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)

ان الغرض من هذا الفيديو التعليمي هو إظهار الطلاب لكيفية التفكير بحرية أكبر حول مشاكل الرياضيات والعلوم. ان الحصول في بعض الأحيان على إجابة تقريبية في فترة أقصرهو أمر يستحق الوقت الموفر. يستكشف هذا الفيديو تقنيات لصنع خلفيات تقريبية سريعة للمغلف الذي ليس فقط مستغرب من جهة الدقة، ولكنه أيضا منيرا لبناء الحدس في فهم العلم. يقترب هذا الفيديو من مستوى الصف العاشرالخاص بالجبر 1 ومن مستوى الفيزياء للعام الأول الثانوي، ولكن المفاهيم المتضمنة به (السرعة، المسافة، الكتلة، إلخ) هي أساسية بما يكفي لأن يستوعبها طلاب العلوم الأصغر سنا. إذا رغبت، بامكان المدرسين جلب بندول الساعة من مختلف الأطوال , الأوزان لتعليقه, و ساعة وقت لقياس الفترة. تتضمن الأمثلة على التمارين التي تمارس في الفصل فيما بين مقاطع الفيديو: سؤال الطلاب لتقدير 29 × 31 دون آلة حاسبة أو ورقة وقلم رصاص؛ وسؤال الطلاب عن ما مدى امكانية وصولهم الى الثقب الأسود بدون الانزلاق بداخله.
This lesson unit is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who: use inappropriate additive strategies in scaling problems, which have a multiplicative structure; rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition, and have not developed a single multiplier strategy for solving proportionality problems; and see multiplication as making numbers bigger, and division as making numbers smaller.
This learning video presents an introduction to the Flaws of Averages using three exciting examples: the ''crossing of the river'' example, the ''cookie'' example, and the ''dance class'' example. Averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, however, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. During this video lesson, students will learn about three flaws of averages: (1) The average is not always a good description of the actual situation, (2) The function of the average is not always the same as the average of the function, and (3) The average depends on your perspective. To convey these concepts, the students are presented with the three real world examples mentioned above.
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.

These data analysis problems of the month are designed to be used schoolwide to promote a problem-solving theme at your school. Each problem is divided into five levels, Level A through Level E, to allow access and scaffolding for the students into different aspects of the problem and to stretch students to go deeper into mathematical complexity. The problems cover statistics, probability, discrete math, and counting principles.

This online math course develops the mathematics needed to formulate and analyze probability models for idealized situations drawn from everyday life. Topics include elementary set theory, techniques for systematic counting, axioms for probability, conditional probability, discrete random variables, infinite geometric series, and random walks. Applications to card games like bridge and poker, to gambling, to sports, to election results, and to inference in fields like history and genealogy, national security, and theology. The emphasis is on careful application of basic principles rather than on memorizing and using formulas.
This lesson unit is intended to help teachers assess how well students are able to understand and use directed numbers in context. It is intended to help identify and aid students who have difficulties in ordering, comparing, adding, and subtracting positive and negative integers. Particular attention is paid to the use of negative numbers on number lines to explore the structures: starting temperature + change in temperature = final temperature final temperature Đ change in temperature = starting temperature final temperature Đ starting temperature = change in temperature.
