Comment multiplier et diviser des fractions ?
Pour diviser une fraction par une fraction on la multiplie par la fraction inverse. Et pour multiplier deux fractions on multiplie les numérateurs entre eux et les dénominateurs entre eux.- Les multiplications et divisions sont effectuées de gauche à droite: Si une multiplication est à gauche d'une division, on effectue d'abord la multiplication. Si une division est à gauche d'une multiplication, on effectue d'abord la division.

Participants in the study, students who had been taught with P&$1P, |POWNCFTUPD'-&, L during kindergarten, first, and second grade, were in three different second grade classes at a suburban public school. Classes were sorted by gender (to balance the number of girls and boys) and not by ability. The school adhered to the Core Curriculum State Standards (2011) in mathematics. The new mate rials r eplaced materials from the district cur- riculum F|&d!+!'&NBVIGcovering numbers and numeric relations. The district curriculum was used for topics (e.g., graphs, measurements) outside the scope of the new curriculum. Daily mathematics lessons lasted for an hour. Teachers were required to use P&$1P, |POWNCFTU D'-&, LP for a minimum of fifteen minutes. Rprbckpo
There were 8 female and 16 male student
s. Of these, 8 we re Hispanic, 8 were White, 3 were African-American, 3 were multi-racial, and 2 were Asian. Nine students
qualified for free or reduced fee lunch. All were profi- cient in English and 6 were bi-lingual, speaking a lan-guage other than English at home. Mean age at the time
of post-testing was 8 years, 2 months (98 months); range was 7 years, 8 months (92 months) to 8 years, 7 months (103 m onths). Sc Wafcno
Two classes had the same teachers for the entire school year. One teacher had four years" experience teaching second grade; the other had nine years" experience teach- ing both second and third grades. The third class had two teachers. The first, who went on leave at the end of December, taught for 23 years. She had experience with kindergarten, first, second and fifth grade classes. The s econd was a substitute who taught at the school for t hree years. She was the only teacher with prior experi- ence using the intervention (in kindergarten and first grade).

The chart is shown in Figure 3. There are several things to notice about the format. First, the upper left cell con- tains symbols for multiplication and division. Second, each column begins with the square of its number. For example, the twos column begins with 4 (2 x 2 = 4). This is because 2 (1 x 2 = 2) is included in the ones column. 06yE©eNeE& ulR
