Mrs. Brown has put stickers in her sticker book. The book has 3 rows with 7 stickers in each row. How many stickers does Mrs. Brown have? Draw the array and solve
3 x 7 = 21
3 x _ = 21
7 x _ = 21
3 x 7 = 21
7 x 3 = 21
Five groups of 5 equals to...
5+5+5+5+5=25
3 x ? = 15
3 x 5 = 15
If I add 5+7+6+4 is that repeated addition?
No!
What is the multiplication sentence for Mrs. Brown's array?
4 x 4 = 16
How are Mrs. Brown's arrays the same? How are they different?
Let's discuss!
Six groups of two equals to...
2+2+2+2+2+2=12
? x 6 = 24
4 x 6 = 24
Solve using repeated addition:
4 x 6=?
6+6+6+6=24
Draw the array to solve for:
6 x 3= ?
Class, are they correct?
6 x 3=18
6 x 8 = ?
8 x 6 = ?
48
7 groups of 4 equals
4+4+4+4+4+4+4=28
3 x ? = 27
3 x 9 = 27
Solve using repeated addition:
5x9=?
9+9+9+9+9=45
Draw an array to solve for:
8 x 7 = ?
I will check your array!
8 x 7 = 56
Solve:
9x_=45
Then write the commutative multiplication equation.
9x5=45
5x9=45
