Students create and analyze composite materials with the intent of using the materials to construct a structure with optimal strength and minimal density. The composite materials are made of puffed rice cereal, marshmallows and chocolate chips. Student teams vary the concentrations of the three components to create their composite materials. They determine the material density and test its compressive strength by placing weights on it and measuring how much the material compresses. Students graph stress vs. strain and determine Young's modulus to analyze the strength of their materials.

In this lesson, students develop spatial sense by composing shapes to match their teacher's representation.

Having spatial sense means having a feel for the geometric aspects in the environment and how the different shapes can be combined to form different figures. Students do not "grow" this spatial reasoning without having rich experiences that involve shapes and spatial relationships.

This resource is from Tools4NCTeachers.  This tasks may be used for instruction or assessment.  The file contains a student shape cutouts for students to compose shapes to make a new composite shape.  The new, composite shape does not need to have a given name (e.g., trapezoide or square).Remix this leson to include student work samples or extension ideas.

Students are asked to use a set of pattern blocks to compose given shapes. This task may be used for instructional or assessment purposes.

This lesson is from Tools for NC Teachers. Students explore factors, multiples, and the concepts of prime and composite. This is remixable.

This lesson is from Tools for NC Teachers. In this lesson, students create arrays using square tiles and grid paper in order to determine the factors of numbers 1-25. The lesson will introduce students to the vocabulary of factor, multiple, prime, and composite.
