Here are my rules. You may change th em or add to them,
or choose not to use some. I include an example on some
of them for the kids to have a visual when the are
working on problems. Remember to combine 2-4 of these
rules and pick a number for the kids to reach while
following your rules.
I gave examples for the number 32. (Don't forget to turn
on the overhead for kids to add great problems to while
they work. Let them know that they m ay write a question
mark ne xt to a problem that doesn't follow rules or has
an incorrect answer.)
Today's Number Rules: Example Numb er 32
You may not use any EVEN numb ers in your problems.
15 + 31 - 3 - 1 - 15 + 5 = 32
You may not use 5, 10, o r ZERO in your problems.
(3X7)+ 21-7-3= 32
You must use both addition and subtraction in your
problems.
35 - 15 + 12= 32
You must use mu ltiplication in your problems.
(5X5) - 12 + 10 + 9 =32
You must use DIVISION in each of your problems.
12 + (25 (divided by) 5) + 20 - 5 = 32
You may only use each number (not digit) once in each
problem:
This eliminates the possibility of ad ding a number and then subtracting it to
get back to zero.
You must use all 2-digit numbers in your problems.
86 - 12 + 11 - 53 = 32
You must use at least one 3-digit number in your
problems.
126 + 106 - 100 = 32
You must have at least five numbers in each of your
problems. 7 + 12 + 3 + 7 + 3= 32
You must include a fraction, de cimal, or percent in your
problems: (100 X .50) - (25% of 100) + 7 = 32
