Problems of the Month Problem solving is the cornerstone of doing mathematics. A problem that you can’t solve in less than a day is usually a problem that is similar to one that you have solved before. But in real life, a problem is a situation that confronts you and you don’t have an idea of where to even start. If we want our students to be problem solvers and mathematically powerful, we must model perseverance and challenge students with non-routine problems. Administrators, teachers and parents should facilitate and support students in the process of attacking and reasoning about the problems. The solution is not as important as the process of problem solving. The educator or parent should not be impatient with the student’s struggle. The principal should embrace the concept of problem solving and model problem-solving leadership, being a facilitator of non-routine problems. Once the problem is presented to the students, the principal should be visible in facilitating the tasks alongside the teachers.

Area Formulas In this lesson, students will use the area formula for rectangles to discover the area formula for parallelograms. As necessary, review the concept of area as well as the area formula, A = bh. It may also be beneficial to review the properties of parallelograms as they relate to other quadrilaterals. To begin the lesson, have students look at a U.S. map. Distribute the Rectangles and Parallelograms and the Quadrilateral Area Record activity sheets. For each rectangle, students can simply count the number of squares, or they can multiply the length by the width. Then, have student cut out shapes A, B, and C. With rectangle A, have students cut from the lower left corner to a point on the top edgt that is three units in from the upper left vertex; this cut will form a 45-degree angle, which divides each of the squares through which it passes exactly in half. Students should then determine the area of the resulting parallelograms and record the results on the record sheet. 1. 2. 3. 4.

La découverte d'une "tuile" historique secoue le monde des mathématiques SCIENCES - Une équipe de mathématiciens a bouleversé le monde des maths en découvrant un nouveau type de pentagone capable de "paver un plan", c'est-à-dire que les tuiles peuvent s'assembler sur une surface plane sans qu'elles ne se chevauchent ni ne laissent de trous. Seuls quinze pentagones de ce type ont été découverts jusqu'ici. On n'en avait pas découvert depuis trente ans. C'est presque aussi impressionnant que de découvrir un nouvel atome, a déclaré Dr. Casey Mann, maître de conférences en mathématiques à l'université de Washington Bothell et membre de l'équipe. L'équipe a fait cette découverte grâce à un programme informatique conçu pour l'occasion. "Nous avons découvert la tuile en faisant une recherche exhaustive sur un ordinateur grâce à un ensemble de possibilités très large mais fini", a expliqué Casey Mann au journal Le Guardian, en ajoutant que l'équipe avait été "un peu surprise" de découvrir un nouveau type de pentagone.

I Love Maths Games The Game of SKUNK Write the following questions on the chalkboard or overhead: I might make more money if I was in business for myself; should I quit my job? An earthquake might destroy my house; should I buy insurance? My mathematics teacher might collect homework today; should I do it? Ask students to share their responses to each of these scenarios. Every day each of us must make choices like those described above. Making the connection between choice and chance is basic to understanding the significance and usefulness of mathematical probability. The game of SKUNK presents middle-grade students with an experience that clearly involves both choice and chance. The Game of SKUNK To start the game each player makes a score sheet like this: Each letter of SKUNK represents a different round of the game; play begins with the "S" column and continue through the "K" column. At the beginning of each round, every player stands. Playing SKUNK with the Whole Class SKUNK Further Examples Sheet Thinking about SKUNK
