We have started a new topic for Mathematics about Fractions.  
Today we talked about because we knew... 

1/2 of 10=5 we also knew...

1/2 of 30=15     1/2 of 6=3     1/2 of 12=6     1/2 of 18=9     


   1/2 of 20 = 10                      1/2 of 100 = 50
   1/2 of 40 = 20                      1/2 of 1 000 = 500
   1/2 of 80 = 40                      1/2 of 10 000 = 5 000
 1/2 of 160 = 80                      1/2 of 100 000 = 50 000
 1/2 of 320 = 160                    1/2 of 1 000 000 = 500 000...
 1/2 of 640 = 320
1/2 of 1 280 = 640
1/2 of 2 560 = 1 280...

1/4 of 10 = 2.5     1/2 of 10 = 5     3/4 of 10 = 7.5 so...

1/4 of 1 = 0.25     1/2 of 1 = 0.5     3/4 of 1 = 0.75
