4th Grade
2011 – 2012 School Year
Dear Colleague, Please use this curriculum guide to assist in your unit, lesson and assessment plans as you progress through the school year. As additional guidance, included below is further clarrification regarding the “Content Key” symbols used throughout this document:
Content Key Description
√ Grade Level Content Content that is part of the current grade level set of standards. Students should be assessed fully on their ability to demonstrate an understanding of these concepts.
Previous Content
Content that was part of a previous grade level set of standards. Students should be assessed fully on their ability to demonstrate an understanding of these concepts. You may be able to condense material here based upon your students maintained knowledge of this information.
Exposure Content for Future Study
Content that is part of a future grade level set of standards. Students should be assessed, at an exposure level, on their ability to demonstrate an understanding of these concepts. It is not expected that all students develop a mastery level of understanding of these concepts at this time.
Additionally, in preparation for the upcoming implementation and transistion into the Common Core State Standards (CCSS), it is imperitative that we begin fostering the mathematical mindsets and practices of our students that are embodied within these new standards. Also within these standards, there will be a stronger emphasis placed on specific areas of study. In following the guidance of the New York State Education Department, as a district, we have decided to plan for an intensive focus of study to occur within the topics of the meaning and understanding of fractions and decimals. Time will be made available to develop these units of study (topics 10, 11 and 12) together with district colleagues.

1-5 Using Money to Understand Decimals
1-6 Counting Money and Making Change
The focus of this lesson is counting up to make change. The focus of this lesson does not include the subtraction algorithm. Students should be encouraged to use money manipulatives to assist them when making change. Supplementation may be necessary. Consider utilizing the center activities for this lesson. Allow opportunities for students to demonstrate an understanding of this concept before moving on.
• A number in the thousands can be represented with place-value blocks or a number line. A number can be written in standard form using digits only, expanded form by writing the sum of the value of the digits, or word form using periods from a place-value chart.
• Our number system is based on groups of ten. Whenever we get 10 in one place value, we move to the next greater place value.
• Place value can be used to compare and order numbers.
• Rounding whole numbers is a process for finding the multiple of 10, 100, and so on closest to a given number.
• Relationships among dollars, dimes, and pennies are a good model for decimal numeration.
• When counting money, it is often easiest to start with the bills or coins that have the greatest value. Counting up is usually an efficient way to make change.
• Some problems can be solved by generating a list of outcomes and organizing that list in a systematic way so all outcomes are accounted for. 1-7

• A fraction can be expressed in its simplest form by dividing the numerator and denominator by common factors until there are no common factors other than 1.
• Fractional amounts greater than 1 can be represented using a whole number and a fraction. Whole number amounts can be represented as fractions. When the numerator and denominator are equal, the fraction equals 1.

• To subtract with unlike denominators, change to an equivalent calculation with like denominators.
• Information can often be shown using a diagram by writing and completing a number sentence or equation.
• Techniques for estimating calculations with whole numbers can also be used to estimate calculations with decimals.
• Multiplying a whole number by a decimal is similar to multiplying two whole numbers. Estimation and place value can determine the location of the decimal point in the product.
• Dividing a decimal by a whole number is similar to dividing two whole numbers. Estimation and place value can determine the location of the decimal point in the quotient.
• Some problems can be solved by making a reasoned first try for what the answer might be, and then by using additional reasoning to arrive at the correct answer.

• Relationships between metric units can be expressed as a ratio (e.g., 10mm to 1 cm or 1 mm = 1 cm). Relationships exist that enable you to convert between metric units of the same attribute by multiplying or dividing.
• Temperature can be expressed using degrees Fahrenheit or Celsius. Temperature change can be found using addition or subtraction.
• Some problems with the initial data point unknown can be solved by starting the end result and by reversing the steps and processes work backward to find the initial data point.
• Each type of graph is most appropriate for certain kinds of data. A line plot organizes data on a number line and is useful for showing visually how data are distributed.
• The Cartesian Coordinate System is a scheme that uses perpendicular number lines intersecting at zero on each axis to name the location of points in the plane.
• There is more than one way to describe the center or typical number in a numerical data set. The mean is the average of a set of numerical data.
• There is more than one way to describe the center or typical number in a numerical data set; median and mode are two ways. Range is one way to describe how data are distributed.
• Each type of graph is most appropriate for certain kinds of data. Stem-and-leaf plots can be used to show how data are distributed.
• Each type of graph is most appropriate for certain kinds of data. A circle graph is most appropriate for certain kinds of data. A circle graph shows how portions of a set of data compare with the whole. 17-9 Reading Circle

• Two algebraic expressions are equal if the value of each expression is the same when each variable is replaced with its assigned number and the resulting calculations are completed.
• A solution to an equation is a value of the unknown (or unknowns) that makes the equation true. Equations of the form x + a = b or x - a = b can be solved using properties of equality and inverse operations.
• Equations of the form ax = b or ______ = b (a ≠ 0) can be solved using properties of equality and inverse operations.
• Some problems with the initial data point unknown can be solved by starting with the end result and, by reversing the steps and processes, work backward to find the initial data point.
