Decimals are Great

Do you know what are decimals?  Decimals are not the points between numbers.  Decimals are the dots that separate whole numbers from parts of a number.  For example decimals can be like this: 3.20 or 7,937,445.998,376.  Decimals can be as long as you want.  To put in a more simple way decimals are just another way to write fractions.  You can keep adding numbers to decimals to make them an infinite number.

 

Decimals can come as fractions or in measurements or in money.  For example you can have $2.35 you can also have 2.35 cm,mm,km, or m.  Another example of decimals are 1 over 100 but to write that as decimals it would be 0.01.  The numbers before the point go in order backwards from the numbers after the point.  For example the numbers before the point go in order like this: tenTHS, hundredTHS, thousandTHS, and so on. the numbers after go like ones, tens, hundreds, thousands, and so on

 

This is how to write decimals, they are not points they separate numbers from whole numbers.  If you have a test with decimals on it, remember this stuff.  I have a task for you to do, ask you parents to make a decimal place value test tell me you score on the comments below.  I hope these things have made you understand what decimals really are, don’t forget this stuff.  Bye!

 

 

 

Prime Numbers

2,3,5,7,11,13.

What are these numbers?  They are called prime numbers.

What are prime numbers?  Prime numbers have exactly 2 factors.  A factor is a multiple of a number, for example: The factors of 25 are: 1&25, 5&5.

The number two has exactly 2 factors are:1&2

Prime numbers have to have only 2 factors 1 and itself.

The prime numbers up to 100 are: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,&97.

Trimester 1 Math Reflection

Hello readers today I want to tell you what I learned in math.

I learned about quadrilaterals example:

 

 

A line, line segment and a ray:

And graphs:

 

This all that I have learned in maths so far I hope you enjoyed!
