  • square root--------one of two equal factors of a number.
  • square number--------The product when a whole number is multiplied by itself.
multiplication patterns
Multiplication Patterns
  • One way to think of multiplication patterns is by using an array.
  • Remember that an array is an arrangement of numbers or symbols in columns or rows.
arrays
Arrays
  • 6 columns

X X X X X X

X X X X X X 2 rows

  • This array is a collection of 2 rows and 6 columns

How many rows does this array have?__________

How many columns does this array have?_______

How many X’s are in this array?_____

X X X X X

  • What multiplication problem can we make with this array?
  • Because we have 4 rows and 5 columns
  • We make the problem 4 x 5 = 20

Let’s practice

Area

What would the area if this shape be?

slide13

We will multiply 4 and 5.

The answer

will be written

in square units.

We are using

answer will be

slide18

If a shape is 3 by 3, then we can say that it has a

square number of 9. Because 3x3=9. We will write

the number under square root sign. It means the

square root of. If a problem asks for the square root

of 9 then we think of the

Problem 3x3. Our answer

will be 3.
