Solids & Flat Shapes

How are plane and solid objects different?
How do you describe 2D shapes?
How do you describe 3D shapes?
What are shapes?
Where in the world can I find shapes?
How can I put shapes together and take them apart to form other shapes?
How can I identify and describe solid figures by describing the faces, edges, and sides?
How can I identify and describe flat shapes by describing the faces, edges, and sides?
How are plane and solid objects different?
How can I put shapes together and take them apart to form other shapes?

Students will know and understand:

Students Will:

identify square, circle, triangle, rectangle, hexagon, cube, cone, cylinder, and sphere and state if they are 2D or 3D shapes.
manipulate and join shapes to make new shapes.
identify different attributes of 2D and 3D shapes.
draw and build shapes.

Formative Test: Common

Upon completion of Unit 7:

K.CC.A.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
K.CC.B.4. Understand the relationship between numbers and quantities; connect counting to cardinality.
K.G.A.2. Correctly name shapes regardless of their orientations or overall size.
K.G.A.3. Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
K.G.B.4. Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).
K.G.B.5. Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
K.G.B.6. Compose simple shapes to form larger shapes.
MP.1. Make sense of problems and persevere in solving them.
MP.2. Reason abstractly and quantitatively.
MP.3. Construct viable arguments and critique the reasoning of others.
MP.4. Model with mathematics.
MP.5. Use appropriate tools strategically.
