If students have difficulty learning the math facts
by heart, working out the facts with a little finger math
might help. Students will usually master skip counting
by 2's, 5's and 10's but are error prone skip counting
for numbers other than 10 above 5.
The first screen
presents multiplying numbers above 5 by 3.
When you click on the hand, the fingers will be
extended, the finger count is shown above the hand.
Note the finger count is by 2's a number of times
equal the second factor of the statement. (the
extended thumb represents 5 to allow counting to 9
on one hand).
The product is tracked below the numerical
statement.
When the finger count by 2's is completed, the
hand is closed and the count is continued by 1's a
number of times equal the second factor again.
On completing the count again the student
arrives at the correct product.
To change the second factor click the Times (X)
button.
Click the first
factor to see the second screen which presents
multiplying numbers above 5 by 4.
Note the hand displays an extended thumb and 3
fingers to represent a count to 8, 5 + 3.
When you click the hand, fingers from right to
left will unextend to represent the numbers called
when counting after the second factor to 10.
The resulting count is then counted to by 5's
after another click closes the hand.
When the count by 5's is complete the count
continues by 1's until the extended fingers
represent 8 again.
On completing the 8 count the student arrives at
the correct product.
Click the first
factor to see the third screen which presents
multiplying numbers above 5 by other numbers above
5.
Now you will see a hand over each factor. The
little diamonds will help keep track of extended and
unextended fingers.
When you click a hand fingers are extended that
represent the count after the factor below the hand
to 10.
After you make these counts diamonds remain for
each unextended finger. Clicking each diamond counts
the tens of the product.
New diamonds appear below the extended fingers
of the right hand. Click each of these diamonds the
count of extended fingers of the left hand.
When all the diamonds disappear the student
arrives at the correct product.
