Teacher: Patricia Arredondo Subject: 2nd Grade Math Unit of Instruction: Geometry and spatial reasoning Implementation Dates: August 13-17,2012 Objective 1: 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. Objective 2: use attributes to describe how 2 two-dimensional figures or 2 three-dimensional geometric figures are alike or different. Objective 3: cut two-dimensional geometric figures apart and identify the new geometric figures formed. Curriculum Layers Student Unit Learning Activities Point Value C Layer: Basic knowledge, understanding. The student builds on his/her current level of core information. To earn a grade of “C”- 71-79 points. When you have earned 75 points you may begin working in the “B”  layer.     Geometry and spatial reasoning 1. Define the following two- and three-dimensional geometric figures such as circles, polygons, spheres, cones, cylinders, prisms, and pyramids. *2. Identify the number of vertices, faces, edges, sides on the math worksheet. 3. Complete problems 1-10 on pages 34-35 on workbook. 4. Sort geometric shapes according to its attributes 5. Listen to lesson on geometric shapes 6. Practice problems in the math page at computer station *7. Bring in 4 things from home with a different geometric shape  *8. Make a pattern quilt out of construction paper shapes 9. Color the shapes worksheets 10. Label the number of vertices, faces, edges, sides 11. Using magnetic shapes complete shape patterns 12. Sort the two dimensional shapes from the three-dimensional shapes /5     /10   /10 /10 /5 /15   /15   /15 /5 /10 /5 /5     Total____ B Layer: Application or manipulation of the information learned in the C layer. Problem solving or other higher level thinking tasks can be placed here. To earn a grade of “B” you must earn 80-89 points.   Geometry and spatial reasoning *1.
