Place Value 1 - 1
The first lesson is place value, that means putting commas in the numbers that need it.
The comas are added to a number for remarking a digit. The commas are putted in groups like the : Ones period that has none coma, the thousands period were you put the coma at the right of the fourth digit, the millions period were the coma is added right of the seventh digit, and the millions period were the coma is right of the tenth digit.
Don’t forget!
The only thing you can’t forget is that from the ones to the infinite, the numbers are going from left to right.
Comparing and Ordering Whole Numbers
Here you need to order the numbers to least to graters
Like this:
2 16 73 107 259
As you see the 2 is at the first and the 259 is as last,but in some case it will say you to put the greater number at first and the least number at last
Comparing numbers
here you need to determine if the numbers are greater than or less than or equal
Here the 67 is greater than 25 and 25 is less than 67
Here 34 is equal to 34
25<67
34=34

Decimal place value
Decimal place value
The names of the decimal values are really similar to the normal place value names but these are less than one.
Tenths, hundredths, thousandths, ten-thousandths, and beyond.
As you see you change the “d” for “th” and there no oneths because one is a whole number and it has no “d”.
Don’t forget!
The decimal point goes at the right of the ones and the tenths, etc. start(they go always right and they have less value). “Ten” has no “d” but in decimal it has.
1-4
Comparing and ordering decimals
Comparing and ordering decimals
Here is comparing what number is grater of the examples that they are giving to us, but is with decimals, but there a tricky thing about this is that if you see 1.20_1.2 the 1.20 is not greater than 1.2 because are exactly equal because if you put one zero to the 1.2 it convert into 1.20
Example:
1.86>1.29. 2.34=2.340 1.59<10.5631
Don’t forget!
The zeros at the right of a decimal have no value.
