Goal is to be able to name triangles based on their characteristics. The document shows the types of triangles and their names. There will be a thatquiz to practice naming triangles.

For this worksheet:
Watch video on Total Surface area of Triangular Prisms.
Use paper and pencil to record the area of each face and then add them together. Check your solution with the answer key.

This is a video to help you with a quiz on that quiz if you are having difficulty with comparing fractions.
We also talked about using benchmarks to compare fractions. Close to 0, less than 1/2, more than 1/2, close to one.
For example :
Compare 3/5 to 2/6. 3 is more than half of 5, so 3/5 is more than 1/2. 2 is less than 1/2 of 6, so 2/6 is less than 1/2.
Therefore we can say that 3/5 > 2/6.

Watch the video on finding the total surface area of a rectangular prism. You can think of this concept as how much wrapping paper it would take to completely cover the outside of a box.
Once you have watched the video you can try the activity on the left pane next to video. There will also be a thatquiz available to try. You should use paper and pencil to organize you calculations.

Goal is to practice estimating angle sizes.
You can use reference angles to help:
90 degrees use a corner of a piece of paper, 45 degress fold a corner of paper in half, 180 degrees straight edge of a piece of paper, a full rotation is 360 degrees.
The more you play the better you'll get. I challenge you to collect 50 bananas!!
This game requires FLASH.

I have created a few more quizzes on thatquiz for you to try. I'm planning to begin with finding Total Surface Area of rectangular prisms and triangular prisms later on this week. You should be comfortable with finding area of rectangles and triangles before starting Total surface area.
Example:
To find the area of a rectangle use the formula:
A = L X W (Area of Rectangle equals length muliplied by the width)
A = 3 mX 5m
A= 15 cm2 ( notice the units are squared)
For the area of a triangle use the formula:
A = bXh /2 ( Area of triangle equals the base X height divided by 2)
The base and height are always perpendicular( meet at right angles) to each other.

Once you have done the spyguys lesson you can try the thatquiz on Angles(Measurement).
All of the angles are multiples of 5 ( 5, 10, 15, 20, 25, etc.). So if you think the angle is 41 degrees, the correct measurement is 40 degrees.

On this website you can click on LESSONS and choose "Working With Angles". This may not work on Aplle products as it requires FLASH.
Goals for this lesson:
1. Understand angles and name the parts: vertex, rays, line segements, degrees
2. Classify angles as acute, obtuse, right, straight and reflex
You can look around the house for these different angles or use your arms to make and say the types of angles.
3. Measure angles using a protractor (on the computer)
There are two scales on the protractor. If you have an acute angle and you must choose between 140 degrees and 40 degrees. It must be 40 degrees because it is an acute angle.
