Museum of Modern Art
Last Saturday I went to the MoMA with my friend in New York City.
I went on a kid’s tour where we looked at paintings and they asked us what tools the artist would use.
It was fun but I didn’t learn that much.
At the end there was a little playroom we played in.
At the very end we went to get lunch in a Burger Joint.
When we got home I visited my friend’s house.
More Algebra
Now I am studying Polynomials.
Here is an example:
6x2 – 7x + 1
Here is another example:
10x5 + 4x4 – 13x3 + .52 – 102
Each part of a Polynomial is called a Monomial. My dad calls them “terms”.
The number in front of each term is called a coefficient.
The little numbers above the x’s are called exponents.
When x-terms have the same exponent they can be easily combined by adding their coefficients.
For example:
3x4 – 17x4 = -14x4
(-1/3)x5 + (1/2)x5 = (1/6)x5
Two terms or two monomials, make a “binomial”. (Bi – means two).
You can also multiply, divide, and factor Polynomials
Car Racing
Last week was my first Pinewood derby.
The Pinewood derby is where you make a wooden car then race it on a ramp.
I won 1st place in my den but I won 3rd against all the Tiger Scouts.
This is my video of my first Pinewood derby ↑.
Linear Equations
In algebra now I’m solving some equations with 2 variables.
For example:
x + y = 10
Here are some of the solutions to this equation:
(1,9)
(-3,13)
(9,1)
(1.5,8.5)
(13,-3)
(1000,-990)
(0,10)
(-33.2,43.2)

As you can see there are infinite solutions (x,y) to this equation. In fact, there are infinite solutions to any equation with an x and y.
The best way to describe these solutions is with a graph.
This graph is always a straight line that extends in both directions to infinity.
The easiest way to draw these lines is by computing the x and y intercepts.
All you have to do is set x equal to 0 and solve for y. Then set y equal to 0 and solve for x.
Then you have two points that you can connect to draw the infinite line!
For example, the intercepts of x + y = 10 are (0,10) and (10,0).
The other common way to graph a line is with slope-intercept form: y = mx + b where m is the slope of the line and b is the y-intercept.
Universal Theme Park
I went to Universal Studios 2 weeks ago in Orlando with my Dad and my sister.
There are 2 parks – Universal’s Islands of Adventure and Universal Studios Florida.
I was there for 8 hours!
I had a lot fun.
These were my favorite rides:
- E.T. ride
- Woody Woodpecker ride
- The Simpsons ride
- Jimmy Neutron’s Nicktoon Blast
- Flight of the Hippogriff
- Pteranodon Flyers
This picture was taken in the Wizarding World of Harry Potter.
Yesterday I went to the Miami Seaquarium with Dad and my sister.
It is in Florida on Key Biscayne.
I saw 4 shows : the top deck Dolphin show, the Flipper show, the Sea Lion show, the Killer Whale show.
I liked the the Sea Lion show the best because it was very funny.
They even had Crocodiles that slept with their mouths open!
They had a little playground.
There were also sharks and stingrays.
My Dad and my sister fed the stingrays with shrimp out of their hands.
