# What I learned in 6th Grade!

## Ratio's!

There are two different types of ratios, part to part and part to whole. Our classroom ratio was 14:14 if you were doing a part to part because we had 14 girls and 14 boys. Our part to whole would be 14:28 because there is 28 kids total and 14 of them are girls.

## Rate!

Rate is a ratio with units. For example you couldn't use 4 red apples to 3 green apples because it does not have MPH or Miles Per Hour. A good example would be

You are in a car for 4 hours and you drive 400 miles. What is the rate at which the car is traveling per hour. The answer would be 100 miles because you take the number of miles traveled and divide it by 4 (the number of hours).

## Unit Rate!

Unit Rate is similar to rate but it uses different things like how many beads you can put on a string or how many apples you can eat. The difference between Rate and Unit Rate are that Rate can only use MPH and unit rate Doesn't use that.

## Measurement Conversions!

Measurement conversions are when you take something like a foot and change it into inches or you take one measurement and change it to another measurement.

## Decimals!

Decimals are those dots you see in your numbers (9.1). There are lots of things that you can do with decimals. Addition, Subtraction, Multiplication and, Division.

Tip: when you read a number out loud like 9.1 you read it like nine and one tenth. It really annoys your teacher when you say nine point one

## Positive Integers!

Positive integers are whole numbers greater than zero.

## Negative integers!

Negative integers are whole numbers less than zero.

## Inequalities!

A inequality is really easy to learn. Their are a few different things to know about them though. For example the is a bunch of different symbols used for inequalities like <,>,≤,≥ and, =.

## Right Triangles!

A right triangle looks like the picture below.

## Percents

A example of a percent is

50%, 100%, 75%

You may see them at a grocery store.

## Greatest Common Factor

This is were you just find the two numbers GCF.

## A rectangular prism!

A rectangular prism is a 3D shape of a rectangle.

## Statistical Question

A Statistical Question is a question that has a answer that varies. So if you ask a question and you can only get one possible answer then it is not a statistical question.

## Set of Data!

What is a set of data? A set of data is exactly what it says in the name, a set of data.

## Mean and Median!

Mean: The mean is the average of the data set.

Median: The median is the middle number of the data set.
