Math: Number Concepts to 20

• K.2B read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures
  • K.2A count forward and backward to at least 20 with and without objects
  • K.2C count a set of objects up to at least 20 and demonstrate that the last number said tells the number of objects in the set regardless of their arrangement or order
  • K.2F generate a number that is one more than or one less than another number up to at least 20
  • RRISD K.2A Use language, including before and after, forward and backward, and left and right, to describe relative position in a sequence of events or objects

Comparing Quantities

• K.2H use comparative language to describe two numbers up to 20 presented as written numerals
  • K.2D recognize instantly the quantity of a small group of objects [up to 10] in organized and random arrangements
  • K.2E generate a set using concrete and pictorial models that represents a number that is more than, less than, and equal to a given number up to 20
  • K.2G compare sets of objects up to at least 20 in each set using comparative language

• K.2I compose and decompose numbers up to 10 with objects and pictures

Counting Patterns

• K.5 The student is expected to recite numbers up to at least 100 [80 in this unit] by ones and tens beginning with any given number

Counting Collections (Suggested: 5 days, using both numeracy and spiral review time)

• K.5 The student is expected to recite numbers up to at least 100 [80 in this unit] by ones and tens beginning with any given number [beginning with 1 in this unit]

Sorting and Displaying Data (Suggested: 8 days)

• K.8B use data to create real-object and picture graphs
  • K.8A collect, sort, and organize data into two or three categories
• K.8C draw conclusions from real-object and picture graphs

Sorting and Classifying 3-D Figures (Suggested: 6 days)

• K.6E classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size
• K.6B identify three-dimensional solids, including cylinders, cones, spheres, and cubes, in the real world
• K.6C  identify two-dimensional components of three-dimensional objects

Sorting and Classifying 2-D Figures (Suggested: 6 days)

• K.6E classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size
  • K.6A identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles
  • K.6D identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably
  • K.6F create two-dimensional shapes using a variety of materials and drawings
