Topic Twelve: Identify and Describe Shapes

Desired Results

Transfer:
1. Makes sense of problems and persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments and critique the reasoning of others.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
Established Goals:
  • K.G.1: Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
  • K.G.2: Correctly name shapes regardless of their orientations or overall size
  • K.G.3: Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
  • K.G.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).

Student I Can Statements:
  • I can name and tell about shapes I see around me.
  • I can tell where I see shapes by using words like above, below, beside, in front of, behind and next to.
  • I can name shapes no matter how big they are or which way they are turned.
  • I can tell if a shape is two-dimensional (flat) or three-dimensional (solid).
  • I can think about and compare two-dimensional and three-dimensional shapes.
Big Ideas:
Geometric Figures
Two- and three-dimensional objects with or without curved surfaces can be described, classified, and analyzed by their attributes. An object's location in space can be described quantitatively.

Practices, Processes, and Proficiencies
Mathematics content and practices can be applied to solve problems.
Essential Questions:

  • How can two and three-dimensional shapes be identified and described?
Students will know...
  • Objects have shape. Some objects, such as a sheet of paper or a photograph are two-dimensional, or flat, shapes. Some objects such as a ball, can, box, or jar are three-dimensional or solid shapes.
  • A circle is round and does not have any corners (vertices). A triangle has 3 sides and 3 corners (vertices).
  • Flat shapes called rectangles have 4 sides have 4 vertices that look the same. A rectangle looks like a door. Squares are special rectangles because their sides are all the same length.
  • Six-sided flat shapes are called hexagons. These shapes can be found in objects in objects made by people and in nature.
  • Spheres, cylinders, cones, and cubes are solid figures. Many everyday objects closely approximate these figures.
  • Objects have shape. Some objects look like flat shapes or solid shapes, including squares, rectangles, triangles, circles, hexagons, spheres, cubes, cylinders, and cones.
  • The positions of objects in relation to surrounding objects can be described using words such as above, below, beside, in front of, behind, and next to.
  • Mathematicians are careful about what they write and so, so their ideas about math are clear.

Vocabulary:
sort, two-dimensional shape (flat), three-dimensional shape (solid), circle, side, triangle, vertex/vertices (corner), rectangle, square, hexagon, cone, cube, cylinder, sphere, above, behind, below, beside, in front of, next to
