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 aspects of the task and its potential use.

This short video and interactive assessment activity is designed to give fifth graders an overview of quadrilaterals.

This activity gives students a chance to relate some common three-dimensional solids to their polygonal faces. The object is to put solids in a sequence in which adjacent solids have a polygonal face in common. Ideas for implementation, extension, hints and support are included along with printable cards of the polyhedra.

In this activity students apply their knowledge of triangle properties. It asks students to sort three types of triangles based on angle and side comparisons, while ignoring the size and orientation differences. Students can work online with an interactive Flash applet, or on a printed sheet (included). The Teachers' Notes page includes suggestions for implementation, discussion questions, and ideas for extension.

This lesson focuses on quadrilaterals and attributes in order to classify each shape (parallelogram, rhombus, square, rectangle, and trapezoid). Students will review traits, identify shared traits and names of quadrilaterals, by identifying quadrilaterals in a video story. Then they will show their understanding by creating a quadrilateral story that explains traits and shared traits/names between quadrilaterals.This lesson will take approx 2 math sessions (or approx 120 min.)Thumbnail Image Citation: Bouwhuis, Laura.

This lesson is created as a review/assessment of geometric figures for 5th grade mathematics students. Students will create a presentation with pictures to match the figures they have learned and reviewed.  

In this problem students use spatial awareness and visualization to solve problems related to reflection (bilateral) symmetry. Learners are given three shapes and must assemble as many different but symmetrical composites as possible. Ideas for implementation, extension and support are included along with printable sheets of the shapes and a poster.
