Calendar Math

Copy this months calendar for each student and pass it out.

Ask students to look for patterns.

Someone usually notices that  the number underneath is  +7.

On the November page  the 8 is under the 1  The 10 is under the 3.so we can say

1 + 7 = 8    2 + 7 = 9   3 + 7 = 10

Ask a few questions:  Using the calendar what is  8 + 7, 14 + 7

 

Outline any 2 x 2 square        example       1       2

                                                                       8       9

Now  look at the diagonals .    1 + 9 = 10  and 2 + 8 = 10

Choose another 2 x 2  square

6          7

13      14

 

 6 + 14 = 20  so 7 + 13 = ?

Have students recite or record 2 other diagonals that are equal.

14 + 20 = 34  so 13 + 21 must equal 24

 

Out line a 3x3 square  for example:

  1     2      3

  8     9     10

 15  16    17

 

The middle number is 9  .   Double it     9 + 9 = 18

What is   1 + 17 ,   3 + 15,    2 +1 6,  8  + 10   ?

 

Outline another square and list  4 addition facts that are equal.

 

The Year of the Tiger  began  February 14 2010

 

Thirty days hath September, April , June and November.

 These months can be used for teaching equivalent fractions.

For example , I'm writing this on November 18 2010.

What fraction of the month will be over at the end of the day? 

18/30 or 9/15 or 3/5

What fraction of the month is left?
