Properties of Addition and Subtraction through Operations Puzzles Tip
Look at the numbers
While solving operations puzzles, students will find that 2+3 and 3+2 have the same sum, and 4+5=9 and where the columns
9-5=4 are related facts. Thus, students will use the commutative property and inverse operations (addition and and rows meet.
subtraction). An effective strategy in teaching students who are not yet familiar with operations is to precede
the explanation of properties with the use of puzzles. -

While solving the puzzle, have students observe the result of an addition problem when
the numbers are in different order such as 3 + 4 or 4 + 3. They also learn that the sum can
be found by using the difference. The greatest method for teaching these concepts is to
allow the students enough time to figure it out by themselves.
