This parent guide supports parents in helping their child at home with the 3rd grade Math content.

This resource accompanies our Rethink 3rd Grade Math Course. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Draw at least two examples and two non-examples of each of the quadrilaterals defined below. Parallelogram: A quadrilateral with 2 pairs of parallel si...

This short video and interactive assessment activity is designed to teach third graders an overview of lines, curves, vertices, and sides of 2d shapes.

This document includes sample performance tasks and assessment items for Common Core State Standards Grade 3 Math provided by the Louisiana Department of Eduation. Both questions and exemplary responses are included.

This short video and interactive assessment activity is designed to give fourth graders an overview of forming figures with cutouts.

This short video and interactive assessment activity is designed to teach third graders about counting vertices and sides in various shapes.

An interactive applet and associated web page that demonstrate the properties of a cube. A 3-D cube is shown in the applet which can be interactively manipulated using the mouse. Research has shown that some younger students have difficulty visualizing the parts of a 3D object that are hidden. To help with this, the student can rotate the cube in any axis simply by dragging it with the mouse. It can also be 'exploded' - where a slider gradually separates the faces to reveal the ones behind. The cube can also be made translucent so you see through it to the other side. Applet can be enlarged to full screen size for use with a classroom projector, and printed to make handouts. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This lesson is for grades 3 on math. At Home Learning Lessons are a partnership between the North Carolina Department of Public Instruction, PBS North Carolina, and the William and Ida Friday Institute for Educational Innovation. Each lesson contains a video instructional lesson, a PDF lesson plan with a transcript, and a PDF file of extension activities.

In this lesson, students will explore angles, rays, line segments, perpendicular lines, parallel lines, and two-dimensional figures through the use of the book “Shape Up! Fun with Triangles and Other Polygons” by David A. Adler. They will also classify quadrilaterals through an interactive website.

This 3 unit of geometry lessons explores triangles and quadrilaterals through 3 hands-on activities and 4 worksheets.

This 3 unit of geometry lessons explores quadrilaterals through 5 hands-on activities and 3 worksheets.

This document is from NC2ML and state leaders. It provides an overview for teachers about the mathematics and pedagogies in Grade 3 Cluster 5. This is not remixable since it is from state leaders.

This provides examples of anchor charts that teachers could use to teach geometry content in Grade 3 Cluster 5. This is remixable.

This CFA provides examples of items that could be used to assess students in Grade 3 Cluster 5. This can be given at once, but we recommend using the individual items or pairs of items as exit tickets and shorter assessments. This is remixable if you maintain the rigor of the items.

This task provides students with the opportunity to decompose quadrilaterals into other quadrilaterals and triangles. It aligns to NC.3.G.1. This is remixable by adding student work or you could download the task and upload a similar task.

These are the family letters for Grade 3 Cluster 5. These can be remixed.

This provides content to teachers to help them better understand their geometry content in Grade 3 Cluster 5. This is remixable if you include additional resources to support meeting the range of all learners.
