191 Составьте синквейн к слову подарок​
nordsb [41]

"синквейн". Считается, что это стимулирует умственную деятельность учащихся, способствует развитию творческого мышления, навыков письма и чтения, умения анализировать и делать выводы, формулируя их кратко. Кроме того, очень интересно составлять синквейны, и дети с удовольствием этим занимаются.

Что такое Синквин?

Эта форма стихосложения возникла по предложению американской Аделаиды Крапси в начале прошлого века, благодаря восточным принципам поэзии - хайку и танка. В результате получился синквейн - лаконичная пятистрочная поэтическая форма, несущая синтезированную информацию. Синквейн делится на несколько разновидностей, каждая из которых имеет определенные правила составления.
