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

Do Now
<<Call to Begin>> 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 math minute, so when you have a seat be ready to share your answers from the Do Now. Good morning.

Answer #1 yourself. Solicit some hands on #2: share data on exit ticket answers!
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.
Minilesson/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.
 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.>>
 Below are times in a
table. List from slowest to fastest
 Compare 4 numbers: 12,
1/2, 1.2%, 1.2
IP: (6 problems—4 MC, 2 short answer) 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.
Exit Ticket (task 27—both MC)
 Once finished, tear off and continue with task 26.
