Timeline: 10 days
Unit 4 Title: 3D Shapes
This unit will give the opportunity for students to learn about 3-dimensional shapes in their everyday lives. They will have the opportunity to give specific names to the various 3D shapes. In addition to learning about the 3-dimensional shapes they will also be able to build the shapes and compare them to two-dimensional shapes.
At the end of this unit, all students must be able to recognize 3D shapes in their environment. They also must be able to name each of the 3-Dimensional shapes they are introduced to throughout the unit. Finally, they must be able to explain the difference between 3D and 2D shapes.
PA.CCSS.Math.Content.CC.2.3.K.A.1 Identify and describe two- and three- dimensional shapes. (K.G.1, K.G.2, K.G.3)
PA.CCSS.Math.Content.CC.2.3.K.A.2 Analyze, compare, create, and compose two- and three-dimensional shapes. (K.G.5)
Mathematical Practice Standards:
#1 Make sense of problems and persevere in solving them.
proficient students start by explaining to themselves the meaning of a
problem and looking for entry points to its solution. They analyze
givens, constraints, relationships, and goals. They make conjectures
about the form and meaning of the solution and plan a solution pathway
rather than simply jumping into a solution attempt. Proficient students
check their answers to problems using a different method. They
continually ask themselves, “Does this make sense?” They can understand
the approaches of others to solving complex problems and identify
correspondences between different approaches.
#4 Model with mathematics.
proficient students can apply the mathematics they know to solve
problems arising in everyday life, society, and the workplace. In early
grades, this might be as simple as writing an addition equation to
describe a situation.
#5 Use appropriate tools strategically.
tools might include pencil and paper, concrete models, a ruler,a
protractor, a calculator, a spreadsheet, a computer algebra system, a
statistical package, or dynamic geometry software. Proficient students
are sufficiently familiar with tools appropriate for their grade or
course to make sound decisions about when each of these tools might be
helpful, recognizing both the insight to be gained and their
limitations. Mathematically proficient students at various grade levels
are able to identify relevant external mathematical resources, such as
digital content located on a website, and use them to pose or solve
problems. They are able to use technological tools to explore and deepen
their understanding of concepts.
#6 Attend to precision.
proficient students try to communicate precisely to others. They try to
use clear definitions in discussion with others and in their own
reasoning. They state the meaning of the symbols they choose, including
using the equal sign consistently and appropriately. They are careful
about specifying units of measure, and labeling axes to clarify the
correspondence with quantities in a problem. They calculate
accurately and efficiently, express numerical answers with a degree of
precision appropriate for the problem context. In the elementary grades,
students give carefully formulated explanations to each other. By the
time they reach high school they have learned to examine claims and make
explicit use of definitions.
Concepts - Students will know:
- How to find 3D shapes
- How to name 3D shapes

- Name each 3D shape
- Give examples of attributes for 2D and 3D shapes
- Kindergarten Checklist Components
Elements of Instruction:
Students describe their physical world using geometric ideas (e.g., shape, orientation, spatial relations) and vocabulary. They identify, name, and describe basic two-dimensional shapes, such as squares, triangles, circles, rectangles, and hexagons, presented in a variety of ways (e.g., with different sizes and orientations), as well as three-dimensional shapes such as cubes, cones, cylinders, and spheres. They use basic shapes and spatial reasoning to model objects in their environment and to construct more complex shapes.
