سيقوم الطلاب باكتشاف أعداد مكونة من أرقام متعددة والعلاقة بين الأحاد، العشرات والمئات؛ ان رقما في مكان واحد هو 10X الرقم في المكان الأيمن له. سيقوم الطلاب باستخدام أجسادهم لتمثيل الأعداد المكونة من أرقام متعددة وصولا إلى مكان المئات ومقارنة هذه الأرقام باستخدام <، =،>. سيقوم الطلاب باستخدام أجسادهم والأعداد المكونة من أرقام متعددة للجمع والطرح.
يوضح هذا العرض التوضيحي مفهوم دوران مضلع ثنائي الأبعاد. مصفوفة الدوران للزاوية الحالية معروضة أمامنا. المضلع الافتراضي هو مربع يمكنك تعديله.
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.

يستند هذا الدرس على نتائج مهمة الأداء الذي أدركنا منه أن فهم الطلاب للمساحة والمحيط كانت معظمها إجرائية. لذلك كان الغرض من هذا الدرس إعادة الانخراط لمعالجة المفاهيم الخاطئة لدى الطالب وتعميق فهم الطلاب للمساحة والمحيط. ان المعايير التي تم تناولها في هذا الدرس تنطوي على إيجاد محيط ومساحة الأشكال المختلفة، وإيجاد المحيط عند إعطاء مساحة ثابتة، واستخدام الصيغة في سياق عملي. وشملت التحديات التي تواجه طلابنا فك رموز اللغة في المشكلة واثبات طريقة تفكيرهم.

The foundation of this lesson is constructing, communicating, and evaluating student-generated tables while making comparisons between three different financial plans. Students are given three different DVD rental plans and asked to analyze each one to see if they could determine when the 3 different DVD plans cost the same amount of money, if ever.

This page documents ISKME’s 2013-2014 Open Educational Resources (OER) Fellowship Program which mentors educational leaders to champion OER into classrooms, school districts, and communities. The program runs from September until October and includes eight math teachers from Doha, Qatar.
If two inscribed angles intercept the same arc, then the angles are equal. Drag the orange points to change the figure.
In this packet we look at works that span nearly a thousand yearsäóîfrom shortly after the foundation of Islam in the seventh century to the seventeenth century when the last two great Islamic empiresäóîthe Ottoman and the Safavidäóîhad reached their peak. Although the definition of Islamic art usually includes work made in Mughal India, it is beyond the scope of this packet. The works we will look at here come from as far west as Spain and as far east as Afghanistan.
A dynamically simplified solar system is constructed from online data to explore the real solar system on many different scales.
The realistically scaled solar system is surprising because nothing is visible due to the presence of many different scales. That is why it is usually rescaled in animations or illustrations. This is nice but gives us a wrong sense of distances and sizes. This Demonstration is intended to show the solar system's different scales in their full glory.
Since it is hardly possible to see anything when the real scales are used, controls have been added to modify the sizes of the celestial bodies.
Students will explore the mathematics behind mandalas, including but not limited to shapes and symmetry.
A collaboration between the National Aeronautics and Space Administration (NASA) and the CK-12 Foundation, this book provides high school mathematics and physics teachers with an introduction to the main principles of modeling and simulation used in science and engineering. An appendix of lesson plans is included.
This lesson is a re-engagement lesson designed for learners to revisit a problem-solving task they have already experienced. Students will activate prior knowledge of graphical representations through the 'what's my rule' number talk; compare and contrast two different learners' interpretations of the growing pattern; use multiple representations to demonstrate how one of these learners would represent the numeric pattern; make connections between the different representations to more critically compare the two interpretations.

The goals of the International OER Exchange Pilot project are to: facilitate the development and use of Open Educational Resources (OER) by teachers and students globally, track the development and use of the science learning materials and data collection, especially around climate change study, created in the project through OER Commons, and highlight the process and results through workshops and conference presentations.The broader purpose of the project is to support the international exchange of information and understanding through freely available resources among teachers and students, especially in the area of environmental science and climate change investigation.
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)
This lesson is about ratios and proportions using candy boxes as well as a recipe for making candy as situations to be considered. It addresses many Mathematical Reasoning standards and asks students to: Use models to understand fractions and to solve ratio problems; think about a ratio as part/part model and to think about the pattern growing in equal groups or a unit composed of the sum of the parts; find a scale factor and apply it to a ratio. (5th Grade Math)
This lesson focuses on students making decisions about what tools to apply to solve different problems related to quadratic expressions and equations. It is also intended to build awareness of the form an answer will take in order to help students make sense of the kind of problem they are solving. (9th/10th/11th Grade Math)
Educators are provided with guiding questions around which concepts and skills to consider when developing curriculum, as well as which options will provide the greatest accessibility for student success.
