would never respond to a fight he wasn’t a part of. Well, he’s part of one now. I guess I would have to step in. “Whoa, whoa, hold the bird! You guys are really smart, you guys don’t need to compete to show it,” no one listened so i guess I’d have to go along. “Ok, whoever wins gets my cobweb coat.” “You wear a coat?” Puffy sounded surprised. “Yea, I’m not really white I’m brown,” “Oh, I was wondering how you stay camoflage around birds.” “Well, that’s why, now can we get moving? The praying mantis is giving Cricky that look again.” After that all there was, was term, and like term and lots of other words i didn’t understand especially the negative number equations, those always stump me. “And the final question goes to Cricket! If you get the answer wrong, Cricky shall win the cobweb coat, but if you get it right the coat is yours.” “I had no idea how good an announcer Puffy was! “and the question is: -8 divided by 24 (6 multiplied by 5) equals…” Cricket was hesitant but answered with: “ninety?” “And the answer is … correct!” I pulled the velvety web off my slim and spiny body. “Ok Cricket, here is your prize,” that little insect leaped around playing his fiddle and said “Give the coat to Cricky, it’s too girly for me. Cricky eyed Cricket for a while to see if he would take it back, but he didn’t. I guess pride is the best prize there is.

the end.

GCF and LCM Project Mary Harris

The difference between prime and composite numbers is that prime numbers can only be divided by one and itself to keep the answer whole. So like 7 divided by 1 and 7. Composite numbers on the other hand can be divided by multiple numbers. For example, 10 can be divided by 5, 2, 1, and 10.

what is a factor?

a factor is a number that is multiplied to make another number. For example, 6 multiplied by 7 is 42. 6 and 7 are the factors, they were multiplied to make another number.

what is a prime factor?

prime factorization is just organized prime factors. prime factors are factors that are prime. so like 3 multiplied by 2 equals 6. 2 and 3 are factors of 6 that are prime. prime factorization would look something like this: 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, and so on

what is a multiple?

a multiple is when you multiply a number by an integer. so it would be like 6 multiplied by 2 equals 12. 2 and 6 are multiples of 12.

what is a GCF (greatest common factor)?

a GCF is the greatest and most common factor. it must go into more than one number evenly.

what is a LCM (least common factor)?

a LCM is the lowest and most common multiple. that means 5 and 4 for example are the lowest and one of the most common pair of multiples.

18, 24, 32, = LCM is 288, GCF is 2

(my computer doesn’t let me copy paste the picture)

Reflection:

you find the LCM and GCF at the same time in the same method.

the greatest common factor and the lowest common multiple are extremely different starting with what they stand for. greatest and lowest are exact opposites and factors and multiples aren’t the same either, similar but different.

math riddles: (answers in red)

you have three triplets, two twins, and four quadruplets, how many people do you have?

nine

there are four people and a river and one canoe. these four people need to get to the other side within seven-teen minutes (they all have to be there and press the non self destruct button or else the world will explode). there are only two people per canoe. one person takes one minute, another person takes two minutes, another person takes five minutes, and the other person takes ten minutes. how do they get across?

1min. and 2min. go across (2 min.), 1min. comes back (1 min.), 5min. and 10min. go across (10 min.), 2min. comes back (2 min), 1min. and 2min. go across (2 min.), press the button and saves the world.

there are eight balls. one ball weighs more than the rest. there is one scale, you can only use it twice. how do you find the heavier ball?

you take six balls and put three on each side, if they are even you throw them out and weigh the other two, OR you take six balls put three on each side and one weighs more, you throw out the other three and put two of the other three on it one weighs more voila! OR they weigh the same, you would be holding the heavier one.

my measurements:

height: 60 in.

arm span: 60 in.

lower arm length: 9 in.

foot length: 9 in.

head circumference: 22 in.

ear height: 2 1/4 in.
