Quarter 4 Curriculum Overview*
4th Quarter: 43 days
All of the skills acquired during the 4th quarter will better prepare eighth graders for Algebra 1. These skills are part of the Core Learning Goals and will be tested on the HSA.
High school algebra teachers say that students come to high school not prepared with the basic fraction, decimal, and percent concepts. During this quarter, go back and review these skills to make sure that students are prepared for high school.
The June Benchmark will test all of these skills in the 4th quarter as well as the other skills from Quarters 1, 2, and 3.

4th Quarter Curriculum Guide April 2008This 3-part curriculum guide is designed to assist you in helping your students meet the requirements of the Maryland Voluntary State Curriculum (VSC). This curriculum is in paper form, on CD, and on TSS. Updates will continually be made to the curriculum document on TSS and therefore, you are encouraged to download the revised document on a regular basis. We welcome your feedback via email at officeofmath.bcps.k12.md.us. AssessmentsAssessing students’ needs is the key to a successful math program. Unit 1 assessments are included. Other types of assessments will be available online. Requiring students to SHOW WORK on all problems will enable you to see students’ thinking and better analyze errors. All assessments are directly aligned with the MD VSC. The VSC objectives and numbers are also listed in this section. For concepts that are new or are being extended, the VSC objective for the next grade level has been used. The VSC objective number starts with the grade level followed by the standard.
Concept Assessments are provided with an on-line tracking sheet that will allow you to track the progress of each student in order to provide differentiated instruction for students who did not initially master the concept. There are many other ways that you can assess students’ progress. Choose methods that are effective for you and your students. Unit assessments provide evidence of student achievement for the content of each unit. On-line data analysis sheets will help track student progress.
The June Math Benchmark will assess students’ knowledge from the fourth quarter as well as those skills that are essential for the next grade level.
Knowledge and SkillsThis section includes a range of time to teach each concept based on students’ needs. This is a suggested time that it might take for students to master a concept. For that reason a calendar is provided so you can plan your quarter. The sum of the days in the upper range will exceed 43 days. Therefore, adjust your instructional plan accordingly. Prerequisite skills as well as sub-skills are indicated for each concept. Take time to revisit prerequisite skills and add sub-skills as needed.
.
New means that this is the first time that the concept has been introduced to students. Review means that it was taught previously but is important to revisit again to make sure that all students have mastered it. Extension means that the skill has been taught previously, but the assessment limit has been extended to the next grade.
Vocabulary words are important in developing an understanding of a concept, but they should be introduced along with the concept and never in isolation. On-line vocabulary links are provided to develop and reinforce the meaning of these words.
Enduring Understandings are the “Big Ideas” that need to be retained for a lifetime. Samples have been included as a starting point; add more as the concept develops. Sample Essential Questions have been included to help frame your daily instruction. Concept Knowledge is the basic information that students need to know in order to understand the concept.
Error Intervention suggestions, also known as “Hot Spots”, help identify the problems students might have and possible ways to prevent them.
The Learning PlanThis section includes various activities and strategies that can be used to motivate the students, and to introduce, teach, or reinforce each concept. On-line links to access additional activities and resources are provided.
The math textbook and Math Works have great ideas, information, and materials, but should not be the only source for your learning plan. You are the key in developing a learning plan to engage all students and ensure that they master the concepts.
. A special thanks to all the teachers, IST’s, and administrators who wrote, revised, and provided feedback for our curriculum.
*The Quarter Overview lists the concepts students must master in the 4th quarter. Suggested time frames are provided; however, each teacher has the responsibility to make choices to adapt the timing and sequence of units based on student needs as identified by data.

ENDURING UNDERSTANDINGS Whole numbers and their opposites are integers. Zero is a whole number so it is an integer (but
called the origin). Comparisons can be absolute or relative. The further a number gets away from 0 on the negative side, the smaller it gets; the further a
number gets away from 0 on the positive side, the larger it gets.ESSENTIAL QUESTIONS How is a number line useful in comparing integers?CONCEPT KNOWLEDGE A number’s absolute value is the distance it is away from zero (it is always positive because it
literally is just counting the spaces away; the direction does not matter). Absolute value is shown with straight bars .
Negative numbers are less than 0 and written with a negative sign (-17). Positive numbers are more than 0 and usually written with no sign (17).
ERROR INTERVENTIONStudents make negative numbers positive and positive numbers negative when finding the absolute value…
Have them draw a numberline and count how many spaces the negative number is away from zero out loud. Point out how when counting we don’t say -1, -2, -3, etc.
Students confuse negative numbers with a larger absolute value as being greater than other negative numbers with a smaller absolute value…
Relate the numbers to real-world contexts like temperature for them to see why numbers like-14 are actually smaller than -2, even though they “appear” bigger.

ENDURING UNDERSTANDINGS Integers add to the concept of number the idea of opposite, so that every number has
both a size relationship and a positive or negative relationship to other numbers.ESSENTIAL QUESTIONS What examples show how adding integers is used every day?CONCEPT KNOWLEDGE Adding integers, unlike whole numbers, can make a number smaller if you are adding a
negative number to another number. Adding numbers with the same sign (pos. or neg.) means you literally will add the amounts
together and the sign will stay the same. Adding numbers with different signs (pos. plus neg.) means you will subtract the amounts.
The sum of any two numbers, positive or negative, is decided by which number has a higher absolute value.
ERROR INTERVENTIONStudents add the numbers no matter what…
Model how adding positives will look on a number line. Next, model by adding two negatives and making real-world connections (i.e. debt, temperature drops), then model a negative number added to a positive number.
If students are assigning the wrong sign to the number…
Have them model the problem using +1 and -1 algebra tiles to see which there are more of when adding to see what sign the answer will have.

ENDURING UNDERSTANDINGS Integers add to the concept of number the idea of opposite, so that every number has both a
size relationship and a positive or negative relationship to other numbers.ESSENTIAL QUESTIONS What examples can be used to show the meaning of subtracting integers?CONCEPT KNOWLEDGE Subtracting integers, unlike whole numbers, can make a number SMALLER OR BIGGER! Subtracting a positive number means you are taking away more and the number gets smaller. Subtracting a negative number means you have two negative signs that cancel each other out
and become a positive! Subtracting a number is the same as adding its opposite.
ERROR INTERVENTIONStudents are having trouble understanding that subtracting a negative makes a positive…
Discuss a real world example like, “The temperature dropped from -3 to -11 degrees; what is the difference between these two numbers?”
Students are simply subtracting normally (i.e. -9 – 1 = 8)…
Have students ALWAYS rewrite the problem verbally first, with the minus sign translating to “and the opposite of,” and then translating to numbers. Ex.:
-5 - (9)= Negative 5 and the opposite of (9) -5 + (-9) = -14

ENDURING UNDERSTANDINGS Mathematically, ideas can be represented numerically or symbolically.ESSENTIAL QUESTIONS What are ways that the multiplication and division of integers can be shown?CONCEPT KNOWLEDGE The product of two numbers is the same as repeating addition
(i.e. -3 5 = -3 + -3 + -3 + -3 + -3). The quotient of two numbers is the same as breaking a number into equal groups
(i.e. -10 / 2 = -5 in one group, -5 in another group). The product or quotient of numbers with the same sign (both positive or both negative) is a
positive result; the product or quotient of numbers with different signs (one positive, one negative) is a negative result.
ERROR INTERVENTIONStudents mistake the sign in the answer but multiply correctly…
Have students make a key that they can keep on their desk with + and – signs showing the rules (+ times - = neg.; - times - = pos.).
Students are having trouble with just mutliplying and dividing normally…

CONCEPT KNOWLEDGE The description that tells how a pattern changes from any given frame to the next frame is
known as the recursive relationship. Growing, geometric patterns have a visual component and/or a numeric component that
students should analyze using a table. From here, they can figure out the “rule/relationship” to help predict the nth term in a series. (Process Chart)

CONCEPT KNOWLEDGEAn expression names an amount
Sometimes an expression is just a number, like 5. Sometimes an expression is just a variable, like n. Sometimes an expression is a combination of numbers, variables, and operations
like 2 3 or y – 6.There are two main types of expressions:
Algebraic – which include variables AND numbers. Numeric – which include JUST numbers (Process Chart)

ENDURING UNDERSTANDINGS An expression can be written in a variety of equivalent ways.ESSENTIAL QUESTION How can expressions be simplified?
CONCEPT KNOWLEDGESimplifying an expression means to combine terms so that there are less terms in the expression. When simplifying, GEMDAS still should be followed (multiply terms together, before, addition,
etc.). Terms can only be added together if they are like terms (share a common variable set) or are
constants (numbers that don’t vary). To add like terms, you add the coefficients together. Any two terms can be multiplied or divided together (Process Chart).ERROR INTERVENTION
Students multiply the coefficients together when adding like terms instead of adding them…
Have students write out what each term is as repeated addition above the terms(i.e. 4x means x + x + x + x).
Students struggle with the computation of rational numbers…
Give them a calculator; however require them to write down each step for the problems they used the calculator for so that you can see their work.

Teacher DefinitionsStudent Vocabulary SheetWord Wall VocabularyTotal Vocabulary Matrix
ENDURING UNDERSTANDINGS Linear functions show a pattern of growth.
ESSENTIAL QUESTION What are ways that you can prove the solution is correct?
CONCEPT KNOWLEDGE To solve an equation means to isolate the variable so that it is “alone” (having a coefficient
of 1). To ISOLATE the variable, you need to “undo” the problem by working backwards to find the
missing variable (Process Charts-Solving One-Step equations ; Two- to Three-step equations).
When solving equations, you must always BALANCE THE EQUATION (you have to do that same operation with the same number to the other side).
To check a solution, substitute the value you found back into the original equation to make sure both sides are equal.
There are some equations that have “no solution” or could have an infinite number of solutions.
