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: Materials * A copy of Grandfather Tang's Story by Ann Tompert * One set of tangrams for each student (see note in commentary) * A set of tangrams for t...

This parent guide supports parents in helping their child at home with the 1st Grade Math content.

This resource accompanies our Rethink 1st Grade Math Geometry unit. 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 unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 1st Grade Math for Geometry.

First grade students will work in small group settings to discover how to become an architectural engineer. They will research and demonstrate their knowledge of bridge designs through STEM and drawings. Finally developing a strong infrastructure that will collaboratively fit onto a created setting. Allowing them to present a model of their findings.

This short video and interactive assessment activity is designed to teach first graders about counting rectangles, squares, and triangles in composite figures.

This challenging problem and brainteaser gives first graders an opportunity to compose and decompose squares.

In this task, students are presented shown a square with nine blocks inside. Students are asked to tell the number of squares there are in the picture.

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

This task is an interesting way to have student practice making designs with pattern blocks. Students listen to "Grandfather Tang’s Story". After the story, students select animals from the story to make with the tangrams. A worksheet is provided to show the tangram animals that students can make.

This lesson uses GoMath Chapter 12 Lesson 6 resources and incorporates supplemental digital resources to reinforce lesson objectives.

This short video and interactive assessment activity is designed to teach third graders about counting the number of basic 2d shapes in a composite figure.

In this task, students are given an opportunity to practice composing and decomposing shapes by creating their own puzzle. Students are given a square colored sheet of paper and an envelope. Students cut the square into four pieces and place the pieces in an envelope. Next, students trade puzzles and try to solve each other’s puzzles by reassembling the shapes into a square.

This instructional task gives students a hands-on experience with composing and decomposing geometric figures.

This document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. Read this document prior to teaching the cluster in order to get insight into the clustering of the standards, mathematics to be taught, and important considerations.

This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.

This challenging problem and brainteaser gives students an opportunity to compose and decompose polygons to make rectangles.

Students love to paint and draw. Using Paint Online, students can practice their shapes. Teachers can assign certain shapes and the students will create pictures with those shapes in them.

Students create two identical shapes, draw and write about the new shape they made. They add another shape to the first shape they made and draw and name the shapes. A word bank is provided to assist students with names of shapes as well as an example of how to make, draw, and write about the shapes.

After watching a video story about tangrams, students will explore making shapes with tangrams and then will write a story together that is illustrated with tangram pictures.  This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
