Multiplication Facts
 
Number Forms (word, expanded, standard)
 
Place Value- IXL 4th grade A.3.New
Tip: multiply by 10 (add a zero), multiply by 1/10 (take away a zero)
TRICK!!!! If they give you the answer, it's a Trick, Do the Opposite.
Example: 400 is 1/10 of what number?
                400= 1/10 x _______ [ the answer is given (400), so instead of taking away a zero because we see 1/10, it's a TRICK, so we do the opposite of take one away and add a zero. Therefore, the answer is:
                400= 1/10 x 4000
Value
To find the value of the underlined digit, simply write the underlined digit and turn everything else to a zero.
 
Standard Form- 126
Word Form- one hundred twenty-six
Expanded- 100 + 20 + 6
Expanded Extended- (1x100)+(2x10)+(6x1)
IXL- A.1, A.2, A.4, A.5
 
Exponents
The exponent tells the base how many times to multiply itself.
10 to the power of 5 = 10x10x10x10x10= 100,000    (a total of 5 zeros)
IXL- E.1, E.2, E.3, E.4

Chapter 2 "Times As Much"
 
 
 
Division Videos from Study Jams
 
 
 
 
Tip:
  • List your multiples first.
  • Underline the first digit of your dividend.
  • Place an "x" if your divisor does not go into your dividend. Or the number of times you can divide.
  • Make sure their is a number (or "x") above every number in your dividend.
 
Division Word Problems
  •  Total is your dividend
  •  If you see a number followed by the word "times" (Ex. 7 times as many) Draw your boxes to find the divisor. (p.138)
  • Make sure there is a WORD in your answer in a WORD problem
 

Interpret Remainder

 

NO REMAINDERS IN A WORD 

Full- quotient

Need- quotient + 1

Left- remainder

How many more- Divisor - remainder

 

Example: There are 74 students going on a field trip. Each bus can hold 30 students. 

Answer: 2 r 14

 

How many buses are full?__2__ (quotient)

How many buses do they need for all of the kids to be able to go on the field trip?__3_(quotient +1)

How many students are in the bus that is not full?__14_(remainder)

How many more students are need to fill the third bus? _16__ (divisor - remainder)

Comparing and Ordering Decimals

Stack ‘em- (Stack the numbers by lining up the decimals/add zeros)

Rank ‘em- (Place a number to indicate the order)

Write ‘em- (Write the numbers in order as asked in the question)

Comparing & Ordering Practice: IXL G.10, G.11

 

Adding & Subtracting Decimals

 

“LINE it up,                      (line up the decimals)

 DROP it down,             (drop the decimal straight down to the answer)

 ADD the zeros,            (add zeros to make equivalent)

 SOLVE!”                         (solve the problem)

 

 

Tip: Once the decimal has been dropped down to the answer, forget about it and treat the problem as if it were whole numbers.

Practice: IXL H.1, H.2, H.3, H.4

How to Divide Fractions: Keep, Change, Flip
1) Keep the first number/place whole number over 1
2)Change the division sign to multiplication
3) Flip the second number (ex. 3/4 would flip to be 4/3)
4) Multiply across

Averages: IXL- W.2, W.6, W.10
Tip: "average" is the same as "mean"
add all the numbers to find a sum, then divide by the number of "numbers that you added"
Example: 40 + 25 + 35 + 35 + 30=165      165 divided by 5 is 33. Therefore, the average is 33

Parallelograms have two sets of parallel lines,

Trapezoids only have one set at a time.

A rectangle has four right angles,

A Rhombus has four sides that are equal.

Squares have four equal sides and four right angles.

Quadrilaterals have four sides and four angles.

Parallelograms, rhombuses, trapezoids, squares, and rectangles.

And if you add the angles inside each of these,

there will be 360 degrees.
