"Think, Then Think Again…"

This is a video I made about the two different bowing techniques, marcato and legato.  Enjoy!

We need negative numbers because they are important in our life.  Negative numbers are important, because without them we can’t express temperatures below zero degrees, people’s debts, meters below sea level… and more.

This is my iMovie that I created during math.  We are learning about algebraic expressions.

Watch the movie to learn how and solve an equation.

At school, we are studying the differences between the Neolithic era and the Paleolithic era.  Here are two acrostic poems that I wrote about the two different time periods:

Paleolithic Era

Painted caves for religious purposes

Already walking on two feet

Lived in skin tents and caves

Everyone was busy to keep themselves alive

Only gathered plants, not grow them

Traveled from place to place

Hunter and gatherer were their jobs

Ill people normally weren’t properly treated

Clans of about 60 people were formed

Evolved from astralopithecus afarensis

Raising animals was not done yet

Always moving from place to place

Neolithic Era

Needed the help of domesticated animals

Educational systems were started by them

Ore was a valuable resource, wanted by all

Lots of people were farmers

Involved in the business of agriculture

Trading in far out places

Houses made out of mud bricks with tools

Interested in finding ways to make life easier

Communities were as large as 30,000 people

Everyone in the community had a specific job to perform

Resourceful in many ways

A huge part of our history

Explain why 4+y is an algebraic expression.

Give an example from your own life of a constant and a variable.

A constant is a value that CAN NOT change.  A variable is a symbol used to represent a quantity that CAN change.  An example of a constant variable can be my brother, Carlos’s age, 10 years-old.  His older sister, Isabelle, is 3 years older than him (and always will be).  Let’s say that the symbol k represents Carlos’s age.  Isabelle’s age will always be k+3.  This means that if Carlos (k) was 56 years old, I would be k+3, otherwise known as 59 years old.

At school, we had to write an encyclopedic entry about archaeology.   Here it is:

Archaeology

Archaeology is basically the study of our history.  Through it, the world slowly uncovers  more about the past and learn more about us and our surroundings.  Archaeologists are the experts on this subject,   however, there are also others who are specialists in other fields that help, when trying to find out more about our ancestors.  Say in the middle of an excavation an archaeologist finds an unusually big crack on the ground.  Who would he/ she turn to for advice?  Definitely a geologist would be his/ her first choice for the best results.  Another example is if an archaeology team was digging and he/ she found an artifact with weird writing on it.  Who would they contact?  No doubt a linguist would be their first and best choice.  Otherwise, a linguist is not really much help; they can’t contribute much when it comes to finding out more about our prehistory.  What a bummer for those linguists.  Another scenario is: suppose, on a site a team spots a mysterious flower poking out from the ground, who would they contact?  Ordinarily, a botanist would be their first pick.  If by any chance, the same, very fortunate team found fossils and artifacts in a sarcophagus, they would surely contact a paleoanthropologist to help them out; then maybe a chemist to help them conserve the fossil.  Besides a specialist, another source that might help out when searching for information would be a secondary and primary source.

  At school, we had a writing project to write an essay about how marvelous an oreo is.  Well… here it is:

Ode to Oreo

            In the year of 1912 it happened… the Oreo was DISCOVERED.  After 97 years of pure Oreo happiness, the world is still in love with the cookie. 

            I, myself, a lad 11 years old appreciate the amazing brains of Nabisco very much.  I recall my first moment with the Oreo.  It was a rainy day out, and I was very young then, also very picky about what went into my mouth.  When I spotted my mom dipping an Oreo into a glass of milk, while staring out the window with a blank expression as if thinking very profoundly, I immediately shouted across the room, “GIMME, GIMME!”  Before my mom could even look away from the window, I was already beside her examining a cookie.  The outer coat of the sandwich cookie was not only filled with designs, which felt like African cave painting, but also what smelled like rich, creamy chocolate.  The texture of the Oreo felt bumpy but pleasant.  It reminded me about mountains, rocky but still enchanting.  The cream in the middle looked sweet and scrumptious.  The cookie reminded me about the stars out in the deep, deep galaxy.  I took a quick whiff from the cookie, and it automatically charmed me, making me want to eat it.  I glanced over at my mom and watched how she ate the Oreo.  She would separate the top chocolate cover form the bottom absent mindedly but carefully.  Then she would lick the covers off till they were cream free.  I watched her with deep interest and licked the sweet cream off, too.  The rich taste of the sugary goodness made me want to eat at least a dozen or two more.  After the first step of luscious crystal gooey goodness, I couldn’t resist but to follow my mom, by dipping my cracker pieces into the glass of milk then listened to the soft crunching in our mouth’s.  I realized it tasted like an explosion of chocolates:  Hershey’s, Cadbury, Dove, Ferrero Rocher… and many more, but better.

             From then on, I knew that I’d finally found my true love.

Q1: What do you know about equivalent fractions?

A1: I’ve learned that if you multiply/ divide  the numerator and the denominator by the same whole number in fraction form you can get an equivalent fraction. 

For Examaple:

You can multiplay.  1/2 x 5/5 = 5/10.  They are both equal.  You can also divide if they have common factors.  80/100 (/) 2/2 = 40/50, those are both equal.

Q2: What do you know about fraction operations?

A2: I know that in order to solve a division problem, you have to  make the divisor into its reciprocal form.  Then proceed as in multiplication.  I also know that when you multiply you don’t need to make like denominators, you just multiply denominator by denominator and numerator by numerator.  But with addition and subtraction you have to make like denominators.  Then just add the numerators.
