A student was confused as to where to place the decimal point in
the result of the product 24.5 x 0.02. Which of the following
activities would best help the student understand decimal point
placement when finding the product of two decimal numbers?
a. practicing counting decimal places in decimal numerals
b. converting decimals to fraction equivalents and finding the
fraction products
c. finding decimal products on a calculator and recording the
results
d. adding zeros to decimal numerals so that they have the same
number of decimal palces - ✔✔✔ Correct Answer > b. converting
decimals to fraction equivalents and finding the fraction products
During a unit on pollution, a teacher in an upper elementary
school classroom led a student's discussion about an article in
the local newspaper on a decision to ban swimming and other
recreational activities in a local pond that was found to contain a
,Page 2 of 111
high level of pollutants. The teacher engages students in
research projects related to the problem of the polluted pond.
The class will be divided into small groups, each group
responsible for researching a relevant topic. The teacher can
best promote students' social science inquiry skills by taking
which of the following actions first?
a. leading the class in brainstorming ideas about possible causes
and effects of the pollution found in the pond
b. helping students in each group define one or more essential
questions they would like to answer about the pond
c. having students with prior personal experience of the pong
talk to the rest of the class about their experi - ✔✔✔ Correct Answer >
b. helping students in each group define one or more essential
questions they would like to answer about the pond
A student consistently simplifies algebraic expressions as shown
below.
2x + 3x + 5 = 20
10x = 20
x=2
This provides the most direct evidence that the student does not
understand which of the following mathematical concepts?
,Page 3 of 111
a. commutative property of multiplication
b. distributive property of multiplication over addition
c. division as the inverse of multiplication
d. associative property of multiplication and addition - ✔✔✔ Correct
Answer > b. distributive property of multiplication over addition
Use the problem and student work shown below to answer the
question that follows.
Simplify: 2x+5=3(x-1)
Student work:
Step 1: 2x+5-3(x-1)=2x+5-3x+3
Step 2: 2x+5-3x=2x-3x+5+3
Step 3: 2x-3x+5+3=(2-3)x+5+3
Step 4: (2-3)x+5+3=-x+8
Which of the following properties justifies step 2 in the students
work?
a. associative property
, Page 4 of 111
b. closure property
c. commutative property
d. distributive property - ✔✔✔ Correct Answer > c. commutative
property
A teacher has students modeling the integers from 2 through 20
creating rectangular arrays using square tiles. The students
notice that some numbers can be modeled using different arrays;
for example, 8 can be modeled with a 2 by 4 array and a 1 by 8
array. If only one array is possible for a given integer n, where n
> 1, then it must be true that n is:
a. odd
b. even
c. composite
d. prime - ✔✔✔ Correct Answer > d. prime
A hotel charges $3325 per week for a room during peak season.
Which of the following expressions can be used to determine this
cost in dollars per minute?
a. 7days/3325 dollars x 24hrs/1 day x 60min/1hr
b. 3325dollars/7days x 24hrs/1day x 1hr/60min
