Ten's

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.  

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

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.
