SQUARE ROOT

To understand today's scribe, we have to know what is a square root before anything else.
A square root is the opposite of squaring. So, instead to pressing the squared sign on the calculator, we press square root button.


HOW TO FIND A SQUARE ROOT

1) Get a calculator with square root function.

2) Since all calculators are different, try to press buttons until you get the answer. Maybe put number first, then the square root button or hit the square root button first then,the number. It all depends on how your calculator works.

3) Press the equal sign and "boom!" a bunch of numbers are on your calculators. You can round it to the hundredths though. Its easier to look at. It might not be the exact but, its close enough.


* ALL numbers have square roots. Its just that majority of them ends up with decimals.


EXAMPLE: Get the square root of 5.

1) On a calculator press √ then 5 or the opposite way.

2)Hit the equal sign button.

3)Once the answer appeared, round it to hundredths .
√3=2.23²


HOW TO ESTIMATE A SQUARE ROOT

To estimate a square root you may loo at the square root chart we made. Let's say we need to estimate what the square root 0f 570. We look at the chart and find what is closest products to 570. They are 576 and 529. Since 567 is closer, we choose that. 567's factors are 24x24, so that is an idea that the answer falls near 24.

EXAMPLE: Estimate the square root of 243.
243 falls between 225 and 256.Which is the product of 15X15(225) and 16X16(256.)Since, 256 is closer we
choose that. Now all we have to do is estimate what is the decimal needed.


ESTIMATING SQUARE ROOTS BY FRACTION

In this part, the number line we made would be helpful to us in this section.



Since there is 3 spaces between the first square root and the second square root. We would use 3 as our denominator.

1) 1/1 or 1

2)1 1/3 because, its in the first place after the perfect squared number.

3) 1 2/3 because, its in the second place after the perfect squared number.

4) 1 3/3 or 2 because, the square root of 4 is 2.

*Take note that we always don't use 3 as the denominator. It depends on how many spaces are there between a perfect squared number to another.


HOMEWORK

Use fractions to estimate the square roots of 1-25.

How can you use perfect squared numbers to estimate square roots?

Still having trouble? No problem!I provided links and video to help you understand more!:)

RATIO:

Two Term Ratio-it compares 2 quantities measured in the same unit

EXAMPLE: monkey: horse: winter toys

2 :1:2

Three Term Ratio- compares 3 quantities measured in the same unit.

EXAMPLE: monkey: horse: winter toys

2 :1:2

Part to Whole Ratio- compares different parts of a group to each other. It can

be written as fraction, decimal, and percent.

EXAMPLE: horse: all stuff toys
1:5

Part to Part Ratio- compares different parts of the group to the whole group.

EXAMPLE: horse : monkeys
1 : 2

RATE:

Unit Rate- a rate in which the second term is one.

EXAMPLE: $3/ per 6 pieces of white stones

Unit Price- a unit used when shopping.

EXAMPLE: $/ gram, $/ kilogram,

$/ hour, kg/ hour, etc.

PROPORTIONAL REASONING:

PROPORTION:a relationship that say 2 ratios or 2 rates are equal. Can be written as fraction.

EXAMPLE : ( $ / cookie) ( $ 4.50 / 10 cookies) = ( $ 11. 25 / 25 cookies)

Kaecee's Perfect Squares Scribe Post

1², 2², 3² are Perfect Squares.

HOMEWORK: 

Tell me everything you know about the squares:

[1] [2] [3] [4] [5] [6] [7] [8] [9] 

You will need to blog about it! 

Ohyea, and here's a video to help you find the Square Root :)

Square Numbers & Square Roots

Focus on...

[  ] determine the square of a whole number.

[  ] determine the square root of a perfect square.

A square number is the product of the same 2 numbers.

ex. 3x3= 9 so, 9 is the square number.

Here is a video on how to find a square number.

& here is a game you can play to help you on square numbers/roots!

Continue your Perfect Square Chart all the way until 30! It will be for homework! 

Also, your other piece of homework is the long white, blank sheet.

If you forgot what to do on that sheet here are instructions:

- On the lines mark 1 and a half CM, 25 times.

- Since there are only 25 marks, you will only get to 5x5=

So on your sheet, you will be marking:

1, 2, 9, 16, and 25. Because it is the answers to 1x1 - 5x5.

I'm sorry if it sounded confusing, I tried my best to explain it!

Don't forget to comment and do the homework! :)

Ratio:
two-term:Compares two quantities in the same units.(red shoes to blue shoes,5:7)
three-term:Compare three quantities in the same units.(red shoes to blue shoes to black shoes,5:7:8)
part-to-part:Compares different parts of the group to each other.(red hat to white hat,2:3)
part-to-whole:Compares one part of the group to the whole part of the group. It can be written as fraction,decimal and a percent. ( red hat to all hats. 2:10)

Rate:Compares2 quantities measured in different units.
unit rate: A rate where the second rate is one. (10 letters/1 minute)
unit price:Used when shopping.($0.95/2ml)

Proportional Reasoning: A relationship that say 2 rates or ratios are equal. It can written in fraction form. 3/9 = 9/27 x3
