###### Content Objective:

Over the last 5 years, for fourth grade, in my district, the Pennsylvania State Standard Assessment (PSSA) data for mathematics has steadily declined. The data shows a large learning gap in measurement, especially measurement that involves fractional portions. For several years, this same area of instruction has also proven difficult for students within my own fourth grade classroom.  The lack of conceptual understanding has prompted me into further study as to where the misconceptions of measurement are occurring.  I began to research outside the school district and state to identify if this situation is occurring in other classrooms around the country.  I located an article from the New York Times dated October 30, 2015, whose author, Liana Heitin, describes in great detail the decline throughout the United States in standardized test scores for math and reading.  Examining the data within this article I learned that one of the larger areas in the math decline is around measurement.  In his book, “Measurement in Early and Elementary Education”, Douglas Clements states, “measurement knowledge and strategies play broadly and deeply into children’s understanding of both science and mathematics.” In Chapter one of the book it also states the necessity of working through the elements of theoretical foundation in measurement. As fractions are a vital part of all types of measuring situations, it is imperative that students are able to clearly understand and be able to apply this concept to everyday tasks. It’s not only important in length measurement, but in liquid, weight, and volume measurement as well.

I went back and studied the scope and sequence of our school district requirements as to the grade level and concepts of measurement which must be taught. Students are taught fractions beginning in grade 1; however, the use of fractional portions in a real-world situation does not occur until third grade. At this point, the required instruction in the scope and sequence is limited to: placing fractions on a number line by quarters, comparing unit fractions and ordering fractions with like denominators. Therefore, students are entering fourth grade with limited knowledge and application of fractional portions as it relates to measurement. Considering the lack of conceptual understanding, which would provide a formatted baseline to be built upon, instead, is a concept that needs to be re-taught and expanded upon. A lack of basic mathematical understanding, compounded with the shortage of resource materials in our district, adds to the challenge of teaching the concept of measurement with fractional portions.

Over the last 18 years of teaching mathematics, I have noted that students demonstrate large gaps in their understanding of number sense.  This prompted me to seek alternative teaching methods beyond what my district provides in resource materials and professional development opportunities.  It is important to me, as an educator, to make sure I teach to all the modalities and ensure my students are obtaining the knowledge needed for success.  Therefore, I needed to find resources and professional development seminars that I could utilized in assisting my students and create a structure of knowledge which will enhance understanding and provide them with the ability to apply concepts.  To assist in achieving this goal and extended my knowledge, I became a fellow at the University of Pennsylvania Teachers Institute of Philadelphia as a participant in the course visualization of mathematics.  The course is based on designing and implementing many different forms of visual components to assist students in gaining a better understanding of why and how a concept is applied.   Instruction which includes a visual component will provide students another way to absorb knowledge.

Another method that includes a visual component is exploring using manipulatives or a hands-on method. This is an additional way a student can visualize how numbers work together, giving a window into the true number sense needed to formulate a sum or answer for an equation.  This also provides students an additional strategy as they approach the idea that numbers are more than just numbers.  Students need to visualize why numbers are in a specific place, then manipulating those numbers within those place value positions, to show equivalency.  Students also need to realize that the four mathematical operations are interchangeable (i.e.:  addition and multiplication, subtraction, and division).  Teaching through visualization gives students the opportunity to see exactly why and how these interchanges occur.

There are several objectives for this unit.  The first objective will include students having an increased knowledge of number sense.  The next objective stated is students will be able to utilize knowledge of vocabulary and conversion equivalents, in order to solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit and smaller unit to larger unit.  Then, students will be able to convert standard measurement in a larger unit in terms of a smaller unit, to record measurement equivalents in a two-column table.  Finally, students will be able to use four operations to solve word problems involving distance, involving simple fractions and problems that require expressing measurements given in a larger unit in terms of a smaller unit, in order to represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

###### Teaching Strategies:

There are four; ninety-minute lessons in this unit. All the lessons are equipped with small group instruction for those students who need additional reinforcement. Several suggested methods to assess that students are developing learning will include, teacher observation, an exit ticket for the end of each lesson, finally a culmination of all concepts learned will be assessed with a formal test.

In this unit, I will be focusing on the use of visualization as a guide to assist students in envisioning how and why, the parts of a whole work in conjunction with one another. To accomplish this task, I will take into consideration the learning styles, language barriers, and learning disabilities in which students may exhibit. To enhance the student’s interest and willingness to participate in their learning, I will be utilizing read aloud books, group interactive lessons, power point presentations, and manipulatives/rulers to meet the needs of the multi-intelligent styles.

This unit will focus on teaching students several strategies involving fractional measurement beginning with the complex vocabulary utilized in measurement and fractional equations. The lessons will include standard measurement, vocabulary, fractional portions, and conversion of measurement. Included in this unit are auditory, visual, and concert variations to enhance students understanding also giving students the ability to apply concepts when solving real-world equations. Incorporated in this unit are lessons where students will listen to a read aloud story, “How Big is a Foot?” which deals with a measurement conundrum. They will experience visualization through power point presentations, which will demonstrate how fractional portions are part on one whole.  The process of how conversion of measure is linked within inches to feet, and feet to yards, etc, will also be demonstrated through the visual medium of power point presentations. The creation of anchor charts, as an additional resource for students to utilize, will include vocabulary, fractional portions of a ruler, and conversion equations.  These charts will assist student when completing assignments.  The use of manipulatives will be integrated as students work with their small groups assisting one another with the task of measuring.

To implement this unit, the materials suggested are: (1) chart paper to create vocabulary anchor chart, and a chart showing conversion equations; (2) next, a ruler copied onto oak-tag, or stock paper, along with colored pencils — these will be utilized through out the unit.  Then, (3) a twelve-inch ruler for each student and several yard sticks for each group.  In addition, (4) index cards can be used to create exit tickets for each lesson.  Finally, (5) students will need some type of composition book to make notes and solve equations.  There are several worksheets in the appendix of this unit that can be utilized with each lesson.

###### Classroom Activities:

Lesson One Powerpoint

Meaurement to fractional portions Powerpoint

Lesson One addresses the common core standard 4.MD.A, the use of a read aloud “How Big is a Foot?” will be used to activate background knowledge about measurement. To continue the process of background a vocabulary anchor chart will be created.  This chart will include, both the entire word, as well as, the standard abbreviation for each word.  These charts should be placed in a convenient location as a future student resource.  Next, the students will have a hands-on opportunity to maneuver one-inch sections along the twelve-inch ruler.  Then, students will work in groups using one another’s ruler to prove how three twelve-inch rulers make one yard.  These activities are to prepare students to understand the conversion from inches to feet and feet to yards.   The exit ticket for this lesson will offer insight into the students’ understanding or misconception of the conversion method. Lesson Two focuses on common core standard 4.MD.A.1 the conversion of one type of measurement to another.  Students will be able to apply learned concept of calculating measurements from one form to obtain measurement of a different form. To assess student knowledge of this concept, pass out an index card with a pre-printed conversion chart for student to complete.  The exit ticket should require students to show their work!

The focus for Lesson three is the common core standard 4.MD.A.2 which requires students to measure using fractions parts.  The classroom activity to meet this standard is to have students color coordinate their paper rulers.  The use of color coordinating fractions as specific points on the paper ruler will give students a focal point to relay upon for standard measurement.  Along with this activity, each group will be given sets of fraction bars to manipulate in guided practice.  To assist students with where and how to locate fraction parts on the ruler a power point presentation is provided. The exit ticket for this lesson will be to have students draw a line first; then they will need to measure the line and plot the points of the measurement.  Finally, they will need to give the exact total measurement of their line. Lesson four teaches students the standard 4.MD.A.2 which wants students to use the four operations to solve word problems involving distances.  To achieve this objective a student must have prior knowledge involving addition, subtraction, multiplication, and division.  It is also recommended that students have a good understanding surrounding the concept of how to obtain information within the word problem to solve it correctly.  To begin place a word problem on the board and read the problem all the way through with the entire class.  Then go back and slowly re-read the problem as you circle or highlight the numbers needed and underline the question.  Next, have students discuss the mathematic operations they would use to solve this equation.  Have a student volunteer come to the board and solve the equations, explaining each step in the process. Then, have the students work either in groups or independently to solve the next word problem. Once you observed most of the students understanding of the concept, have them complete the worksheet and conduct small group instruction as needed.  At the conclusion of the lesson review answers to the worksheet and have students complete an exit to check for understanding. Upon review of all exit tickets, decide if most of the students have a sufficient knowledge base to formally assess.  For lesson five, review the concepts taught in this unit, so that the students are demonstrating the ability to apply the conceptual knowledge of the unit, administer the quiz/test.
