Mrs. Garnerユs classroom had 25 desks. They were arranged in 5
rows that each contained 5 desks.
Write the fraction of the desks that are in Row 1. Write this fraction
as a percent. Show or explain your work. Another classroom has
between 15 and 22 desks with the same number of desks in each
row. Row 1 has 25% of the desks in this classroom. Draw an
arrangement of the desks in this classroom. How many desks are
in Row 1? (4 points)
A 500
There are 5 desks in Row 1 and a total of 25 desks. This means that
the portion of desks in Row 1 is 5 out of 25, or . This fraction can be
written as a decimal by dividing 5 by 25 (). The decimal can then be
written as a percent by multiplying 0.20 by 100 () because all
percents are out of 100. So, .ハTo draw the arrangement of desks,
students need to know how many desks there are in total. Row 1 has
25%, or one-fourth, of the total number of all desks. This means that
the total number of desks must be a number between 15 and 22 that
is divisible by (can be divided by) 4. The possible number of total
desks is 16 (4 in each row) or 20 (5 in each row).
The focus of this task is generating equivalent forms of fractions and
percents. The response includes the correct fraction and percent for
the number of desks that are in Row 1 out of 25 total desks. The
response also provides a drawing representing an arrangement of
desks for 25% of the desks between 15 and 22 and identifies the
number of desks in row one.

A class needs 64 brownies for a bake
sale. Mike brings 28 brownies.
Write two number sentences using
different operations to find the number of
brownies the class still needs for the bake
sale.
D 500
Students need to give two different number sentences that
show the number of brownies the class still needs for the
bake sale. In this case, the two operations that students can
use are addition and subtraction. Because 64 brownies are
needed and Mike brought 28, a number sentence that
shows the situation is , where n is the number of brownies
still needed for the bake sale. Because the inverse
(opposite) of subtraction is addition, the number sentence
can also be written as
.
The focus of this task is identifying and using relationships
between operations to solve problems. The response
provides two correct number sentences that use different
operations.

Please record your wager.

The diagram shows how far it is from Anna’s home to her school, from
her school to the library, and from the library to her home.
Each school day, Anna rides her bike from her home to her school.
After school, she rides to the library and then home. On Saturday, Anna
rides her bike from home to the library and back
home. She does not ride her bike
on Sunday. Anna’s mother says
that her daughter rides about 30
miles every week between her
home, the school and the library.
Use estimation to determine
whether Anna’s mother has made a
reasonable estimate. Show or
explain your work.

Students should be able to estimate these decimals to the nearest
whole numbers:
0.87 rounds to 1
1.8 rounds to 2 miles
0.92 rounds to 1
During the week she rides 0.87 to school, 1.8 miles to the library, and
0.92 from the library to home. This is about 1 mile, 2 miles, and 1
mile, or a total of 4 miles every day. Anna rides 4 miles each day 5
days a week, or 5 x 4 = 20 miles. On Saturday, she rides about 1 mile
to the library and about 1 mile back to her home. This is an additional
2 miles a week, for a total of 22 miles.
Anna's mother estimated 30 miles, which is a lot more than 22 miles,
so Anna's mother is incorrect. A better estimate would be 20 miles a
week.
