Unit 2 6th Grade Math Videos

Sunday, December 24, 2017

The videos in this video align with the state of Georgia Math Standards.
Here are the standards that are provided on the state website.
"Understand ratio concepts and use ratio reasoning to solve problems.

MGSE6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio
relationship between two quantities.

MGSE6.RP.2 Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0 (b
not equal to zero), and use rate language in the context of a ratio relationship.

MGSE6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems
utilizing strategies such as tables of equivalent ratios, tape diagrams (bar models), double
number line diagrams, and/or equations.

MGSE6.RP.3a Make tables of equivalent ratios relating quantities with whole number
measurements, find missing values in tables, and plot the pairs of values on the coordinate plane.
Use tables to compare ratios.

MGSE6.RP.3b Solve unit rate problems including those involving unit pricing and constant
speed.

MGSE6.RP.3c Find a percent of a quantity as a rate per 100 (e.g. 30% of a quantity means
30/100 times the quantity); given a percent, solve problems involving finding the whole given a
part and the part given the whole.

MGSE6.RP.3d Given a conversion factor, use ratio reasoning to convert measurement units
within one system of measurement and between two systems of measurements (customary and
metric); manipulate and transform units appropriately when multiplying or dividing quantities.
For example, given 1 in. = 2.54 cm, how many centimeters are in 6 inches?"

In this video you will learn about the coordinate plane.

Coordinate plane
The coordinate plane is a two-dimensional surface for the purpose of plotting lines, points, and even curves.
A coordinate plane has an x-axis, and y-axis, which are used to locate points on a coordinate plane. A point is named by two numbers called an ordered pair.
The x-axis is the horizontal scale, and the y-axis is the vertical scale.
The point where the x and y axis cross is called the origin.

Video of the Day

Area of Triangle on coordinate plane

 How do you find the area of a triangle when you don't have a right angle or an altitude?. You can use the coordinates in order to find the area of the triangle
 

Video Guide
:20 Sample problem one Find the area of a triangle that is drawn on a coordinate plane
The triangle does not have a right angle or an altitude drawn
:39 Step one Identify the vertices and write down the coordinates
1:09 Use the formula  Area = Ax(By-Cy) + Bx(Cy-Ay)+(Ay-By)/2
in order find the area of the triangle
2:00 Plug the coordinates into the area formula
3:17 Simplify the formula after plugging in numbers
4:16 Answer to the sample problem involving finding the area of a triangle on a coordinate plane
