Part A: Content Goals for Measurement in Grades 3-5
Most students enter grade 3 with enthusiasm for, and interest in, learning mathematics. In fact, nearly three-quarters of U.S. fourth graders report liking mathematics (NCTM, 143). This can be a very critical time in keeping children interested in what they are learning. If the work turns too monotonous and uninteresting it can have a negative effect on their perceptions of the subject later in life. If students in grades three through five are given mathematic material that is interesting it can help keep their enthusiasm toward the subject. One of the major content areas that is covered at this time is measurement. Measurement is one of the ways that teachers can introduce students to the usefulness and practicality of mathematics. Measurement requires the comparison of an attribute (distance, surface, capacity, mass, time, temperature) between two objects or to a known standard. Measurement also introduces students to the important concepts of precision, approximation, tolerance, error and dimension. Instructional programs from prekindergarten through grade twelve should enable students to understand measurable attributes of objects and the units, systems, and processes of measurement. Also, apply the appropriate techniques, tools, and formulas to determine measurements (NCTM, 171). This paper will describe how those ideas are developed in grades three through five.
The first and most basic standard for measurement at this level is being able to understand measurement attributes that we use on a daily basis. Some of these attributes include length, area, weight, volume, and size of an angle. Knowledge of these variables is very important because they are ideas that will be used regularly throughout their lives. When students attain a better understanding of these measurement variables the next objective is to have them decipher the correct way to measure them. Choosing the appropriate unit to measure variables such as length, area, and weight can be just as important as knowing their meaning. For example, knowing that length is the distance between two points is irrelevant if a student tries to measure it with an angle or area. Knowing the proper way to measure a variable is very important. This idea also brings into perspective the standard of measurement that deals with understanding the need for standard units, or a basic way to describe an attribute. This requires students to become familiar with standard units in the customary and metric systems.
... measure. They will not want the hassle of remembering two different measurements throughout their lives. Americans are not very stubborn and are willing enough to change to a simpler system of measurements.
Place value and the base ten number system are two extremely important areas in mathematics. Without an in-depth understanding of these areas students may struggle in later mathematics. Using an effective diagnostic assessment, such as the place value assessment interview, teachers are able to highlight students understanding and misconceptions. By highlighting these areas teachers can form a plan using the many effective tasks and resources available to build a more robust understanding. A one-on-one session with Joe, a Year 5 student, was conducted with the place value assessment interview. From the outlined areas of understanding and misconception a serious of six tutorial lessons were planned. The lessons were designed using
To supplement the lesson place value worksheets were given out for the students work on at home. Over the course of three days the concept was reviewed at the begging of math class before introducing similar concepts such as adding thousands and ten thousands to the place value work sheets. At the end of the unit the students were given a test that covered

Mathematics education has undergone many changes over the last several years. Some of these changes include the key concepts all students must master and how they are taught. According to Jacob Vigdor, the concerns about students’ math achievements have always been apparent. A few reasons that are negatively impacting the productivity of students’ math achievements are historical events that influenced mathematics, how math is being taught, and differentiation of curriculum.
As you explained in your post teaching measurement unit in Preschool is hands on and play way.

Mathematical dialogue within the classroom has been argued to be effective and a ‘necessary’ tool for children’s development in terms of errors and misconceptions. It has been mentioned how dialogue can broaden the children’s perception of the topic, provides useful opportunities to develop meaningful understandings and proves a good assessment tool. The NNS (1999) states that better numeracy standards occur when children are expected to use correct mathematical vocabulary and explain mathematical ideas. In addition to this, teachers are expected

Students will identify the correct how to find the area of circles. We are going to do this first by deriving the formula for the area of a circle ourselves. Students use these operations to solve problems. Students extend their previous understandings of finding the area of a shape: This learning goal meets the Common Core Standard CCSS.MATH.CONTENT.6.G.A.3. The students are going to learn find the area of only the doughnut, excluding the hole in the middle. For the formative assessments during the teaching of this unit, I will keep an observation log, where I note any student progress, whether it be positive or negative. I believe it will be important to record observations any time a student has difficulty with a particular task. For example, if a student has trouble solving the problems with the formulas. to purchase an item, I should write down particular actions, attitudes, and behaviors that stand out, as well as the specific issue. Any time the students are doing independent work, I will monitor the learning activities and record observations.

The early acquisition of mathematical concepts in children is essential for their overall cognitive development. It is imperative that educators focus on theoretical views to guide and plan the development of mathematical concepts in the early years. Early math concepts involve learning skills such as matching, ordering, sorting, classifying, sequencing and patterning. The early environment offers the foundation for children to develop an interest in numbers and their concepts. Children develop and construct their own meaning of numbers through active learning rather than teacher directed instruction.
