Properties of MultiplicationIt is important to allow time for children to develop and understand the properties of multiplication. Simply telling students a mathematical rule rarely assures comprehension of the idea. Provide students with many opportunities to reinforce their understanding of these concepts. Materials: poster board; string and manipulatives such as counters or cubes for each student Preparation: Arrange students in pairs. Each pair should have 50 or more counters or cubes and twenty 12inch strings. Construct on poster paper an example of each of the properties. Post them on a bulletin board. An example of each is shown below. Commutative Property of Multiplication: Construct 3 groups of 4 and 4 groups of 3.




Identity Property of Multiplication: Construct 5 groups of 1 and 1 group of 5. 



Property of Zero for Multiplication: Construct 3 groups with 0 objects in each group.
You can talk to your students about 0 x 3 = 0 which is 0, or no groups with 3 in each group. If you have 0 groups, then there would be nothing to count.
WrapUp and Assessment Hints You can assess student progress by having students explain and justify their answers. For example:
