This End of Unit Assessment is used in conjunction with the Illustrative Mathematics Curriculum and the Unit 1 End of Unit Assessment Rubric. It breaks down identifying the Essential Standard associated. This assessment should be utilized with the uploaded rubric to track progress towards proficiency on each of the grade level standards.

This Check Your Readiness Assessment is used in conjunction with the Illustrative Mathematics Curriculum. It breaks down identifying the Essential Standard associated. This assessment should be utilized with the uploaded rubric to determine levels of prerequisite skills when beginning a new unit and allow for placement of interventions.

This Check Your Readiness Rubric is used in conjunction with the Illustrative Mathematics Curriculum. It breaks down each question by identifying the Essential Standard associated and then defining what an Advanced, Proficient, Basic or Below Basic student response would entail. This rubric can then be utilized to determine levels of prerequisite skills when beginning a new unit and allow for placement of interventions.

This End of Unit Assessment is used in conjunction with the Illustrative Mathematics Curriculum and the Unit 3 End of Unit Assessment Rubric. It breaks down identifying the Essential Standard associated. This assessment should be utilized with the uploaded rubric to track progress towards proficiency on each of the grade level standards.

This is a Professional Development Resource to support the implementation of a high-quality math resource (Math Expressions, 2018), and provide professional learning around the Geometry progressions.  This professional learning is appropriate for all levels of math educators but focuses on math education for grades 5-8.  It provides educators an opportunity to develop a deeper understanding and make connections to their own grade level Geometry standards.

This task shows how to inscribe a circle in a triangle using angle bisectors. A companion task, ``Inscribing a circle in a triangle II'' stresses the auxiliary remarkable fact that comes out of this task, namely that the three angle bisectors of triangle ABC all meet in the point O.

This task is primarily for instructive purposes but can be used for assessment as well. Parts (a) and (b) are good applications of geometric constructions using a compass and could be used for assessment purposes but the process is a bit long since there are six triangles which need to be constructed.

This task provides an opportunity for students to apply triangle congruence theorems in an explicit, interesting context.

This problem introduces the circumcenter of a triangle and shows how it can be used to inscribe the triangle in a circle. It also shows that there cannot be more than one circumcenter.

This task focuses on a remarkable fact which comes out of the construction of the inscribed circle in a triangle: the angle bisectors of the three angles of triangle ABC all meet in a point.

This lesson unit is intended to help teachers assess how well students are able to use geometric properties to solve problems. In particular, it will help you identify and help students who have difficulty: decomposing complex shapes into simpler ones in order to solve a problem; bringing together several geometric concepts to solve a problem; and finding the relationship between radii of inscribed and circumscribed circles of right triangles.

The applets in this Interactive Geometry Dictionary (IGD) will allow students an opportunity to explore finding the area of some common shapes. The applets demonstrate how to find the area of a triangle using the area of a parallelogram, which in turn can be found using the area of a rectangle. This tool also supports the lesson "What's My Area" cataloged separately.

In this lesson students are introduced to various types of symmetry. After exploring the symmetries that exist with letters of the alphabet, they make inversions of their own name. Suggestions for implementation and support materials are provided.

This Java interactive tool can be used to create dynamic drawings on an isometric dot grid, and to explore volume, surface area, and congruence concepts. Users can draw figures using edges, faces, or cubes and can shift, rotate, color, decompose, and view figures in 2‑D or 3‑D with this applet. Instructions on using and exploring with the tool are included on the page. A related multi-lesson unit from Illuminations for middle school students is linked to the side.

This task is closely related to very important material about similarity and ratios in geometry.

This google slide show is for use with kindergarten students as a routine to build number sense and use of geometric vocabulary. Geometric images are used to use as a springboard for discussion. How many? How did you see it? How many sides? How many faces? What shapes did you see?
