We are #1 in Math Olympics!

Volumes

My Kids are creating their own building and calculating the volumes.

Extra work

Hello kids; this is an extra activity you can do at home if you want to practice everything related to areas. You must go to www.thatquiz.org and type the following codes depending on your grade.
5A: FFX1MSBC
5B: TO1DZQ1J
5C: 65QLOXTG
5D: 1KOMQ6FQ

Are you in or out of the system?
Good Luck!!

Areas

Hello everyone; In this last part of the term we are going to work on areas (as I told you previously). I'm going to leave this video so that you can clarify any doubts you may have. Another resource you can use is the following website: www.thatquiz.org

Operations with fractions

Properties of quadrilaterals

Example: Divide 0.539 by 0.11

Hello everyone; check this example that will help you understand better. It is taken from www.mathisfun.com 

Move the decimal point so the divisor (0.11) is a whole number:

move 2 spaces
0.539		5.39		53.9
0.11		1.1		11
move 2 spaces

But what about 53.9? It still has a decimal point.

Well, we can ignore the decimal point in the dividend so long as we remember to put it back later. First we do the calculation without the decimal point:

049 11)539      0      53      44       99       99        0

Now put the decimal point in the answer directly above the decimal point in the dividend:

04.9 11)53.9

The answer is 4.9

Divide easily

This is the way you can do It.

Dividing Decimal Numbers

Hello everyone; Please check the following videos so that you can clarify this concept.

Multiply Decimals

Hello everyone; remember that when you have to multiply decimals you must follow these steps:

1. Count how many spaces there are after the decimal point in each number.
2. Locate the number which has the most digits on top 
3. Multiply as if the point didn't exist.
4. Locate the decimal point depending on how many spaces you had in each number. 

Example:

3.12 X 4.2

• The first number has 2 spaces 
• The second number has only one space
• There are 3 spaces in total 

The answer is 13.104

Remember that a point is different from a coma.

ORDERING AND COMPARING DECIMALS

Hello everyone; here are some videos you can check to clarify place value, base 10 and how to order and compare decimals.
