"It  is good when pupil who got help today - will help to smbd tomorrow. Only in this case there is no  one  who is  superior. The secret of the success  in  math  is  attention  to  the …"

Michael Friedberg replied to Rashmi Kathuria's discussion Greatest challenge as a Math teacher ???
"It is surprising! Almost every man will tell You he is not good in math. So where are all engineers, researchers, scientists from? Ask "usual" man - has he a friend scientist, engineer or good math teacher? Maybe professional math users…"

"in the right - angled triangle the height dropped onto hypotenuse is the geometric mean between the segments of the hypotenuse which are created . The students must reveal this fact during learning the similarity in triangles - without any struggle,…"

Michael Friedberg replied to Rashmi Kathuria's discussion Common errors in Mathematics
"Surely I agree with Mrs Carolyne Melo - and me also do the same. But I also can see that the origin of these mistakes is in the way of learning - not in pupils. But what a nuisance it is that pupils are subject to double standard of math culture.…"

Michael Friedberg replied to Rashmi Kathuria's discussion Greatest challenge as a Math teacher ???
"The challenge of teaching math is, IMHO, to study it in order to use it. Exactly as every craft. In "our" time, that is in 50-s 60-s we didn`t think about our attitude to math - we simple learned it. Modern habit of continuous self -…"

Michael Friedberg replied to Rashmi Kathuria's discussion How to introduce coordinate geometry? in the group Introducing Math Concepts
"We had a little discussion about one graphic solution of trigonometric problem ( see my comment and attachment ) - with a lot good sense of humor - since it wasn`t an introductory level. And now about introductions... Many times while presenting to…"

Michael Friedberg replied to Rashmi Kathuria's discussion How to introduce coordinate geometry? in the group Introducing Math Concepts
"Surely not. It`s an example of building right angle NOT from the grid lines? and there is congruence of right-angle triangles. This example grows up on advanced steps of coordinate method, and it may illustrate the well - known formulas for slopes…"

Michael Friedberg replied to Rashmi Kathuria's discussion How to introduce coordinate geometry? in the group Introducing Math Concepts
"My experience of teaching the coordinate geometry is to begin it when children already know the connection between the position of point and it`s coordinates. It is necessary that they will know about locus ( maybe intuitively ) - from euclidian…"

Introducing Math Concepts

The objective of setting this group is to aggregate ideas and strategies for introducing a Mathematics concept in a classroom at all levels. I think right start would definitely help in making lesson easy to understand as well as interesting.

Michael Friedberg commented on Danny Clarke's group Teaching developmental math
"To my impression and concern - the student must climb up the ladder of independence. If the teacher makes by himself all the investigation work and presents to pupil only a final technological process - that is the assembly - line school. Sometimes…"

Michael Friedberg replied to Colin McAllister's discussion Straight Edge and Compass Construction For Developmental Math in the group Teaching developmental math
"Dear Colin! I`m fully agree with a final construction. When I solved this problem for myself - I had to conduct the study of investigation and revealed, what will be the ratios of consequent section of the diagonal - they were 1 : 1 : (V2 - 1). The…"

Michael Friedberg commented on Danny Clarke's group Teaching developmental math

Michael Friedberg commented on Danny Clarke's group Teaching developmental math
"One can get an impression that there is nothing to discuss - everything looks successful and friendly to students. Are there any undecided problems?"

Welcome to Mathematics 24x7. The purpose of this network is to just talk about all possibilities in Mathematics .There are people who love this subject and at the same time there are ones who are struggling for it.
Let us join our hands and look for all possibilities to make it interesting for everybody.

Keep Sharing.
