How to Use This Book
The new Forde-Ferrier math workbooks are designed to provide practice
items in the format and with the rigor of the STAAR math assessment for all
the updated 2014 math TEKS. Practice is provided for each new math
student expectation with entire sets based the Readiness Standards
(Supporting Standard are grouped by Reporting Category into their own
sets). The items for each set are divided into sections as follows:
Introduction (10 Items) – These items could be used to introduce and
explain each skill.
Practice (10 items) – These items could be used for guided practice or
independent practice, or to continue introducing the skill.
Assessments (10 items) – These items could be used to assess mastery of
each skill.
Enrichment (2 items) – These items are designed to truly challenge
students. They could be used for enrichment, differentiated instruction,
bonus work, homework, or cooperative group work.
Student mastery of the assessments helps ensure mastery of the STAAR
math test.
As with any workbook, this items are intended to supplement, not replace, a
thorough math program. Mastery of math items is dependent upon the
classroom teacher – no math workbook can “teach” the student how to solve
problems. A quality math program is essential to student success on the
STAAR math assessment.
The suggested uses of each section are just that – only suggestions.
Teachers are encouraged to use the items in the best way they feel will help
their students master each math skill.
Forde-Ferrier also provides math training on the new 2014 TEKS. We also
provide model lessons and intervention programs. The intervention programs we provide have produced significant increases in STAAR scores
for campuses that have implemented them. Contact us at Forde-Ferrier.com
for more information.

Assessment
1 A research team conducted a study of pairs of childhood friends (of the same age) over
a period of 50 years. The researchers surveyed the friends at different stages in their
lives in order to determine how much the friends had in common with one another at
each life stage. The ‘commonness rating’ was determined by how closely the friends’
answers matched one another when they took the surveys separately. The survey
questions remained the same throughout the study. Very few of the childhood friends
maintained close friendships as adults. However, this fact did not disqualify them from
the study. The results of the study are recorded in the table below.
Age When Surveyed Commonness Rating
7 75%
13 84%
18 75%
27 65%
35 53%
50 58%
57 56%
Which of the following statements is directly supported by the data?
A Adults have less in common than children.
B People change over time.
C People’s different life experiences make it harder to understand one another as
they age.
D Childhood friends will have practically nothing in common with one another once
they reach 90 years of age.

2 Principal Evans read an education journal that claimed that students could boost their
reading level by an average of 2 years in 9 months if they read 30 minutes each day.
Principal Evans had all students at his school read for 30 minutes each day. The
reading progress of the 8th graders at Canyon View is recorded in the table below.
Year of
Implementation
Average Reading Level
(Beginning of Year)*
Average Reading Level
(End of Year)*
Year 1 5.4 6.1
Year 2 5.6 6.5
Year 3 6.3 7.0
The digit in the ones place represents the grade level by year. The digit in tenths place
represents the number of months into the school year. Example: A score of 6.5 would
indicate the reading level of an average 6th grader during the 5th month of school.
Which of the following statements is NOT supported by the data in the table?
A Either the claim that Principal Evans read in the journal was wrong or it is unlikely
that the 8th grade students been reading for 30 minutes each night.
B The data shows that the students received no benefit from Principal Evan’s new
reading assignment.
C The data shows that 8th graders showed more reading readiness at the start of
Year 3 than they had in the past.
D The data shows that student reading skills level off after 3 years.

Use the information below to answer the next two questions.
Green Valley ISD is considering adopting a healthier cafeteria menu. A neighboring
district adopted a plan similar to the one Green Valley ISD is considering. The district
found that overall food waste increased by 25% as more students chose to dump their
healthier meals rather than eat them. Waste increases were highest among green
vegetables and bananas.
3 The neighboring district reported that the greatest increase in food waste occurred
when it replaced a popular taco salad with a Mediterranean salad. Food waste went
from 7% to 45%. Green Valley ISD serves an average of 6,500 lunches a day. If the
waste increase in the neighboring district is used to predict the increase in food waste
that might occur at Green Valley ISD, approximately how many meals might be wasted
if Green Valley decides to make the same switch from taco salad to Mediterranean
salad?
A 2,000 meals
B 2,500 meals
C 3,000 meals
D There is not enough information available to answer the question.
4 The neighboring district found that it threw out an average of 550 more cartons of milk
than it had in the past once it stopped serving chocolate milk. Using this data to make
a prediction, how many additional cartons of milk can Green Valley ISD expect to see
wasted each day if it decides to discontinue serving chocolate milk?
A 550 cartons
B At least 550 cartons
C Less than 550 cartons
D There is not enough information available to answer the question.

1 A middle school student conducted an experiment to test for the amount of sugar in a
leading soft drink beverage. The student hypothesized that any given volume of the
soda would have the same amount of sugar. Also, the same sugar to water ratio
should be present whether the soda was purchased in a 12 oz. can, a 20 oz. bottle, or
a 1 liter (33.8 oz.) bottle. To determine the sugar content, without reading the labels,
the student poured the 3 soda samples into separate containers. The student then
waited for the liquid in the soda to evaporate. The weight of the sugar left in the
containers was then measured. The results of the first 3 trials are recorded in the
table below.

The student found a problem with his results and repeated the test. The second set of
data produced the results that the student expected, allowing him to conclude that the
experiment had been a success. What was it that the student could have noticed in
the data table that might have caused him to doubt his initial results?
A The student questioned whether it had been acceptable to convert liters to fluid
ounces.
B The samples of soda would have evaporated at different rates, causing the data to
be invalid.
C There was a noticeable inconsistency in the liquid to sugar ration in one of the
soda samples.
D The student realized that the carbonated bubbles in the soda affected the
evaporation of the liquid.

2 While visiting her grandparents in the country, Karen learned that crickets’ chirps can
be used to approximately measure the outside air temperature. Karen used a formula
that required one to start by counting chirps and then adding a number, but she
couldn’t remember how long to count or what to add. Karen decided that she would
try to discover the formula on her own using a thermometer and a stopwatch. She
recorded the data from her experiment in the table below.
Length of
Chirping
Number of
Chirps
Mystery
Number to Add Temperature
15 Seconds 31 ? 68°F
30 Seconds 62 ? 68°F
45 Seconds 93 ? 68°F
60 Seconds 124 ? 68°F
The information that Karen recorded will support the formula. Which of the following
investigative approaches will help Karen find the formula?
A Karen can ignore the data for the two longer times because the number of chirps
are too high to add up to 68. All she has left to do is determine which numbers
will need to be added to 31 and 62 to make 68. Karen can then determine which
answer is more reasonable.
B Karen will need to work backward by subtracting the numbers of chirps from the
temperature. This will give her four possible choices for the mystery number.
One of the choices will be the correct number. Karen will then need to wait for
the temperature to change and repeat the experiment.
C Karen must use algebraic thinking to determine what numbers to add to the
numbers of chirps to equal the temperature. In the event that the numbers of
chirps is greater than the number representing the temperature, Karen must
subtract instead of add. The mystery numbers that this process generates will all
be valid, but it would be best to count for 60 seconds because the longer time
increases the accuracy of the data.
D Karen should focus on the 15 and 30-second timeframes because they will make it
easier to keep track of the number of cricket chirps. Karen will then need to
determine which numbers will need to be added to the number of chirps in order
to match the temperature. Once this is done, Karen will need to wait until the next day and repeat the experiment when the temperature reaches 68 °F.
