ReplyDeleteIdea 1: Order of Operations

ReplyDelete- start with the parentheses

example: [9+8]

- multiply and divide from the left to the right

example: 2*10

- add and subtract from the left to the right

example: 7+9

Idea 2: Dividing compatible Numbers

- estimate the dividend

- start to divide the dividend

- put the the numbers on top of the dividend

Idea 3: Multiply the hundreds

- multiply in the ones place

- multiply in the tenths place

- multiply in the hundredths place

Idea 1 Rounding down

ReplyDeleteExample: 2734

Round the tens place. Look at the tens place (3). Now look to the right of it. This is the ones place. This number determines if you round up or down. In this case, we are rounding down because if the

number is 4 or below we round down. 4<5 so it goes down and changes to a zero. This makes your

new rounded number 2730.

Idea 2: Rounding up

Example:4365

Look at the hundreds place (3). Now look to the right of it. This is the tens place. This number determines if you're rounding the hundreds place up or down. In this case we are rounding up because if the number is 5 or above then you round up. 6>5 and 4 so we round up. You now change the 6 and the 5 to a 0. Our new rounded number is 4300.

Idea 3: Rounding decimals down

Example:67.34

Rounding decimals is almost the same thing as rounding whole numbers. Look at the ones place (7). Now look at the number to the right of it. This is the tenths place. This number determines if we are rounding up or down. In this case we are rounding down because 3<5. Now we change the 3 and4 to zeros. Our new rounded number is 67.00.

idea 1 multiplication

ReplyDeleteexample : use the box method

example : annex zeros to make problem easier

example : use the distributive property method

idea 2 division

example : annex zeros to make problem easier to solve

example : when estimating use compatible numbers to make the dividing easier

example : use multiplication to check answer

idea 3 adding decimals

example : to make sure to line up ones tens and hundreds

example :make sure to place the value dot on the right place of the addends

example : annex the zeros in the end

idea 1 rounding decimals up and down ex: 13.45

ReplyDeletestep 1) look to the right of the number if it is 5 or greater than 5 round up,ex:45 would round to 50 step 2) if the number to the right is less than 5 than you round down ex:13 would round to 10

step 3) if the number to the right is 0 than there is no reason to round ex: 30 would round to 30. your rounded number is 10.50.

idea 2 adding decimals ex: 14.3 + 2.30

step 1) look at the zeros and see if they are needed if not take them away ex:12.30=12.3 now it will make it easier to add.

step 2) add the tenths place ex: 3 + 3=6

step 3) add the wholes/ones place ex: 14 + 2=16

your added number is 16.6

idea 3 rounding the hundreds tens and thousands place ex: 5,256

step 1) look at the thousands place and the number to the right of it, the number is less than 5 so round down ex: 5,200 rounds to 5,000.

step 2) look at the hundreds place look at the number to the right of it the number is 5 so round up ex: 5,250 rounds to 5,300

step 3) look at the tens place and look at the number to the right of it the number is greater than 5 so round up ex: 5,256 rounds to 5,260

Idea 1: rounding

ReplyDeleteExample 28 Round to the tens place, look at the 8 round up because it is greater than 5 so 28 rounded to the tens place is 30

Example 43 round down because 3 is less than 5 so 43 rounded to the tens place is 40

Example 2.549 rounded to the tenths place is 2.500 because 4 is less than 5 so we round down and turn all the digits after the four into zeros

Idea 2: Converting fractions into decimals

Example ¼ is Equivalent to 0.25 because ¼ can be changed into 25/100 and that is equal to .25

Example 2/5 +3/5=5/5 and 5/5 is Equal to 100/100 witch can be converted to 1.00

Example 1 2/5 first you can convert 2/5 to 4/10 Equivalent to 0.4 then add 1 to get 1.4

Idea 3: Multiplication

Example 2x16 First you have to multiply the tens place 2x10=20 then multiply the ones place 2x6=12 then add them together 20+12=32 and 32=2x16

Example 12x34 first you multiply the tens place 10x30=300 then multiply the ones 2x4=8 then add them together and get 308=12x34

Example 123x456 first you multiply the hundreds place 100x400 to get 40,000

Then multiply the tens place 20x50 to get 1,000 then finally multiply the ones place 3x6 to get 18 then add them all together and get the final product 41,018=123x456

Idea 1. Mental Math for addition

ReplyDeleteExample: add digits numbers under ten

Example: add decimals that go up to the tenth's place

Example:add numbers above above 100 and below 1000

Idea 2: exponents

Example: do cubed and squared exponents

Example: do exponents with numbers 4 and under, and the exponents small like 3 to the power of 3

Example:do exponents with low numbers, but higher powers

Idea 3: division

Example: divide numbers under 10

Example: divide one -digit numbers with 3-digit numbers easy to work with

Example: divide 2-digit numbers by 3-digit numbers

Idea1: rounding

ReplyDeleteExample: rounding up in the thousands

Example: rounding down in the thousands

Example: rounding up in the hundred thousands

Idea2: multiplying

Example: multiply one digit by one digit

Example: multiply one digit by two digit

Example: multiply two digit by two digit

Idea3: dividing

Example: annex the zeros

Example: carrying the numbers

Example: remember the remainder
