3D对象 - 它们在我们周围！实际上，它们围绕着我们，以至于成年人几乎没有注意到它们的存在！但这并不总是这样……在过去的某个时刻，我们的老师使用了一个3D对象单位计划来教我们这些有趣的对象是什么。现在，为学生做同样的事情是我们的工作！
比较海报上的2D形状和3D对象canhelp students learn the concepts behind 3D objects… but, we thought you might be after something a little more exciting! Our awesomely amazing resource creator, Tom, has put together a课程对齐, gamified maths unit to blow your students’ minds – and help them to remember 3D objects forever.
Shape Seekers 3D对象单位计划
这Shape Seekers单位是一组互动的，由故事驱动的课程，学生可以帮助Dede教授测试一项名为的发明“The Dimensionator”。This mysterious device, left to him by his grandmother, can turn 2D shapes into 3D objects!
访问学生的先验知识
这story, activities and questions for this unit are all contained in theShape Seekers PowerPoint。它被分解为易于导航的章节。这个PowerPoint充满了引人入胜的动画，可帮助学生可视化从2D形状到3D对象的转换过程。
本单元计划的有趣介绍要求孩子们获得形状和几何形状的先验知识。看看您的学生对2D形状的记忆，并通过有趣的视频了解他们对3D对象的先验知识。然后，将这些知识与比较活动一起脚打！哦，不要忘记那些动手的物体。毕竟，您需要将它们带进去，以便可以对机器进行校准！
Wrap up this part of the unit with some thought-provoking questions:
- Out of the 3D objects types that were brought from home, which was the most common?
- What are the main three features of a 3D object?
- 确定面部，角或边缘的数量时，您是否可以使用任何快捷方式？
学会对棱镜进行分类
Help Professor Dede to operate his machine by answering questions about how many faces, vertices and edges particular 3D objects have.
然后，介绍有史以来最有趣的动手活动！为您的学生提供画一个2D形状的小镇资源。最好的部分是,这傅n activity will be continued over the course of the unit. Each lesson presents your students with a set of clues to solve that lead to something mysterious!
有关此引人入胜的活动的更多信息，请确保阅读Holly的博客Three in One Geometry Fun (Build a Town Geometry Activity)。
低下金字塔和其他3D对象
This awesome unit presents information to students in a fun, gamified way! Reward students with additional clues each time an object is created.
从一个简单的正方形开始，了解如何将许多2D形状转换为3D对象。
然后，一旦您的学生掌握了简单的棱镜和金字塔，他们就可以转移到更独特的3D物体，例如球体，圆柱体和十二面体！
不要忘记3D对象评估！
It’s time to get hands-on with some model making! In this fun assessment, students will demonstrate their 3D model-making abilities, as well as their understanding of the features of 3D shapes.
这评估 - 3D对象概况requires a bit of forethought, so make sure you read through it and gather all the necessary construction materials for your students beforehand.
正如我们说的，this unit is perfect for differentiation呢
As the Year 2 content descriptions from the Australian Curriculum don’t reference making models, there is an easy way to differentiate this assessment piece down.
只需向学生提供3D对象图片卡Let’s Sort It! – 2D Shapes and 3D Objects Sorting Activity。这n, encourage your class to choose 3 objects and stick the pictures on the template page. To finish, they can describe the details for each object – simple!
您的学生将立即成为这个3D对象单元计划的2D形状和3D对象的硕士！
