Concept
Concept wise, I have little to say about multiplying by 7. But, if students are progressing in leveled program I have created, there are only three facts that they have to master for the 7's, two of which are turn-around facts.
For this level students are left with 7 x 7, 7 x 12, and 12 x 7.
I have included two videos for the 7. The first one is a video of a cool trick with a tic-tac-toe board for 7's. The second one is of course from School House Rock.
Practice
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.
Games for Practice
Jumbo Tic-Tac-Toe
- Each player chooses one factor (2-12)
- Record the factor in the top of second column
- Toss 2 dice and find the sum
- Multiply the sum by the factor
- Record the product next to the sum in the table
- If the sum has already been filled, lose a turn
- First player to complete the table wins
Line It Up
- Toss 2 dice and find the sum
- Multiply the sum by 2
- Place a counter on the product
- If the product has a counter on it, lose a turn
- First player to build a full row or column wins
Face-Off
- Each player chooses one factor (2-12)
- Record the factor in the top of second column
- Toss 2 dice and find the sum
- Multiply the sum by the factor
- Record the product next to the sum in the table
- If the sum has already been filled, lose a turn
- First player to complete the table wins
Timed Test
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.
