​- Midari Yoo

Good job so far! Some quick tips.

• write your notes down on scrap paper or the back of your test as soon as you get it as it's fresh on your mind.

• study consistently at least 2 days before the quiz, you'll retain the information better.

Section 2: Course 1 Review

​Core Connections 1

​This section will have chapters 2, 4, 6, and 7 as separate sub-categories but one whole review. The topics are the following:

1. Ar​ithmetic Strategies and Area

2. Var​iables and Ratios

3. Dividing and Building Expression

4. Rates

Chapter 2: Arithmetic Strategies and Area

Data can be displayed visually in different formats depending on the kind of information collected.

A dot plot is a way of displaying dsta that has and order and can be placed on a number line. Dot plots are generally used when the data is discrete (separate and distinct) and numerous pieces of data fall on most values. Examples: the number of siblings each student in your class has, the number of correct answers on a quiz, or the number rolled on a die.

A bar graph is used when data falls in categories that typically have no numerical order.

A Venn Diagram is two or more overlapping circles used to show overlap betwween categories of data.

A histogram is similar to a dot plot that each bar represents data in an interval of numbers. The intervals for the data are shown on the horzontal axis. The frequency (# of pieces of data in each interval) is represented by the height of s bar above the interval, which are called bins. ​

Stem-and-leaf-plots are similar to a histogram except that it shows the indivitual values from a set of data and how they are distributed. The "stem" part of the graph represents all of the digits in a number except the last one. The "leaf" part of the graph represents the last digit of each of the numbers. Each plot needs a "key​." The place value of the entries is determinded by the key. This is important because 8|2 could mean 82 or 8.2.

​

​Displays Of Data

​Area

The area of region is the number of square units of the interior of a region. In this course, you'll be asked to consider the area such as the floor, the top of a table, other geometric shapes, etc.

To meaure the area of a region, be sure to remember these tips.

​

~ any square can be used as a unit of area - a square inch, a square centimeter, the face of a block - but depending on the object being measured, some units are more convenient and common than others.

~ to find the area of something, count the number of square units needed to cover it without gaps or overlaps.

~ if the square units you chose don't exactly fit withing the region boundaries, you need to finda wat ti determine what part of the square units are needed.

~ when the answer is being stated, make sure you include the kind of suare units used. for example, { the area of the shape was 23cm.​}

​

Chapter 4: Ratios

A ratio is a comparison of two numbers, often written as a quotient; that is, the first number is divided by the second number (but 0). A ratio can be written in words, in fraction form, or with colon notation. You'll mostly write them in fraction or colon notation though.

​

For example, if there are 38 students in a school band and 16 of them are boys, you can write the ratio of the number of boys to girls like this:

​

16 boys to 22 girls

​

16 boys / 22 girls

​

16 boys : 22 girls​

​Ratio

​

Chapter 6: Diving and Building Expressions

Mathemeticians have agreed on and Order of Operations for simplifying expressions.

​

Original expression: (10-3 * 2) *2​²- 13-3²/2+6

​

Circle the expressions that are grouped within parenthesis or fraction bar.

​

Simplify within circled expressions using the O.O's.

​

• Evaluate the exponents,

• ​Multiply and divide from left to right.

• Combine like terms { adding and subtracting first.}

• Simplify the circled expressions using the O.O as above.

​Order of Operations

​Combining Like Terms

This course uses tiles to show variables and single numbers ( constant terms ). Combining tiles that have the same area to write a simpler expression is called combining like terms.

​

More formally, like terms are two ore more temrs that have the same variable(s), with the corresponding variable(s) raised to the same power.

​

​Examples of like terms: 2x² and 5x², 4ab and 3ab.

​Examples that aren't like terms: 5 and 3x, 5x, and 7x²,a²b and ab.

​

If you aren't working with the actual tiles, it helps vizualising. Mental images can help you combine same terms. When several tiles are put together to form a more difficult shape, the area of the new figure is the sume of the individual areas, and the perimeters are all on the outside. Area and perimeter expressions can be simplified or rewritten by combining like terms.

Other notes in the chapter can be found in CC1 math notes page 47

​

Chapter 7: Rate and Unit Rate

in lesson 7.1.1 you learned a rate is a ratio comparing two different quantities.

​

a ​unit rate is a rate that compares the change in one quantity to a 1- unit change in another. For example, miles per hour is a unit rate, because it compares the change of miles in the span of an hour. If an airplaine flies 3000 miles in 5 hours and uses 6000 gallons of fuel, you can find several unit rates.

​

​Vocabulary/Helpful Terms

• ​interest rate: % of interest earned per dollar, ie. banking as an example.

• variable: a letter or symbol that shows one or more numbers.

• expression: a combination of numbers, varaibles, and operation symbols, (2x+3)-5 could be used as an example.

• term: part of the expression se​parated by subtraction and addition.

• coefficient: the numerical part of a term.

• constant term: a number that isn't multiplied by a variable.

• boundary point: solution to the equality of and inequality.​
