Teachers, save “Math Lesson #6: I can identify the tens…” to assign it to your class.

There are a total of 4 pages. For the first slide you will count and write the total. For the second slide you will count and add 10 more. For the third slide you will take away 10. For the last slide you will record your voice explaining what happens to the ones when you add 10 more or 10 less.
