In our multiplication unit we have been playing games to help us learn the properties of multiplication.
Order Property of Multiplication Game
A few weeks ago, Mrs.
Yollis made two
yellow factor cards, and she picked two people to be "factors". The "factors" chose a number from her box of digits.

Next, they hid their number under their yellow factor card.

When Mrs.
Yollis yelled, "Name the
product!" the two factors
revealed the factors to the class.

The class wrote down the multiplication sentence with the correct product.

Students with the correct product could then be chosen to be part of the game.

We learned that if you switch the order of the factors, the product stays the same.
8 x 9 = 9 x 8
Grouping Property of Multiplication Game
Today, we learned to multiply three factors! Mrs. Yollis made another yellow factor card and a set of cardboard parentheses. We learned a new game for this property.

Three students were chosen to be the "factors". They hid a number under their factor card. One at a time the numbers were shown. When all three factors were revealed, Mrs. Yollis allowed one person to be the
grouper. (An organizer, not
the fish!)

That grouper came up and grouped two of the factors with the parentheses. The class wrote the newly grouped factors in a number sentence on their white boards and solved the equation.

Students with the correct product could become a new "factor" or the grouper.
We learned that it doesn't matter how you group the factors.
(1 x 2) x 5 = 1 x (2 x 5) 
The product will always be the same.
We also learned that grouping certain factors together made it easier to come up with the product.
Perhaps you would like to play the games too!
