Math Family Night C-FB ISD Grades 3-5 2012-2013

ONE FACTS ZERO FACTS

The product of any number (factor) and 0 is 0.

The product of any number (factor) and 1 is the original factor.

ONE FACTS ZERO FACTSDOUBLE

The product of any number (factor) and 2 is just double the original factor.

How will this help your child in the future? Try these: 15 x 2 = 1.2 x 2 = 134 x 2 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE

The product of any number (factor) and 4 is just double, double the original factor.

How will this help your child in the future? Try these: 15 x 4 = 1.5 x 4 = 124 x 4 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE DOUBLE

The product of any number (factor) times 8 is just double, double, double the original number.

How will this help your child in the future? Try these: 22 x 8 = 2.1 x 8 = 1/2 x 8 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE TENS Place Value Shift DOUBLE, DOUBLE DOUBLE

The product of any number (factor) and 10 is 10 times as large. (Any number times 10 causes the number(factor) to shift to the left one place value.)

How will this help your child in the future? Try these: 15 x 10 = 1.2 x 10 = 134 x 10 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE TENS 5 IS HALF OF 10 DOUBLE, DOUBLE DOUBLE

The product of any number(factor) and 5 is just the product of the number times 10 and then half the product.

How will this help your child in the future? Try these: 15 x 5 = 1.2 x 5 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE TENS Place Value Shift Tens Minus 1 Group DOUBLE, DOUBLE DOUBLE 5 IS HALF OF 10

The product of any number and 9 is just the original number times 10 minus the original number.

How will this help your child in the future? Try these: 15 x 9 = 134 x 9 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE, DOUBLE TENS Place Value Shift Tens Minus 1 group DOUBLE, DOUBLE DOUBLE 5 IS HALF OF 10 DOUBLE + ONE

The product of any number (factor) and 3 is just the original number doubled plus the original number.

How will this help your child in the future? Try these: 15 x 3 = 1.2 x 3 = 7/8 x 3 =

ONE FACTS ZERO FACTSDOUBLE DOUBLE + ONE DOUBLE, DOUBLE TENS NINES 5 IS HALF OF 10 5 AND ONE MORE DOUBLE, DOUBLE DOUBLE

The product of any number (factor) and 6 can be thought about in two ways. 1 group more than 5 times a number or the number times 3, doubled.

The product of any number (factor) and 6 is the same as the number times 5 plus the original number.

ONE FACTS ZERO FACTSDOUBLE DOUBLE + ONE DOUBLE, DOUBLE TENS NINES 5 IS HALF OF 10 5 AND ONE MORE DOUBLE, DOUBLE DOUBLE

To find the product of any number and 7, think about using the commutative property and then apply that strategy.

Let’s all work together to ensure our students know their multiplication combinations with automaticity, but through strategy.
