[4.MD.5b-1.0] Angles in Degrees - Common Core Standard
By Freckle education
Understand that an angle that turns through n one-degree angles is said to have an angle measure of n degrees.
[4.MD.5a-3.0] Angle Measurement - Common Core Standard
By Freckle education
Understand that an angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
[4.MD.5a-1.0] Angle Measurement - Common Core Standard
By Freckle education

This lesson covers permutations. Students learn that a permutation is an arrangement of objects in which the order is important. For example, the permutation AB is different than the permutation BA. Students are then asked to solve word problems involving permutations. For example: Find the number of different ways 6 books can be arranged on a shelf. Note that the number of permutations can be found by multiplying the number of choices for the 1st position (6 books) times the number of choices for the second position (5 books), and so on. So the number of permutations is 6 x 5 x 4 x 3 x 2 x 1, or 720. In other words, there are 720 different ways 6 books can be arranged on a shelf.
[4.MD.5a-2.0] Angle Measurement - Common Core Standard
By Freckle education
Understand that an angle is measured by considering the fraction of the circular arc between the points where the two rays intersect the circle

This lesson covers adding decimals. Students learn to add decimals by first lining up the decimal points, then adding the numbers by column. For example, to add 14.2 + 2.86, first line up the decimal points, then add the digits in the hundredths column, to get 0 + 6, or 6, then add the digits in the tenths column, to get 2 + 8, or 10, so write a 0 in the tenths column and carry the 1 to the units column, then add the digits in units column, to get 1 + 4 + 2, or 7, then add the digits in the tens column, to get 1. So 14.2 + 2.86 = 17.06.

Find the value of x in the right triangle.
Area of diagonal generated triangles of rectangle are equal | Geometry | Khan Academy
By Khan Academy
In this video, Mr. Khan draws a box and two intersecting lines that produce several triangles. Mr. Khan proves that the area of these diagonal-generated triangles of the rectangle are equal. He goes over the formula for finding the area of a triangle. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.

This three-minute video is from Sal Khan about using the Pythagorean Theorem to solve a word problem: A carpet measures 7 feet long and has a diagonal measurement of square root of 74 feet. Find the width of the carpet Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly.
