Nov. 17 Notes Parallel and Perpendicular

Parallel and Perpendicular Line Segments


Line segments - a line with a beginning and an end. A piece of a line. You know a line ends when it has dots at each end.
Line segments are labeled with letters.

Intersecting - lines that cross or meet.


Parallel - describes lines in the same plane that never cross, or intersect
- they are marked using "arrows"


Perpendicular
- describes lines that intersect at right angles (90 degrees)
- they are marked using a small square

Homework for Oct. 21 2010

Go over the quiz with your parents.

Estimating Quiz

1. _______________ is to approximate an answer.

2. _______________ is an estimate that is larger than the actual answer.

3. _______________ is an estimate that is smaller than the actual answer.

4. Use front end estimation to place the decimal in the correct place. Show your thinking.
2.63 + 9.05 + 7.92 = 196

5. Use relative size estimation to place the decimal in the correct place. Show your thinking.
857.643 – 349.832 = 5078110


HW - in your homework book do pages 14 – 17.

Notes and Homework from Oct. 19 and 20th

Adding and Subtracting Decimal numbers
Estimate - to approximate an answer.
Over estimate - estimate that is larger than the actual number
Under estimate - estimate that is smaller than the actual number

Front End Estimation: that is using only the highest place value when estimating. eg. 125 + 476 = turns into 100 + 400 =
It is like under estimating.

Relative Size Estimation: rounding to the nearest highest place value.
eg. 125 + 476 = turns into 100 + 500 =
125 is between 100 and 200 but closer to 100
476 is between 400 and 500 but closer to 500
It is like rounding.

Estimating - getting an approximate answer.
Calculating - getting an exact answer.
