TimesTables Cool Trick

The magic 9 times table trick with fingers:

The fingers on the left hand represent the numbers 1 through 5. The fingers on the right hand represent the numbers 6 through 10.

-Fold down the index finger on left hand, or finger number 4.

-Remind her that 9 x 4 = 36, and then have her look at her hands. To the left of her bent finger, there are 3 fingers. To the right are her remaining 6 fingers.

-The magic to this trick is that the number given to the finger that she folds down x 9 is equal to the number of fingers to the left of the bent finger (in the tens place) and the fingers to the right (in the one's place.) It is MAGIC!!!

Common Core:

Common core times tables / multiplication works with the “box method”. For example, multiplying 7 x 23. First you divide a large number into its separate parts, 23 becomes 2 and 3. Next you multiply each separate part 20 x 7 and 3 x 7. Finally, you at all products together 140 + 21 = 161.  The product of 7x23=161.

The Common Core State Standards introduce multiplication over three grades (3, 4, and 5) with the standard algorithm as the culminating activity in grade 5. To meet these common core multiplication standards, students need to “know from memory all products of two one-digit numbers,” by the end of Grade 3.
