Unit 5

Geometry: Shapes, Attributes, and Solids

 

Kindergarten

Math

Unit Length and Description:

 

This unit should last approximately 4 weeks. The content of this unit should be taught throughout the year with activities integrated into all content areas.

 

 

This unit focuses on identifying, describing and classifying two- and three-dimensional shapes. Activities also continue to reinforce counting to 100 by ones and tens.

 

Standards:

 

CCSS for Mathematical Content

Measurement and Data

K.MD.1

Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.

K.MD.2

Directly compare two objects with a measurable attribute in common, to see which object has “more of”/“less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

K.MD.3

Classify objects into given categories, count the number of objects in each category and sort the categories by count

Geometry

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 orientation 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 lengths).

K.G.5

Model shapes in the world by building shapes from components (e.g., stick and clay balls) and drawing shapes.

K.G.6

Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”

Standards for Mathematical Practice (MP)

MP.3

Construct viable arguments and critique the reasoning of others.

MP.6

Attend to precision.

MP.7

Look for and make use of structure.

Standards: Instructional Outcomes

Geometry

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.

·         I can name the position words. (above, below, beside, in front of, behind, and next to)

·         I can identify the position of objects.

 

K.G.2: Correctly name shapes regardless of their orientation or overall size.

·         I can name shapes.

 

K.G.3: Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”)

·         I can identify 2 dimensional shapes.

·         I can identify 3 dimensional shapes.

 

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 lengths).

·         I can identify the number of sides and points a shape has.

·         I can describe two and three dimensional shapes.

·         I can compare and contrast two and three dimensional shapes.

 

K.G.5: Model shapes in the world by building shapes from components (e.g., stick and clay balls) and drawing shapes.

·         I can identify shapes in the real world.

·         I can use attributes to determine shapes in the real world.

·         I can make shapes.

·         I can draw shapes.

 

K.G.6: Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”

·         I can use more than one shape to make a larger shape.

 

Measurement and Data

K.MD.1: Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.

·         I can name the position words. (above, below, beside, in front of, behind, and next to)

·         I can identify the position of objects.

 

K.MD.2: Directly compare two objects with a measurable attribute in common to see which object has “more of/less of” the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

·         I can compare two objects and describe them using their measurable attributes – length, width, height, weight.

 

K.MD.3: Classify objects into given categories, count the number of objects in each category and sort the categories by count.

  • I can recognize attributes of size, shape and color.
  • I can identify how objects are the same and different.
  • I can sort.

I can group in order by number (objects in groups are 10 or less).

Enduring Understandings:

 

·         I can describe my world by using shapes and their position.

·         I can identify two-dimensional and three-dimensional shapes based on their attributes.

·         I can sort shapes in different ways.

·         I can tell how shapes are alike and how they are different.

·         I can use small shapes to make larger shapes.

 

Essential Questions:

 

·         Why is learning about shapes important?

·         How can I sort and tell about shapes?

·         How can I use two-dimensional shapes to make new shapes?
