Warm Up Find the GCF of 108 and 244. Find the LCM for 150 and 120. *Shortcut method...

A perfect square is... Examples: *Connection: The operation of "squaring" a number means finding it's perfect square. It is called perfect because...

Record all perfect squares on grid paper to keep in your notes.

Finish modelling the remainder of the perfect squares from 1 to 100 in groups of 2 to 3. All members need to record the perfect squares on their own grid paper.

Color the perfect squares from 1 to 100 on your multiplication chart. -Be sure to use a different color than the one used for prime numbers last class. *If time permits, continue coloring the perfect squares from 1 to 400.

A perfect cube is... Examples: *Connection: The operation of "cubing" a number means finding it's perfect cube.

*Use the linking cubes to help you!

Model the remaining perfect cubes in groups. Record the perfect cubes in list form and by coloring all perfect cubes a third color on your multiplication chart.

Check your understanding:

A square root is the opposite of a square.

? 

Class Practice: Find the square root of the following numbers:

It is also possible to estimate square roots that are not perfect. Example: Estimate the square root of 63. Estimate the square root of 30. *NOTE: These squares are NOT perfect.

We can also find the square root of bigger numbers by using prime factorization: Example: Find the square root of 196. Step 1: Prime Factorization Step 2: Divide the prime factors evenly into two groups. Step 3: Multiply the factors to determine the square root.

 ? 

A cube root is the opposite of a cube. *The same process for square roots applies to cube roots but factors must be divided evenly into three groups.

Cube Root Practice: Find the cube root of the following numbers:

 ?   ? 

? ? Notice:

 ? 

Warm Up - Who Has?

Refresher: -Last class we focused on perfect squares and cubes. The square roots and cube roots we see may not always be perfect. Consider: Square root of 33 Cube root of 9 What do we know?
