This resource is from Tools4NCTeachers.  In this lesson, students create polygons on geoboards and record the polygons on geodot paper.  They write riddles about the polygons and have classmates guess their shape.  Printable Geodot paper and student work pages are included within this lesson.  Remix this lesson to include related math centers and pictures of student work.

This resource is from Tools4NCTeachers. This file contains a set of 3 tasks (including scoring rubric and recording sheets).  The tasks may be used for instruction or assessment.The focus of standard G.1 is on recognizing/drawing 2D shapes and recognizing/describing 3D shapes.  Please remix this resource to help create additional tasks - especially for 3D shapes! 

This resource is from Tools4NCTeachers.  In this lesson students will sort polygons, paying attention to their attributes.  They will use geometric vocabulary and identify their sorting rules. Sorting cards, activity sheets, and sample student solutions are included within this lesson.

This is lesson one in a series of six lessons focused around developing a mathematical community at the beginning of the school year. The primary goal of this lesson is for students to begin establishing norms for math class. A secondary goal is to start exploring a non-standard problem that has more than one possible solution.

This resource is from Tools4NCTeachers.In this lesson, students are given boxes to cut apart.  As they decompose the boxes, students notice the 2-dimensional shapes used to construct their 3-dimensional boxes.  A printable student recording sheet is provided within this lesson.Remix to include pictures of student work samples. 

In this video segment from Cyberchase, Matt, Digit and Slider must create an exact copy of a large ring in order to activate a powerful force and foil Hacker. To make sure the copy they make is perfect, they have to know what the ?radius? of a circle is and figure out a way to carefully measure it. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.
