Here is a worksheet I am developing for Grade 3.  In this grade students
learn about multiplication and division.  It is done using many concrete
examples.

 

Finding the values of a collection of coins can help to introduce
multiplication.

 

Enter this dialog in a jqt terminal.  To insure that you do not always get
the same sequence as you run it several times, enter ?13 or any different
random number before beginning the first run of the code.  If you answer yes
and print a page, you could fold over the answer and then have the student
write their name and answer before looking at the correct answer.

 

NB. Piggy Bank
