By fifth grade students are familiar with skip counting by 10's. It's relatively easy for them.
I think the point to make when building understanding of 10 as a factor is relating it back to 1. For example, 1 x 2 is 2 and 10 x 2 is 20. The connection between these facts is that we are moving into the tens place and the ones place becomes a zero.
Students need time to think about the connection between multiplying by 1 and multiplying by 10.
I have included a two short videos for multiplying by 10. These are meant to be more of a review and practice instead of a concept introduction.
Spinner Tool
Students are given one of the spinners to fill out as a reference tool. The tool will be primarily used during the current level of the multiplication program but should be kept as a reference going forward to higher levels.
Flashcards
There is a set of flashcards provided for the current level. Each set of flashcards include the facts with their turn-around facts. It is important that the students are comfortable with the commutative property of multiplication.

There are two timed tests associated with this new factor. The first timed test is designed to be a one minute test of 40 problems and includes only multiplication facts with the new factor. The second timed test is designed to be a two minute test of 60 problems and includes all multiplication facts learned in the leveled program thus far.
