# Math: Developing a Sense of Quantities to 10

### Suggested Time Frame: 15 Instructional Days

##### Focus TEKS

Counting and Representing Quantities to 10

• K.2B read, write, and represent whole numbers from 0 to at least 20 [10 in this unit] with and without objects or pictures
• K.2A count forward and backward to at least 20 [10 in this unit] with and without objects
• K.2C count a set of objects up to at least 20 [10 in this unit] and demonstrate that the last number said tells the number of objects in the set regardless of their arrangement or order
• 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 [10 in this unit]
• K.2F generate a number that is one more than or one less than another number up to at least 20 [10 in this unit]
• 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

Composing and Decomposing within 10

• K.2I compose and decompose numbers up to 10 with objects and pictures.
• K.2D recognize instantly the quantity of a small group of objects [up to 10 in this unit] in organized and random arrangements
##### Computational Fluency TEKS

Counting Patterns

• K.5 The student is expected to recite numbers up to at least 100 [20 in this unit] by ones and tens beginning with any given number [1 in this unit]
