### 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.

HW Textbook pg. 48 - 51 # 4 - 25 even numbers
