ADDITION

These strategies are useful for helping your child develop fluency with basic addition:

Count All : Count all of the objects in both numbers (This is just for the beginning to establish the concept of addition)
Count On : Start with the bigger number and count on (This is a transitional strategy to get us out of the counting all)
Add 2 : Start with the bigger number and skip a number to add by 2 (5+2 skips over 6 and finishes at 7 on a number line)
Add 3 : Use your 'Add 2' strategy and go 1 further (Once you know 5+2=7, go 1 more for 5+3 and get 8)
Add 4 : Use your 'Add 2' strategy twice (If you know 5+2=7, do another skip by jumping over 8 to solve 5+4=9)
Doubles : Adding a number with itself (This is quicker and easier than just counting on, and is used heavily for multiplying)
Doubles plus One : Use your doubles facts and add 1 extra (In 4+5 think of 5 as 4+1, so 4+5 is 4 doubled  plus 1)
Turn-Arounds : You can switch the addends (Used best when adding 5,6,7,8; If you know 8+2, then you know 2+8)
Add 9 : Start by adding 10, then just take 1 away (For 8+9 start with 8+10  and take away 1 to get 17)
Add 10 : To add 10 you are putting 1 in the tens column (7+10 starts with 0 tens,7 ones; We put 1 in the tens column )
Make 10 : Create a group of 10, then add on (For 8+6, think of 6 as 2+4, so 8+6 is 8+2+4 which is just 10 and 4 more, 14)

Note: These strategies are adapted from the work of mathematician/author Greg Tang.

EVERYDAY MATHEMATICS ANIMATIONS OF ADDITION STRATEGIES SUBTRACTION These strategies are useful for helping your child develop fluency with subtraction:

Subtract to 10 : Subtract to get back to 10, then subtract the rest (12-5 : 12-2 gets you back to 10 then -3 = 7)
Subtract to 10s : Subtract to get back to the nearest ten, then the rest (82-5 : 82-2 gets you 80 then -3=77)
Subtract to 100 : Subtract to get back to 100, then subtract the rest (120-50 : 120-20 get you to 100, then -30 = 70)
Add Up : Use addition to find the difference between numbers (17-8 : 8 +2 makes 10 then +7 more for a total of 9 [2+7] )
Parital Differences : Find individual column differences (48-36 : Tens [4-3=1] Ones [8-6=2], so answer=12)

MULTIPLICATION These strategies are useful for helping your child develop fluency with basic multiplication:

x 0 : The answer will always be 0
x 1 : The answer is the same as the number being multiplied by 1
x 2 : Just double the number that is being multiplied by 2 (The groundwork here was established in addition)
x 3 : Doubles plus one (5x3 = 5x2 plus 5x1. This is 5 doubled  plus one more group of 5 )
x 4 : Double Double (5x4 = 5x2x2. This is 5 doubled  and then double that answer to get 20)
x 5 : Multiply by 10 and then cut it in half (6x5 = Start with 6x10  and then just cut in half to get 30)
x 6 : Multiply by 3 and then just double (8x6 = Use your previous knowledge [8x3=24] and double the 24 to get 48)
x 7 : Multiply by 5, Multiply by 2 and combine (8x7 = 8x5  plus 8x2  ; The final answer is 40+16, or 56)
x 8 : Multiply by 4 and then just double (9x8 = 9x4x2. This is 9x4 doubled : 30 doubled=60 + 6 doubled=12, total is 72)
x 9 : Multiply by 10 then take away a group (9x3= 10x3  take away a group of 3 [30-3] to get 27)
x10: Just tack on a 0 at the end (8x10 = 8 groups of 10, or just 8 in the tens place followed by a 0, which is 80)
x11: For single digits it's just a repeat (9x11=9x1 in the tens column  plus 9x1 in the ones column or 9 shown twice  )
x12: Multiply by 10, Multiply by 2 and combine (7x12 = 7x10  plus 7x2  for a total of 84 when you add the 70 and 14)

DIVISION These strategies are useful for helping your child develop fluency with basic division:

÷ 2 : Just split the number in half (18 ÷ 2 is just 18 cut in half, which is 9)
÷ 4 : Cut in half twice (24÷ 2 is just 24 cut in half  then cut that in half to get 6)
÷ 5 : Double then divide by 10 (30÷ 5 is done by doubling the 30  & dividing by 10,which removes the 0 ones  )
÷ 6 : Cut in half, then divide by 3 (42÷6 is 42 cut in half  then divide that by 3 to get 7 )

÷ 8 : Cut in half three times (48 ÷ 6 is 48 cut in half  which gets cut in half  and one more time  )
÷10 : Remove the 0 that is in the ones column (90÷10 is done by deleting the 0 in 90 to get 9)

Note: These strategies are adapted from the work of mathematician/author Greg Tang.
