Multiplication Strategies

By the end of this unit students will be able to:

**interpret products of whole numbers (That means students will be able to understand that 5 x 7 is the total number of objects in 5 groups of 7)

**use multiplication within 100 to solve word problems in situations involving equal groups, arrays, and measurements by using drawings and equations.

**use helper facts then adding a group or subtracting a group (distributive property) as strategies to multiply unknown facts.

** begin to build fluency all multiplication facts with products through 100.

** identify arithmetic patterns in the addition table, multiplication table, or number grid to help build fluency in multiplication.

**identify and represent fractions using pictures, words, and fraction circles and numbers.

**find the area of a rectangle with whole number side lengths by tiling it, and recognize that the area is the same as multiplying length times width.

Learning MULTIPLICATION Facts

We will be working very hard to come up with some good strategies to help us memorize multiplication facts.

For example:

To help us with our x2 facts (these are easy addition doubles)

To help us with our x3 facts, we learn to first double the other factor then add another set of that number.  For example 3 x 6... first double the 6 (6+6=12) then add another 6.

To help us with our x4 facts, we learn that we just need to double the double. For example 4 x 6... first double 6 (6+6=12) then double the 12 (12+12=24)

To help us with our x5, we learn to count quickly by 5's

(When using your fingers you can count by 5s then count by 1s)

To help us with our x9 facts we learn a cool finger trick or an even quicker way...we call it "Take One Off, Make it Nine"

9 x 2   (one less than 2 is 1 and 1+8=9 so the answer is 18)

9 x 3   (one less than 3 is 2,    2 and 7 make 9 so  the answer is 27)

9 x 4   (one less than 4 is 3,    3 and 6 make 9 so the answer is 36)

Cool eh?

We also have lots of cool multiplication rhymes to help us.

2x2=4

Two sets of twins on the floor.  2 times 2 equals 4

3x3=9

I’m free, I’m free and I feel fine.  3 times 3 equals 9

4x4=16

Floors, Floors they need cleaned. 4 times 4 is 16

5x5=25

Five bees in five hives, 5 x 5 is 25

6x6=36

Six dogs with six sticks.  6 x 6 is 36

7x7=49

Seven in Heaven feeling fine, 7 x 7 is 49

8x8=64

I ate and ate and got “sick” on the “floor”

9x9=81

Nine Nines having fun…9x9 is 81

6x7=42

6 and 7 stuck like glue, six times 7 is 42

6x8=48

Who do we appreciate?   6 times 8 is 48.

7x8=56

5,6,7,8…56 is 7 x 8
