Сценарий урока алгебры в 9 классе "Перестановки и их применение в решении комбинаторных задач"

Цели урока:

1.Формирование у обучающихся представлений о способах и методах математического описания реальных процессов и явлений.

2.Содействовать развитию вычислительной культуры школьников.

3.Способствовать овладению школьниками навыками математического моделирования.

Формируемые компетенции:

  • способность строить и преобразовывать математические модели жизненных (бытовых) процессов;
  • способность анализировать   совокупности однородных объектов;
  • способность к построению логических умозаключений.

Уровень сложности:

средний; для общеобразовательных классов

Условия применения:

  • наличие у обучающихся опыта изучения элементов комбинаторики в 5-8 классах;
  • использование учебника алгебры авторов Макарычева Ю.Н. и др.;
  • достаточный уровень мотивации обучающихся к изучению математики .

Возможные риски:

  • несформированность навыков аналитического мышления у обучающихся;
  • непонимание обучающимися математики как науке о методах познания окружающего мира, что может проявиться в «развлекательном» восприятии комбинаторных задач;
  • данный раздел («Комбинаторика») в школьной математике   введен недавно, у многих учителей нет должного опыта его преподавания, методы изучения нового материала могут быть исполнены не полностью, фрагментарно.

Тип урока:

урок изучения и закрепления нового материала.

I don't know if it's just me or if everybody else encountering
issues with your blog. It appears as if some of the text on your
posts are running off the screen. Can someone else please
provide feedback and let me know if this is happening to them
as well? This could be a issue with my web browser because
I've had this happen before. Appreciate it

You actually make it seem so easy with your presentation but I find this topic
to be actually something that I think I would never understand.

It seems too complicated and extremely broad for me. I am looking forward for your next post, I'll try to
get the hang of it!

let me tell you, you've hit the nail on the head. The issue is an issue that too few men and women are speaking intelligently about.

I am very happy that I found this during my search for something regarding this.

I think everything said was very logical. However, think
on this, what if you added a little information? I mean, I don't wish
to tell you how to run your website, but what if
you added a post title that makes people want more?

I mean Сценарий урока алгебры в 9 классе "Перестановки и их применение в решении комбинаторных задач" is kinda boring.
You could peek at Yahoo's front page and see how they create post headlines to get people interested.
You might add a video or a picture or two to grab readers excited about everything've got to say.
Just my opinion, it might bring your posts a
little bit more interesting.
