Why is Dr Loyd's Fraction Kit better than other products?
Beware of kits that label their pieces. Students who are taught to use symbolic representations like "¼" or "one-fourth" prior to developing a more fundamental conception of fractions through their visual understanding are at a disadvantage. They tend to approach fraction problems by trying to manipulate numbers and digits or by applying an abstract rule. his results in a diminished conceptual imprint of fractions (an imprint is the model students will later rely on when facing novel or challenging questions) which leaves the student with an inability to solve novel problems. Don't make the same mistake -- transparent, unmarked pieces enable fraction concepts to be developed independently of their symbolic representations.
Beware of using a circle or pie shape for instruction! Several websites and textbooks rely on circle diagrams as a visual representation for learning fractions by using familiar images such as cheese pizzas or apple pies. Although these objects are familiar, the shape of a circle is inferior for modeling fraction operations and will therefore serve as an inferior conceptual imprint for the student. Only rectangular pieces are able to accurately model all of the fraction operations, including how to name fractions and how to divide one fraction by another.
Fraction kits fashioned from household materials have several drawbacks. Instructions for making your own fraction kit out of construction paper and other household materials make it look like an easy an inexpensive alternative to acquiring a professional product. Although I am a DIY advocate and believe that making your own fraction kit is better than just working with a textbook, when it comes to a child's ability to learn fractions I am certain that $30 is well worth the price. Dr Loyd's Fraction Kit is made out of a color-tinted transparent plastic that facilitates instruction in ways that kits made out of construction paper cannot. First of all, as you could see in my video on common denominators, some of the fundamental fraction operations require transparent pieces in order to be visually modeled. Second, transparent pieces help students to further develop their concept of a fraction: because the pieces are transparent, students can place one piece on top of another while still seeing both of them: by seeing one piece within another piece, students come to literally come to see one piece as a fraction of the other piece.
Furthermore, it takes very little margin of error to make 3/4 look like 4/5 when pieces are cut by hand. Don't let students make that kind of mistaken equivalence. Dr Loyd's Fraction Kit contains durable plastic pieces that are cut to a twenty-thousandth of an inch tolerance. This ensures the precision required to keep all of your fractions distinct.
Finally, Dr Loyd's Fraction Kit also comes with a teacher's instruction manual which has been field-tested in countless workshops and classrooms. The manual is designed for instructors to teach students fractions with the fraction kit. It will walk instructors through time-tested and reliable ways to use the kit to name & rename fractions, find the least common denominator, & perform the addition of like, related and unrelated fractions; as well as model the subtraction, multiplication, and division of fractions.
