The methodology was qualitative. As the teacher/researcher, I assumed a dual role in the classroom: an unobtrusive observer of small group work and a facilitator of whole group discussions. Throughout the project, I used audio- and video recordings to capture the participants" starts, stops, and ultimate success as they untangled various concepts. Other data include the participants" pre-task and post-task journal entries, survey and interviews, observation notes and field notes.The purpose of this investigation was to construct a conceptual tool to assist teachers in the understanding and teaching of division with fractions. To that end, this research investigated the concepts underpinning a robust comprehension of this domain. Also investigated were the processes one group of students used to determine those concepts. The participants were seven prospective elementary teachers enrolled in my math methods course, and me, the teacher/researcher. The study records, in our voices, the concepts and processes the participants constructed as they gained conceptual knowledge of division with fractions.This study provides an in-depth analysis of six interpretations for division with fractions: three interpretations found in the literature, a third briefly mentioned in the literature, two interpretations from my prior research in the field, and one additional interpretation that emerged from the study. I created a conceptual taxonomy to highlight common meanings across interpretations and to distinguish intrinsic differences among interpretations. In addition to the taxonomy, terms found in the literature are articulated, expanded, and applied to the learning process. Some terms not found in the literature, or found to be vague, were constructed to help the participants better communicate implicit understandings. Rich vignettes, diagrams, and authentic word problems report participants" interactions, capturing in detail how their knowledge developed. As a result, these findings may serve as a tool for teachers: a tool to discern the misconceptions of struggling students, to use when planning instruction, and a tool to further both their own learning and the learning of their students.

The Book of Fractions The graphical representation of a fraction 6 F Draw a diagram to show each fraction (use the images on the bottom of this page): 1. A fraction represents a part of a whole. Example 1. The whole is divided into four equal parts. Three part are taken (considered).

A corresponding graphical representation (diagram) is File Size: KB. devoid of context, you cannot determine which interpretation of the fraction is intended.

The various interpretations are needed, however, in order to make sense of fraction problems and situations. Fractions as parts of wholes or part of sets.

One meaning of fraction is as a part of a Size: KB. Division with Unit Fractions will help students practice this key fifth grade skill. See in a Guided Lesson. Grade. 5th grade.

6 Example 4 Find 8 ÷ 2 1 —. (answer key) 6. The numerator (8) is less than the denominator (9), so this fraction is a proper fraction. The numerator (20) is less than the denominator (23), so this fraction is a proper fraction.

The numerator (75) is greater than the denominator (51), so this fraction is an improper fraction. Rewrite each of the following fractions as a whole number. Measurement Interpretation and How it Relates to Division of Fractions: Savannah has 1/2 yard of fabric to make placemats for her dining room table.

e.g. 10 = 1 10 3. Mixed Numbers A mixed number is a combination of a whole number and a common fraction. e.g. 2 5 3 (two and three-fifths) 27 9 2 (twenty-seven and two-ninths) 9 6 3 = 9 2 1 (always.

For example, create a story context for (2/3) ÷ (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) ÷.

So another way of thinking about it is that 8/3 divided by 1/3 is the same thing as 8/3 times 3. And we could either write it like this. We could write times 3 like that. Or, if we want to write 3 as a fraction, we know that 3 is the same thing as 3/1. And we already know how to multiply fractions.

Multiply the numerators. 8 times 3. Fractions as Division CCSS Math NFB.3 asks students to interpret fractions as division of the numerator by the denominator. This activity helps students to work with that idea.

Fractions as division Anyone who has studied secondary school mathematics would probably be comfortable with the convention of ' a over b ' meaning ' a divided by b '.

That is, $$\frac{a}{b}$$ = a ÷ b. The fraction symbol here can be interpreted as division. And looking at this diagram right here, it made complete sense. If you started with 3 wholes, and you want to divide it into 4 equal groups, one group, two groups, three groups, four groups, each group is going to have 3/4 in it.

The most sophisticated part of the study of fractions occurs naturally in grades 6 and 7, where the concept of fraction division is fully explained. Division is the foundation on which the concepts of percent, ratio, and rate are built. Needless to say, it is the latter concepts that play a dominant role in applications.

The discus. Fractions domain, to multiply and divide fractions. Key developments in grade 5 include connecting fractions to division (B.3), multiplying a whole number or a fraction by a fraction (B.4), and understanding multiplication as scaling (B.5) in preparation for ratios and proportional relationships, which is introduced in grade 6.Fractions are divisions (5th grade math) We study the concept that a whole-number division problem, such as 21 ÷ 5, can be solved by writing it as a fraction.

In other words, the answer to 21 ÷ 5 IS the fraction 21/5. I justify that by solving a few division problems with the help of a visual model.Section 2.
