This week in math, we're focusing on measurement. There are some key forumlas involved in our lessons this week:
Perimeter of a polygon = the sum of all the sides of the polygon
Area of a parallelogram = base x height (this includes rectangles)
Volume of a rectangluar prism = length x width x height
Area of a triangle = 1/2 x base x height
You can use these formulas to find area, perimeter, and volume. You can also use them to find a missing dimension of a figure. For example, if you know the perimeter of a quadrilateral is 10 and three of its sides are 3, 4, and 3, then the fourth side must be 2 because 3 + 4 + 3 + 2 = 10.
These lessons in measurement will not take us long. Standard 3 is one of the shortest standards in the 6th grade math curriculum. However, we will continue to review these objectives as we get prepared for the FAST 2 in January and the MSA in March.
