The document discusses place value and how numbers can be decomposed into their individual digit places of hundreds thousands, tens thousands, thousands, hundreds, tens and ones. An example shows 854,369 decomposed as 8 hundreds thousands, 5 tens thousands, 4 thousands, 3 hundreds, 6 tens and 9 ones. The document also covers comparing numbers based on their place values from left to right and using symbols to show greater than or less than relationships.

2. A SIX DIGIT NUMBER CAN BE DECOMPOSED IN HUNDRED
THOUSANDS, TEN THOUSANDS, THOUSANDS, HUNDREDS,
TENS AND ONES.
The number 854,369 can be read as eight hundred fifty four
thousand three hundred sixty nine and can be decomposed as:
854,369: 8HT + 5TT + 4T + 3H + 6T + 9O
The number 854,369 can be decomposed according to the place
value in an expanded form:
854,369: 800,000 + 50,000 + 4,000 + 300 + 60 + 9

3. When you compare two numbers, is bigger the one that has more
digits.
How do we compare two numbers that have the same amount of digits?
Example:
We compare the digits in the same place value from left to right until
we find a different one.
Is smaller the number that has the smallest digit. Then you use the
symbol between the numbers.

4. An addition is an operation that allows us to put together two or more
quantities.
ANDREA
Example:
DIEGO
II have $94,850
for my mother´s
gift.
How much money do
we haveIn total ?
II have $120,500.
Let´s put the money
together and buy a
nice present for our
mother.

5. In order to find the total we do an addition. We organize the
quantities one below the other making sure that the numbers
are organized according to the place value.
120,500
+ 94,850
Andrea´s money
Diego´s money
21 5, 3 5 0
We start adding by the one´s place and if we need we regroup.
Andrea and Diego have $215,350 in total for their mother´s gift.

6. A subtraction is an operation that allows us to find the difference
between two quantities.
Example:
Mr Pepperoni
The price of a
slice of pizza
is $ 2,800.
Pablo
If I pay you
with $20,000
how much do I
receive left?

7. We do a subtraction in order to find the money left. Remember
to start subtracting the number in the one´s place. If needed you
have to regroup.
1 9 10
20,000
- 2,800
17,200
Pablo has $17,200 left.
Bill
Value of 1 slice of pizza
