Look through the book and consider various ideas for your How to Explain Everything. List at least three strong ideas here and give three ideas you have about different ways to demonstrate your lesson.
Remember, I did How to Round Numbers. My examples included rounding up, rounding down, rounding using decimals and finally leaving one example for the audience to solve. Once given enough time, I gave the answer.

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
