Students will explore multi-digit numbers and the relationship between ones, tens and hundreds; a digit in one place is 10x the digit in the place to its right. Students will use their bodies to represent digits in multi-digit numbers up to the hundredths place and compare these numbers using <, =, >. Students will use their bodies as multi-digit numbers to add and subtract.

This lesson is about trying to get students to make connections between ideas about equations, inequalities, and expressions. The lesson is designed to give students opportunities to use mathematical vocabulary for a purpose to describe, discuss, and work with these symbol strings.The idea is for students to start gathering global information by looking at the whole number string rather than thinking only about individual procedures or steps. Hopefully students will begin to see the symbol strings as mathematical objects with their own unique set of attributes. (7th Grade Math)

Area and Perimeter
Conditions of Use:

This lesson is based on the results of a performance task in which we realized that students' understanding of area and perimeter was mostly procedural. Therefore the purpose of this re-engagement lesson was to address student misconceptions and deepen student understanding of area and perimeter. The standards addressed in this lesson involve finding perimeter and area of various shapes, finding the perimeter when given a fixed area, and using a formula in a practical context. Challenges for our students included decoding the language in the problem and proving their thinking. (7th Grade Math)

Daisy World Model
Conditions of Use:
Remix and Share

The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary environment. This site contains the online model of Daisy World for use in introductory courses as well as an assignment based on the model.

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.

Length Scales in the Solar System
Conditions of Use:
Remix and Share
Rating

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.

This wiki page list the activities, student projects and journal reflections from the Math Bootcamp July 6-9, 2010 in Portola Valley, CA. The Boot Camp is an intensive, one-week program focused on accelerating the learning of some of the San Francisco Peninsula’s high potential young minds. It is directed at rising 6 -12th graders (we will be willing to make exceptions for particularly mature rising 5th graders) who demonstrate the motivation and ability to deepen their understanding of math, science and engineering. Although this is not an SAT-prep course, SAT-type problems will be heavily used and the students will be encouraged to take the SAT to assess their overall progress. The heavy thinking will be interspersed with creative and physical activities to ensure the flow of blood to both the body and brain!

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.

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)

فهم العلوم: كيف تعمل العلوم فعلاً
Rating

إن رسالة "فهم العلوم" هو أن يقدم مورد ممتع وسهل الوصول ومجاني يعمل على التعريف الدقيق بماهية العلوم وكيفية عملها فعلاً. إن المنهج العلمي شيق، إلا أن الشروحات القياسية غالباً ما تغفل عن الطبيعة الديناميكية للعلوم. وتؤثر العلوم فينا جميعاً كل يوم، لكن كثيراً ما يشعر الناس بأنهم منعزلون عن العلوم. إن العلوم هي مسعى إنساني مكثف، إلا أن العديد من التصويرات تخفي جوانب الشغف والفضول، بل وحتى المنافسات والمكائد، التي تميز كل المشروعات الإنسانية. يقدم "فهم العلوم" للمستخدمين نظرة من الداخل على المبادئ العامة والمناهج والمحفزات التي تندرج في كل العلوم. يتضمن هذا المشروع في رحمه محاولة لإعادة الاندماج مع العلوم، والتي تبدأ بإعداد المعلم وتنتهي بالفهم العام الأوسع للعلوم. وتضم الأهداف العاجلة للمشروع: (1) تحسين فهم المعلم لطبيعة العمل العلمي، (2) توفير الموارد والاستراتيجيات التي تشجع معلمي الصفوف من الحضانة وحتى السادس عشر على تدعيم طبيعة العلوم طوال ممارستهم لتدريس العلوم، (3) توفير مرجع واضح وغزير للطلاب وعموم الناس، والذي يصور المسعى العلمي بدقة. لقد جرى إنشاء موقع "فهم العلوم" بواسطة متحف متحجرات جامعة كاليفورنيا بمدينة بيركلي، وذلك بالتعاون مع مجموعة متنوعة من العلماء والمعلمين، وتم تمويله بواسطة المؤسسة الوطنية للعلوم1. علماً بأن "فهم العلوم" كان قد استلهم واستوحى فكرته في البداية من عملنا المتعلق بمشروع "فهم التطور" الذي أبرز حقيقة أن العديد من المفاهيم المغلوطة حول التطور تنبع من سوء فهم طبيعة العلوم. فضلاً عن ذلك، يشير البحث إلى أن الطلاب والمعلمين في كل المستويات الدراسية لديهم فهم منقوص لطبيعة ومنهج العلوم، الأمر الذي يمكن أن نعزوه إلى الفصول المدرسية حيث يتم فيها تدريس العلوم بوصفها عملية بسيطة وخطية ولا تتولد عنها أشياء. وهذا التصوير الكاذب والمُقفِر يجعل الطلاب ينفصلون عن العلوم، ويثبط الدعم العام لها، وربما يساعد على تفسير المؤشرات الحالية بأن الولايات المتحدة تفقد ثقلها العالمي في مجال العلوم. فحتى وأبعد من الاهتمام بصحة الاقتصاد الأميركي، فإن عامة الناس بداخلهم احتياج أصيل للتقييم النقدي للطروحات المتضاربة للدليل العلمي في وسائل الإعلام. ولكي يفعلوا هذا، عليهم فهم مواطن القوة والقيود والمناهج الأساسية للمشروع الذي أنتج تلك الادعاءات العلمية. يقوم "فهم العلوم" بخطوة هامة نحو الوفاء بهذه الاحتياجات.
