您三年级学习的5件令人难以置信的知识

Insecond grade，学生开始对乘法和划分作为概念发展理解。今年，他们正在学习如何繁殖和分裂。

三年级是越来越复杂的数学的设置，这些操作占据了中心舞台。其中一些新math将被记住（这本身可能是一种新实践）：您将收听至少12 x 12的乘法表朗诵[来源：女士家庭日报]。但是，您的三年级学生也将使用今年第一次遇到的流程进行一些严肃的数学方程式。教师通常希望他们的学生学会将双位数字乘以单位数字，并划分相同，并开始使用相关概念（例如分数和小数）。

So by the end of the year, your baby might be helping you calculate the tip. And that's just the beginning. In language, too, your child may encounter some concepts that are, for the most part, truly new.

When your child enters third grade, "writing" takes on new meaning. Last year, it was basically the process of forming letters and words and putting them together to convey an idea. This year,writing获得语法。

Your child will be introduced to the complicated world of parts-of-speech and sentence structure, which means both reading and writing will become far more technical, requiring a deeper understanding of language and its patterns and uses.

Words become "verbs," "nouns," "adjectives" and "articles." Words or groups of words can be "subjects" or "predicates." Sometimes, sentences are "transitions." Writing can be "informative" or "persuasive;" it can be composed of "paragraphs," and it often ends with a "clincher."

This will likely be your child's first experience with this type of technical grammar and language instruction. Some pick it up quickly, while others take a while to catch on. Either way, your third-grader will finish this year with a dramatically increased sense of the structures and patterns underlying the language they've been speaking for so many years.

也许更大（或至少更多动手实践），您的孩子将开始掌握他或她一直生活的世界的结构和模式...

Up to now, science class participation has mostly been listening and looking. In third grade, science gets very hands-on, and your child may discover he or she is all about experimenting.

Third graders will conduct simple experiments independently and in groups, and will participate in teacher-guided complex ones. Less hands-on but nearly as exciting, your child will be exploring in some deep space, geology, climate, life cycles of plants and animals, and other topics that can open young minds to the incredible workings of the world around them.

Space, in particular, can become quite a focus. Around this age, lots of kids decide to become宇航员当他们长大时，与空间有关的事情可能是科学项目的首选主题。您甚至可能开始听到有关太空营的消息（是的，这是一件真实的事情！），您的孩子几乎足够大了。（看太空营的运作方式了解它。）

然后是动手较少的，但是就像令人难以置信的三年级发展一样...

在学校，尤其是在早期，大多数问题都有一个正确的答案。哪个图表显示了游戏中最高的积分数？主角有吗红发还是棕色？多少卫星地球有吗？

In third grade, things get more interpretative. Your child will be encouraged to use a lot more reasoning, perspective and analysis. Inmath，您的孩子会被要求解释结果，而不仅仅是阅读它们：此图告诉您有关得分点的信息？当她摔下自行车时，您认为主角的头部如何？如果有生物生活在月球上，它们会是什么样，为什么？

当一个问题有多个正确的答案时，需要思考，这是一个巨大的三年级课：有时候，您决定它的含义，表现或需要。如果您可以备份它，那是对的！

And finally, another eye-opener that will change how your child experiences life and knowledge.

您的孩子可能已经使用某种形式的计算机已经多年了玩记忆游戏，查看图片，通常只是在技术上玩乐。在一年级和二年级时，互联网通过指导课程进入了方程式。今年，您的孩子会发现网络可以做什么。

No longer just an instrument of fun and imagery, the Internet will become a place for research -- for finding answers to any questions you have. Third graders will learnhow to efficiently use search enginesand how to determine which Web sites are credible sources of information and which aren't. They'll use online resources for research projects. Some might even learn to type.

Your third grader will experience technology as "information technology," opening up a whole new world of access to knowledge. It might make you seem a bit less all-knowing, but the ability to find answers independently is a priceless one that will affect how your child learns, works and experiences the world for the rest of his or her life.

谁知道，您的三年级生可能最终会教您一两件事，因为这些课程每天都会以作业形式回家 - 今年每晚约30分钟。因此，清理厨房桌子，请记住：帮助，不要做！
