Polygon Classification
Polly want a polygon? Young mathematicians sort shapes using an interactive. They classify the shapes as convex polygons, concave polygons, or not polygons.

Plankton
Dive into the world of plankton. The 17th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces different types of plankton. Young scientists then use what they have learned to classify...

Solid State
Crystal comes from a Greek word meaning ice. Activity eight in a series of 36 has class members analyzing amorphous and crystalline solids and further classifying them based on their forces. They then explore solids, learning about unit...

Our Geometic World
Students walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

Figure It Out - Polygons
Sixth graders explore different polygons. In this polygon lesson, 6th graders examine a rhombus, quadrilateral, parallelogram, and rectangles. Students compare and contrast polygons and research shapes on the Internet.
Curated OER
Circles, Rectangles, Squares, Triangles
Students identify, compare and classify the various shapes. In this shapes lesson, students listen to descriptions of shapes with words such as sides, angles, congruent, and parallel. Students then give the teacher examples of shapes...

A Planet Full of Animals
Pupils explore a variety of animals that live on our planet. The shapes, sizes, colors, movements, and coverings of the animals are observed. The similarities and differences in the animals are grouped according to common traits.
Curated OER
Rock Cycle SIOP Unit
Pupils collect rocks, identify them, classify them, investigate their properties, and more. In this rocks lesson plan, students also experiment with soil and erosion and weather.
Curated OER
Draw It!
Pupils follow directions to make two- and three-dimensional shapes. Focusing on polygons, they use the shapes to solve real-world problems and review with the class. They read two of Shel Silverstein's poems and discuss the arrangements...

2-D polygons
A hands-on activity uses the Zome modeling system, and helps young geometers either learn or review their knowledge of polygons. Pupils build as many different 2-dimensional polygons as possible: triangle, square, rectangle, pentagon,...
Curated OER
More Prisms/Nets
Young scholars calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.

Classifying Galaxies
Students classify galaxies by their shape using the Hubble Tuning Fork Diagram.
Curated OER
Identify, Sort, Classify
Students identify, sort, and classify. For this kindergarten math lesson, students explore visual examples of sorting with 1 or more attributes. Students also practice solving problems that their instructors model.
Curated OER
What Is in a Rock?
Students identify, sort, and classify mineral samples that make up a common rock.
Curated OER
How many edges do I need to cut in order to open a cube?
Students problem solve to open a cube to create different shapes. In this problem solving lesson plan, students are given a cube and the shapes to open it up to, and they have to cut the cube open to make certain shapes. This gives them...

Math: Shapes and More Shapes
Students locate lines of symmetry in regular polygons and predict the number of lines of symmetry in an octagon. In three different polygons, they construct all lines of symmetry and after making their prediction about the octagon,...
Curated OER
Polygon People
Students identify polygons. For this polygon people lesson, students draw required shapes and construct a polygon person. They identify each shape and its characteristics. The lesson may be extended by allowing students...

Plant Features
Pine needles are actually modified leaves. In the 16th installment of 20, young scientists explore plants. Through an analysis of leaves — shape, veins, and edges — pupils see how to classify plants based on structural features.

It Counts
Young scholars classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a...
Biology Junction
Protists and Fungi
It's alive, but what is it? Protists share similarities with plants, animals, and fungi without being classified as any of those three. Learn more about protists and the kingdom fungi with a short presentation. It describes the parts of...

Structure and Function of the Cell/Introduction to the Cell
So, this is not technically a worksheet, but rather a chapter of reading material, pictures, and diagrams introducing young biologists to the cell. Cell theory, diversity, size, and shape are described. The internal organization and...
