3.8 Geometry - two-and three dimensional figures

3.8 The student uses formal geometric vocabulary. The student is expected to identify, classify, and describe two-and three dimensional geometric figures by their attributes.  The student compares two-dimensional figures, three-dimensional figures, or both by their attributes using formal geometry vocabulary.

2.7 The student uses attributes to identify two-dimensional geometric figures. The student compares and contrasts two and three-dimensional geometric figures, or both. 2.7A describe attributes (the number of vertices, faces, edges, sides) of two-and three-dimensional geometric figures, such as circles, polygons, spheres, cones, cylinders, prisms, and pyramids, etc. 2.7B use attributes to describe how two dimensional or three dimensional goemetric figures are alike or different	3.8 The student uses formal geometric vocabulary. The student is expected to identify, classify, and describe two-and three dimensional geometric figures by their attributes.  The student compares two-dimensional figures, three-dimensional figures, or both by their attributes using formal geometry vocabulary.	4.8 The student identifies and describes attributes of geometric figures using formal geometric language 4.8A identify and describe right, acute, and obtuse angles 4.8B identify and describe parallel and intersecting (including perpendicular) lines using concrete objects and pictorial models 4.8C use essential attributes to define two-and-three dimensional geometric figures.

Activities: 

• use Venn diagrams or thinking maps to compare and contrast 2-and 3- dimensional shapes
• create an organized chart to record the attributes of 2-and- dimensional shapes
• Find pictures or real life objects to represent various 2-and 3- dimensional shapes
• examples and non-examples using geoboards
• united streaming
• Make a poster of the attributes of 2 and 3 dimensional shapes
• Sorting mats to sort 2 and 3 dimensional shapes by attribute
• magazine or internet scavenger hunt for 2 and 3 dimensional shapes
• share drive--songs from Ron Brown about quadrilaterals
• students and teacher brings real-life objects and use sticky dots and electrical tape to label the edges and vertices
• students create a "geo-pet" or "geo-structure" from real-life objects

Anchor Activities:

• Kamico matching game--students match the description of a geometric figure with the concrete model of the figure
• Students sort 3D figures by attributes.  Some students sorted by number of vertices, others sorted by number of edges, and others sorted by the shape of the face.

•  Using the computer, students find 3-D figures on the internet, label, and write attributes about the figure.
