هل المثلثات العشوائية حادة أم منفرجة الزاوية؟

هل المثلثات العشوائية حادة أم منفرجة الزاوية؟

Rating

هذا الفيديو التعليمي يتعامل مع مسألة الاحتمالية الهندسية. الفكرة الرئيسية المعروضة هي حقيقة أن المعادلة الخطية للأبعاد الثلاثة تنتج الطائرة. يركز الفيديو على مثلثات عشوائية يتم تحديدها من خلال زواياها الثلاث الخاصة بها. يتم اختيار هذه الزوايا عشوائيا رهنا لحتمية وصول مجموعها الى 180 درجة. من الأمثلة على أنواع الأنشطة المتاحة داخل الصف أثناء فترة ما بين مقاطع الفيديو هي: اسأل ستة طلاب عن أرقام واجعل هذه الأرقام إحداثيات x,y لثلاث نقاط. ثم اطلب من الفصل محاولة معرفة كيفية تحديد ما إذا كان المثلث في تلك الزوايا حاد أو منفرج.

Figure This! Math Challenges for Families

Rating

This web site offers families, teachers, and tutors 80 mathematical challenges helpful for encouraging problem solving with students in grades 6 to 8. The math challenges focus on concepts and objects found in everyday life, such as how fast your heart beats, what shape container holds the most popcorn, and how much of me shows in a mirror. Each challenge contains an initial problem with a solution hint, a complete explanation of the answer, and additional problems related to the same challenge. Resources for further investigations are suggested as well. From the Printing the Challenges link on the homepage, PDF files are available for all 80 challenges in English, the first 15 challenges in Spanish, and the family resource materials in English and Spanish.

Statistical Analysis to Rank Baseball Players

Statistical Analysis to Rank Baseball Players

Rating

As Trudy DentonŐs statistics students assemble their baseball dream team, they must compare and analyze data for four Yankee players and then rank them in terms of their homerun data to fill the last spot on the team.Many factors go into determining which player is the greatest NY Yankee homerun hitter in history. Working in partners, students compare playerŐs data and must reconcile differences such as number of seasons and factors that impact performance. Using Fathom software, students are able to build stacked box plots and complete a comparative analysis of the data before ranking the players. There is a consensus about the top two players but students must defend and explain their choices for the remaining two players.This idea can be easily transferred to other statistical analysis and even modified to suit other grade levels, including middle school.
