Fractions Fractions are difficult to learn and to teach, however they form an important part of primary education mathematics. Fractions both underpin the development of proportional reasoning, including the understanding of algebra and probability. Much of the confusion of teaching and learning fractions appear to be from the many different coding conventions (6/5, 1 1/4, 1.25, 125%), different representations (models) and interpretations (constructs) (Clarke, Roche & Mitchell, 2008). The problem for students is how to make all these connections so they can obtain a mature and flexible understanding of fractions. Another problem is that the educators are not equipped with the experience and knowledge of teaching fractions effectively. When…
In preparation for fractions number talk what I observed was very beneficial for students at the carpet it allowed students to discuss and share with one another. I liked the fact that after a student share students had to give a particular cue saying if they agreed with peer. I thought that was awesome. I also like how she went over what to expect during learning at table and how students will share. So some type of feedback was to be expected even if student did not still quite understand. As…
disadvantages. Four classic manipulatives used in today’s classrooms are: fraction strips, base ten blocks, counters, and pattern blocks. Fraction strips are a manipulative designed to represent and compare fractions. They are rectangular pieces of plastic, foam, or paper which represent different parts of a whole. They are various sizes and colors based on their denominators, and can be used to help students visualize explore the concepts of fraction equivalency, adding and subtracting…
For this curriculum study, I chose third grade mathematics as my unit of study. As far as my objectives go, I would want my students to walk away from this particular section of fractions with the understanding of what a fraction is, the difference between the components of a fraction such as the numerator and denominator, knowing how to identify how many parts of a whole are shaded in, and knowing how to simplify a fraction. As far as my instructional method, I created an original prezi, which…
As you begin to insert your responses to the prompts found in this document, please be sure to save it frequently, (and note the location of the file) so as to not lose any of your work. Once completed, you will submit this document to WGU for grading. Instruct What student misconceptions have you encountered related to fraction, decimal, and percentage concepts? How do you help students understand the notion of equivalence among fractions or prepare them for this understanding? One…
Students learn fractions much earlier than the average person expects. In today’s American education system, children are officially introduced to fractions in first grade. Children use fractions frequently in everyday life and in academics too. A website called, “Math Warehouse Lesson Plans,” provides a lesson plan about teaching fractions to first graders. This lesson plan can easily relate to an article written by the National Counsel of Teachers called, “Common Core brief: The fraction…
Fractions are a difficult and often miss understood by many students, they deviate from normal structure of numbers and as suggested by Gould (2013) students struggle to comprehend the changed symbols that are used with fraction. Students also struggle to grasp that all fractions are part of a whole; this is a direct relation to understanding the set up and structure of a fractions. Students can often become confused by the language that teacher use when describing fractions. Many teachers…
Trastuzumab is found to inhibit the Her2 expression ultimately inhibiting the malignant transformation of the cancer cells working at the DNA level preventing cancer cell growth and proliferation. At the same time, this is detrimental to the myocardium as ErbB2 signaling has a vital role of maintaining left ventricular function. This chemotherapy agent is believed to inhibit the ErbB2 for Her2-positive breast cancer tumors while also inhibiting the cardiac signaling ultimately leading to heart…

the 2013 estimated total cost of $32 billion.2 HF incidence increases with age, rising from approximately 20 per 1000 individuals 65 to 69 years of age to >80 per 1000 individuals 65 to 69 years of age.1 Blacks have the highest risk for HF. In the ARIC (Atherosclerosis Risk in Communities) study, incidence rate per 1000 person-years was lowest among white women and highest among black men.1 HF may result from disorders of myocardium, pericardium, endocardium, and heart valves or from certain…
