The identity property of addition is a rule or law of basic math operations. In this video, the teacher explains that the identity property of addition means that when adding zero to any number, the number will not change. Examples are given on the whiteboard and the teacher emphasizes that zero means nothing, therefore the answer will be the other number in the problem. Adding zero to a number does not increase the total.
When doing the worksheet, the teacher directs the students to look at several different number sentences and circle the sentences that show the identity property of addition. The teacher carefully explains each one by saying that if you add any number other than zero to another number, then this increases the total and this does not show the identity property.
Increase your students’ number sense and practice identifying the identity property of addition with this worksheet and instructional video.
