__Measuring Circles__

__Day #1 Exploring Circles__p. 155, 156 1,2__Reminders__**The main focus is get comfortable with circles and to examine the relationship between diameter and circumference****Radius is a straight line that attaches the middle point of the circle to the edge of the circle. It is half way across the circle****Diameter is a straight line that goes through the center of the circle. It is twice the radius.****Circumference is the distance around a circle.****Arc is a section of circumference at lies between the two ends of a chord.****Chord is a line segment that joins two points on the circumference of a circle**

__Day #2 Estimating and Calculating Circumference of a Circle__p. 158, 159 #6-17__Reminders__**Be sure to read carefully what the question is asking. If you are asked for an approximation or estimate use the formula for estimating. When you are asked to calculate or an exact answer, use the calculating formula.****Pi is a constant we use in math and is 3.14.****Formula for Estimating Circumference C=3xd (the equal sign should have a dot above it to indicate it is approximately equal to)****Formula for Calculating Circumference C=Pixd****If you are given radius to need to muliply it by 2 to find the diameter. d=rx2**

Reminders

__Day #3 Mid Chapter Review__p. 160,161 #1-7Reminders

**Don't forget to use approx. equal to and 3 when estimating.****Don't forget to use equal to and Pi when calculating**.

__Day #4 Estimating and Calculating Area of a Circle__p. 166, 167 #4-9__Reminders__

**Area is the amount of coverage in or on a shape.****Formula for Estimating Area of a Circle A is approximately equal to 3 x r squared****Formula for Calculating Area of a Circle A = Pi x r squared****When calculating area, our answer is always in square units**.

__Day #5 Working Backwards__p.170 #5-7, 10-12__Reminders__

- In order solve for the area of a circle when given the circumference, be sure to write out the formula for circumference
- Write in all the information you are given. Be sure to work backwards to solve for the missing letter.

__Day #6 Math Review__p.174,175 #1-10__Reminders__

- Don't forget to read the question carefully. Be sure to use the correct formula.
- Always write the formula to begin your solution to a problem.
- Radius is half the diameter or diameter divided by two. Diameter is double the radius or radius times two.

__Surface Area__

Reminders

__Day #1 Surface Area of a Cylinder__p.376 #4-9Reminders

**A cylinder is created by two circles and one rectangle****Formula A of Circle =Pi x r squared****A of Rectangle = length x width****To find the length you often have to calculate the circumference of the circle****C = Pi x d****Remember area has square units**

Reminders

__Day #2 Volume of a Cylinder__p. 380 #6-14Reminders

**Volume of Cylinder = Area of base x height****Volume of a Cube/Rectangle = length x width x height****Remember that volume has cubic un****its**

Reminders

__Day #3 Surface Area of 3D Shapes__p. 384 #4-7Reminders

- The surface area of a shape is all its sides or exposed faces
- Remember Formulas
- Area of Rectangle/Square A=length x width
- Area of Circle A= Pi x r squared
- Area of Triangle A= base x height /2
