Homework Review
Mental Math
Please take out your Fact Triangles.
Yesterday, you sorted them into two piles: OK and TRY
AGAIN.
Spend the next two minutes practicing your facts in the
TRY AGAIN pile.
When you are finished, fasten the pile with paper clips
and store them until our next practice session.
Math Message
Take a look at the Properties of Polygons worksheet.
Let’s look at the example together.
Complete the rest of the page independently.
Types of lines
What differences do you notice between
these sets of lines?
Lets look up the term parallel in our
Student Reference Books.
Parallel Lines
lines on a flat surface that never
meet or cross; they do not intersect
Based on the definition, which one is parallel?
Parallel Line SegmentParts of lines that are parallel. They do not intersect no
matter how far they are extended.
Parallel RaysTwo rays that are part of a parallel line; they do not intersect
and will never intersect no matter how far they are extended.
What are the similarities and
differences?
How do we classify?
• Quadrangles- 4-sided polygons
• How can we classify them?
– Number of sides
– Number and type of angles
– Length of sides
– How many parallel pairs of sides
Cut out the shapes from the Quadrangles
worksheet.
Work with a partner to list the qualities of each
shape. Write down your answers in your notes.
For each shape make sure you have listed:
-Number and type of angles
– Length of sides
– How many parallel pairs of sides
How are quadrangles similar and different to other
shapes?
Closure
On your slate, list 3 examples of parallelograms.
Choose on of the parallelograms and list its
qualities.
Number of sides
Number and type of angles
Length of sides
How many parallel pairs of sides
Share with your table.
