### Lesson Objective

List a set of integers (both positive and negative), positive fractions (denominators can be greater than 10), mixed numbers, decimals, and percents in order from least to greatest and greatest to least both when the set is comprised of only one type of number and when the set includes more than one type of number Recognize that with respect to time, fastest means taking the least amount of time Translate among fractions, improper fractions, mixed numbers, decimals and percents Use information from a table to create fractions and ratios and to calculate percentages

### Lesson Plan

Teachers: Suba, Siesfeld

Subject:  Applied Math

Unit:    Measurement

BPCPS Standard(s)

8AM.NS.01 Compare Numbers

Students will be able to
compare, order, estimate, and translate among integers, fractions and mixed
numbers (i.e. rational numbers), decimals, and percents.

Objective(s)

SWBAT list a set of integers (both
positive and negative), positive fractions (denominators can be greater than
10), mixed numbers, decimals, and percents in order from least to greatest
and greatest to least both when the set is comprised of only one type of
number and when the set includes more than one type of number

SWBAT recognize that with respect to
time, fastest means taking the least amount of time

SWBAT translate among fractions,
improper fractions, mixed numbers, decimals and percents

SWBAT use information from
a table to create fractions and ratios and to calculate percentages

Today we will continue our number sense unit. This is the
second lesson on comparing and ordering, and we will also be identifying
numbers as fractions, decimals, and percents, and converting between them. We
have to be really sharp on our conversion facts. We will not have a mental

Answer #1 yourself. Solicit some hands on #2: share data

You cannot redo this one, but there will be another exit
ticket at the end of class today.

Open:
review—decimals to percents, percents to decimals

•   Decimals to percentsà
hop decimal twice to the right

-
6.5. Change to a percent

-
150. Change to a percent.

•   Percents to decimalsà
hop decimal twice to the left

-
150%. Change to a decimal.

-
6.5%. Change to a decimal.

Mini-lesson/review:
converting between percents, decimals, or fractions

•   Fractions can be simplified then converted to
decimals. The decimal can be left as is or converted to a %.

•   Sometimes you create your own fraction from
information in problem

-
3 wins, 5 losses. % of total games lost?

-
3 wins out of 5 games total. % of games lost?

•   One problem. % blue beads out of total. Put in
order.

GP: solicit
student input here. Try to do all 3 in 10 minutes. If you don’t get through
all 3, stop and allow kids to move on to Independent Practice.

1. Quick refresher on
Friday’s compare and order materials. Here’s a word problem, let’s read
it carefully. <<do this yourself without soliciting any input.
Careful of the word incorrectly.
Change all to percents. Pay attention to the question stem. A. is a
distractor because it lists them from least to greatest.>>

1. Below are times in a
table. List from slowest to fastest

1. Compare 4 numbers: -12,
1/2, 1.2%, 1.2

SILENT. No hands. Use your resources and notes, and
circulate around. Do not take questions! Students have permission to start on
exit ticket first to make sure it’s done.
