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.

AAS Congruent Triangles
Conditions of Use:

Rating

An interactive applet and associated web page that shows how triangles that have two angles and a non-included side the same must be congruent. The applet shows two triangles, one of which can be reshaped by dragging any vertex. The other changes to remain congruent to it and the two angles and non-included side are outlined in bold to show they are the same measure and are the elements being used to prove congruence. The web page describes all this and has links to other related pages. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

A-CED Regular Tessellations of the plane
Conditions of Use:
No Strings Attached
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.

Algebraic Equations, Inequalities, and Properties
Conditions of Use:

Rating

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)

Angle Hunting
Conditions of Use:

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment. Learners will observe that angle measurements do not change with distance, because they are distance invariant, or constant. Note: The "Pocket Protractor" activity should be done ahead as a separate activity (see related resource), but a standard protractor can be used as a substitute.

Are Random Triangles Acute or Obtuse?
Conditions of Use:
Remix and Share
Rating

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.

Area and Perimeter
Conditions of Use:

Rating

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)

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.

The Art of Approximation in Science and Engineering: How to Whip Out Answers Quickly
Conditions of Use:
Remix and Share
Rating

The purpose of this learning video is to show students how to think more freely about math and science problems. Sometimes getting an approximate answer in a much shorter period of time is well worth the time saved. This video explores techniques for making quick, back-of-the-envelope approximations that are not only surprisingly accurate, but are also illuminating for building intuition in understanding science. This video touches upon 10th-grade level Algebra I and first-year high school physics, but the concepts covered (velocity, distance, mass, etc) are basic enough that science-oriented younger students would understand. If desired, teachers may bring in pendula of various lengths, weights to hang, and a stopwatch to measure period. Examples of in- class exercises for between the video segments include: asking students to estimate 29 x 31 without a calculator or paper and pencil; and asking students how close they can get to a black hole without getting sucked in.

This course serves as an introduction to the pre-modern Islamic artistic traditions of the Mediterranean, Near East, and Central and South Asia. It surveys core Islamic beliefs, the basic characteristics of Islamic art and architecture, and art and architecture created under each dynasty and ruling party. Upon successful completion of this course, the student will be able to: identify the core beliefs of Islam, the major characteristics of Islamic art, and the major forms of Islamic architecture; identify major pre-modern Islamic works of art and monuments from the Middle East, Northern Africa, Spain, and South Asia; explain how the core beliefs of Islam contributed to the basic characteristics of Islamic art and architecture and the secular art works and architecture of the Islamic world; identify the succeeding dynasties that ruled the Islamic world; explain the important role that the patronage of art and architecture had played in definitions of kingship.

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying. When we tried this trick on the Exploratorium's exhibit floor, we gathered a crowd of visitors who wanted to know what we were doing. We explained that we were engaged in serious scientific experimentation related to energy transfer. Some of them may have believed us. If you'd like to go into the physical calculations of this phenomenam, see the related resource "Bouncing Balls" - it's the same activity but with the math explained.
