Math Monday

Brian has scores of 88, 95 on his first two math tests, he wants to have an average score at least 90 points.

There are total three tests, what score must Brian get on his third test to have an overall average of 90?

Hint:

Test 1:      88

Test 2:      95

Test 3:     ___

____________

270

Analysis: To achieve an average of 90 in three tests, Brian needs to

have total score 90+90+90=270, he already has two scores,

thus it is up to YOU to figure out what Brian must score in

test 3  to reach his goal?

Solution : 87.

Good Luck!

:) ;) ;)

Hello, how are you?

There are amazing secrets or magic in mathematical numbers such as 1, 11, 111, …., 111111111, 8, and 9,  etc.  The following is one of those.  Hope that math fans or those who are interested in math teaching and learning enjoy it.

———————————————————————————————
1 x 8 + 1 = 9

12 x 8 + 2 = 98

If YOU have a moment, please answer this simple question:

Take a piece of paper from your computer printer, 8.5*11 in size, you agree that there are four (4) corners for the paper which is rectangle shape, now take a scissor and cut one (1) corner off the paper by straight line (only once for each result), how many corners left on the remain paper?

Very easy if you actually do it!

Only a tiny trick in it, Good Luck!

Happy Saturday Evening!  ;) :)  ;)

PS: You can also fold it for one time to get a result, there are two solutions,

If you divide the rectangle into exactly two equal pieces of triangular paper, then you get 4-1=3, 3 corners,

But if you cut out one corner and get two pieces of paper, with a small triangle removed, you get 4-2=5 corners,amazing math humor, isn’t it?

Good job, everyone, everyone got 5 corners, the other case is a trick, as I mentioned…;) :) ;)

Magical number 9: https://jingleyanqiu.wordpress.com/2010/01/18/magical-numer-nine-9-on-math-monday/

Magical Number Nine (9) On Math Monday

Wow, It is Monday.  I decide to make Mondays Math Monday!

I miss Math, let’s discover the magic in number nine (9).

As you do “Times Table By 9” , you may notice that the digits always add up to “9”…

Let’s check it out:

1*9=9  –>0+9=9

2*9=18  –>1+8=9

3*9=27  –>2+7=9

4*9=36  –>3+6=9

5*9=45  –>4+5=9

6*9=54  –>5+4=9

7*9=63  –>6+3=9

8*9=72  –>7+2=9

9*9=81  –>8+1=9

10*9=90  –>9+0=9

Isn’t this number game FUN?

Does it work for larger numbers? You may wonder.

Yes, this works for any number multiples 9….

Say: 11*9=99  –>9+9=18  –>1+8=9

100*9=900  –>9+0+0=9

211*9=1899  –>1+8+9+9=27  –>2+7=9

1005*9=9045  –>9+0+4+5=18  –>1=8=9


42001*9=378,009  –>3+7+8+0+0+9=27  –>2+7=9

Amazing math facts! :).  I hope that YOU have FUN learning and discovering the magical number nine (9) on Math Monday.

If interested, please do an example to confirm this fact above:

___ *9=_____,  –>___+___=____,

Thank YOU for sharing the wisdom of magical numbers in nine (9).  Happy Math Monday to YOU All! :) :)

Happy Martin Luther King’s Day to You all Who Celebrate This Special Day!

Count From 1 To 10 Twenty different Ways (1-5)

Counting from 1 to 10 is very important to children’  initial learning about mathematical concepts. Recall on Barney And Friends of PBS , they count from 1 to 10 with two numbers connected at a time.  I revised the WORDINGS and share the first five (5) different ways of doing it, enjoy!

—————————————————————————————————————————————————

I:

1, 2, go to the zoo,

3, 4, shop at the store,

5, 6, build with bricks,

7, 8, sugar is sweet.

9, 10, buy me a pen.

II:

1, 2, Winnie the pooh,

3, 4, eat with a paw,

5, 6, search for beehives,

7, 8, honey tastes great,

9, 10, hungry again.

III:

1, 2, an owl says hoot,

3, 4, tigers roar,

5, 6, a fox hides in a box,

7, 8, a bird says tweet,

9, 10, stay in the den.

IV:

1, 2, cows say moo,

3, 4, two walls make a hall,

5, 6, chew the grass,

7, 8, breed in high rate,

9, 10, big fat hen.

V:

1, 2, ghosts say boo,

3, 4, stop the snore,

5, 6, do more tricks,

7, 8, juggle one more plate,

9, 10, birds love to sing.

————————————————————————————————————————————————–

Today’s Question for YOU:

How do you teach your kids to count? If you have no children yet, how did you learn about numbers when you were young? Do you enjoy counting at all?

Thank YOU for the time, Happy Monday!
