Try Lattice!http://

www.teachertube.com/members/viewVideo.php?video_id=86172&title=lattice_multiplicationFirst, you draw a rectangle. Write your

numbers across the top and down the right side.

Draw in boxes so that each digit has it’s own box, and then you draw in diagonal lines that cut each box in half.

Third, you multiply the digit on top with the digit on the right side. The ones place is placed under the diagonal line inside the box and the tens place is placed above the diagonal line.

Now once you have multiplied each digit, you just add down the diagonal stripes...  Start at the bottom and work your way up the stripes.

We get our answer by reading down the left side and across the bottom.  (Just ignore the first zero!)

Estimation Step Sheet Phrases that tell you to estimate: *Best estimate

*About*Approximately

How to round and estimate: 1st If you are doing an estimation problem, always round FIRST before you

perform any operation (addition, subtraction, multiplication or division)

2nd Ask: To what place am I rounding?

3rd Underline the number in that place.

4th Circle the number to the right of the underlined number: – the BOSS number*If the BOSS number is 0,1,2,3 or 4 it tells the underlined number to stay the same.*If the BOSS number is 5,6,7,8, or 9 it tells the underlined number to go up one.*Circling the boss number should remind you to turn it and all of the numbers after it to “0”.

5th Don’t forget to bring down all the numbers to the left of the underlined number.

6th Now you are ready to perform the operation.

7th Does your answer make sense? Is it one of the answers given? If it doesn’t make sense or isn’t an option in your test, go back and round to a different place.

We have two different songs that you can use:“Area goes length and height,Multiply to get the inside.Perimeter goes round and round,Add them up and write them down!”

“ Area, AreaThroughout the whole middle.For rectangles, it’s base x heightAnd your answer will always be right!Perimeter, PerimeterGoes around and aroundAdd up all the sides andThen write your answer down.”

One way to remember is Ladder Division.

Step 1: Read problem. This problem is read: “ 938 divided by 7.” (Think: How many 7’s in 938?)

938 ÷ 7 =

Step 2: Put problem in ‘house’ format. This problem is read: “7 divided into 938.” (We still think: How many 7’s in 938?)

7 938

Step 3: Think: 7 x _?_ = around 938? Think something easy like 1000, 100, or 10. Remember, your answer can’t be bigger than the number in the house.

CIRCLE THE NUMBER YOU MULTIPLIED!!

This is the most important step!!

7 x 100 =

-- 700

Step 4: Subtract your answer from 938.(938 – 700 = 238)

238

Step 5: Think: 7 x _?_ = around 238?

CIRCLE THE NUMBER YOU MULTIPLIED!!

7 x 20 =

-- 140

Step 6: Subtract, again.238 – 140 = 98

98Step 7: Think: 7 x _?_ = around 98?

CIRCLE THE NUMBER YOU MULTIPLIED!!

7 x 10 =

-- 70

Step 8: Subtract, again. 98-70 = 28

28Step 9: Think: 7 x _?_ = 28?

CIRCLE THE NUMBER YOU MULTIPLIED!!

7 x 4 =

-- 28

Step 10:

Subtract, again.28 – 28 = 0

0

Step 11:

Add all the numbers you CIRCLED. This is your answer!!

= 134

Note: Sometimes when you subtract at the end you don’t get zero. YOU ARE FINISHED WITH THE PROBLEM WHEN YOU SUBTRACT AND GET A NUMBER SMALLER THAN YOUR DIVISOR (in this problem, 7). Your leftovers are called ‘REMAINDERS.’

Another way to learn long division is (Dumb Monkeys Sit Backwards). Try to keep the steps simple, have the students write the multiples of the divisor, and use D.M.S.B (Dumb Monkeys Sit Backwards)

Dumb (Divide)Monkeys (Multiply)Sit (Subtract) Molly will show you how from a Backwards (Bring Down) teachertube.com video.

Create a Fact and Opinion Whale cut-out so that students can sort out facts and opinions.•Take a legal sized paper and turn it long ways•Fold it three times•On one end, cut off the two corners, giving the rounded shape of the whale’s head.•On the other end, cut a triangle in the middle of the very end, and then cut a triangle on the top and bottom towards the end with the triangle cut-out•Lastly, you open it up on the bottom two folds you write facts and opinions from the story you’re reading, and you color the front of your whale.•Any questions – Look at the examples on the table…

Draw a hand! Ask yourself – Who did what, when, where, and why? Use those details to pick out the big idea of the story and you have the details that support your main idea!

Ask about our little song…LOL!

It has the tune of “He’s got the Whole World in His Hands.”
