Do you the students know their 2's facts? Well, if they do, 4's will be somewhat easy.
Multiplying by 4 is essentially doubling a double. For example, 4 x 3 is really like 3 + 3 and 3 + 3 or 3 x 2 and 3 x 2. What you're left with is 6 + 6 which is another double fact.
Although these simple relationships between factors are somewhat simple for educators to identify, students don't always make the connection and struggle with understanding.
I have included a short video for multiplying by 4. This is 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.
