A-CED Regular Tessellations of the plane
Unrestricted Use
CC BY
Rating

This task examines the ways in which the plane can be covered by regular polygons in a very strict arrangement called a regular tessellation. These tessellations are studied here using algebra, which enters the picture via the formula for the measure of the interior angles of a regular polygon (which should therefore be introduced or reviewed before beginning the task). The goal of the task is to use algebra in order to understand which tessellations of the plane with regular polygons are possible.

المعادلات والمتباينات والمقادير الجبرية
قراءة النص المطبوع بخط رفيع
Rating

يدور هذا الدرس حول محاولة جعل الطلاب يقيمون روابط بين الأفكار عن المعادلات والمتباينات والمقادير الجبرية. علماً بأن الدرس مصمم ليمنح الطلاب فرص استخدام المفردات الرياضية لغرض الوصف والمناقشة والعمل مع سلاسل الرموز هذه. وتهدف الفكرة إلى بدء الطلاب في تحصيل المعلومة الشاملة بالنظر إلى كامل سلسلة الأعداد بدلاً من التفكير فقط في إجراءات أو خطوات فردية. ومن المأمول أن يبدأ الطلاب في رؤية سلاسل الرموز كأغراض رياضية لها مجموعتها الفريدة من الصفات الخاصة بها.

الغرض من هذا الفيديو التعليمي هو أن يرى الطلاب كيفية التفكير بتحرر أكبر حول مسائل الرياضيات والعلوم. فأحياناً يكون الحصول على إجابة تقريبية في مدة زمنية أقصر بكثير هو أمر يستحق الوقت الذي تم ادخاره. ويستكشف هذا الفيديو آليات لعمل حسابات تقريبية سريعة وارتجالية، وليست فقط دقيقة على نحو مدهش وإنما أيضاً منيرة لبناء الحدس والبديهة في فهم العلوم. ويتطرق هذا الفيديو إلى الجبر 1 الخاص بالصف العاشر وكذلك إلى فيزياء أولى ثانوي، إلا أن المفاهيم التي يغطيها (السرعة، المسافة، الكتلة، إلخ) أساسية بشكل كافي ليفهمها الطلاب الأصغر سناً الذين لديهم معرفة بالعلوم. وفي حالة الرغبة، يمكن للمعلمين أن يحضروا بندولات ذات أطوال مختلفة، وأثقال للتعليق، وساعة مؤقت لقياس المدة الزمنية. ومن الأمثلة على أنواع التمارين داخل الفصل المدرسي خلال الفترات الفاصلة بين مقاطع الفيديو، أن: تطلب من الطلاب تقدير حاصل ضرب 29 x 31 دون آلة حاسبة أو ورقة وقلم؛ وكذلك تسأل الطلاب عن المقدار الذي يستطيعون فيه الاقتراب من الثقب الأسود دون أن يبتلعهم.

This lesson is about properties of quadrilaterals and learning to investigate, formulate, conjecture, justify, and ultimately prove mathematical theorems. Students will: Analyze characteristics and properties of two- and three-dimensional geometric shapes; develop mathematical arguments about geometric relationships; and apply appropriate techniques, tools, and formulas to determine measurements.Explore relationships among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them. Employ forms of mathematical reasoning and proof appropriate to the solution of the problem at hand, including deductive and inductive reasoning, making and testing conjectures, and using counter examples and indirect proof. Identify, formulate and confirm conjectures. Establish the validity of geometric conjectures using deduction, prove theorems, and critique arguments made by others. (9th/10th Grade Math)
