Math Standard 3: Knowledge of Measurement

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.

Bank of Ridgecrest

The Bank of Ridgecrest is now open and taking deposits of Rocket Rewards. The Bank of Ridgecrest offers 5% interest compounded monthly. Today in class we went over how multiplying decimals and compounding interest affects the amount of money you have. Can you say in your own words how bank interest and compounding interest works?

Multiplying Decimals

This week, our focus in math is on multiplying decimals. You should multiply decimals the same way you multiply whole numbers. To place the decimal point in the product, first count the number of places in both factors. Place the decimal point that many places from the right in the product. For example,

0.028 x 0.4 = 0.0112

There are three digits to the right of the decimal in the factor 0.028.
There is one digit to the right of the decimal in the factor 0.4.
So, there are four digits to the right of the decimal in the product 0.0112.

Can you think of times in real life when you multiply decimals? We've had plenty of examples already in our star problems. KF
