A parallelogram is shown on the grid.
1) Which expression
represents the area of
this parallelogram?
A. 6 + 6 + 4 + 4
B. 8 + 8 + 4 + 4
C. 6 × 4
D. 8 x 4
1) Which expression
represents the area of
this parallelogram?
A. 6 + 6 + 4 + 4
If a student chooses A, he or she may
confuse perimeter and area and may find
only the perimeter of the rectangular part of
the parallelogram.
B. 8 + 8 + 4 + 4
If a student chooses B, he or she may
confuse perimeter and area and may find
only the perimeter of the parallelogram.
C. 6 × 4
If a student chooses C, he or she may find
only the area of the rectangular part of the
parallelogram.
D. 8 × 4
This is the correct answer.
Students can find the correct area by
counting all the squares on the inside of the
shape.
Han
compared
the angles
on this
diagram.
2) Which angle appears to
be greater than 90°?
A.
B.
C.
D.
LJN
MJN
KJM
KJN
2) Which angle appears to
be greater than 90 ° ?
A.
LJN
If a student chooses A,
he or she may not understand that the
measure of LJN appears to be 90°, not
greater than 90°.
B. MJN
If a student chooses B, he or she may not
understand that the measure of MJN is
less than an angle that is 90º.
C. KJM
If a student chooses C, he or she may
confuse a 90º angle with a 45º angle and
chooses an angle greater than 45º.
D. KJN
This is the correct answer.
Angle LJN is 90º, and angle KJN is
greater than 90º because the ray JK is
rotated slightly to the left of ray JL.
Julia ran a 6-kilometer race
on a 400-meter oval track.
3) How many laps around
the track did Julia run?
A.
B.
C.
D.
0.15 lap
1.5 laps
15 laps
150 laps
3) Julia ran a 6-kilometer race on a 400-meter
oval track. How many laps around the track
did Julia run?
A. 0.15 lap
If a student chooses A, he or she may think
that 6 kilometers equal 60 meters and may
divide 60 meters by 400 meters.
B. 1.5 laps
If a student chooses B, he or she may think
that 6 kilometers equal 600 meters and may
divide 600 meters by 400 meters.
C. 15 laps
This is the correct answer.
The first step is knowing that 6 kilometers
equal 6,000 meters. The next step is dividing
6,000 meters by 400 meters, which gives the
correct answer of 15 laps.
D. 150 laps
If a student chooses D, he or she may think
that 6 kilometers equal 60,000 meters and
may divide 60,000 meters by 400 meters.
