# Math: Building Number Concepts

### Suggested Time Frame: 29 Instructional Days

##### Focus TEKS

Counting and Representing Quantities

• K.2A count forward and backward to at least 20 with and without objects
• K.2B read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures
• 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.2D recognize instantly the quantity of a small group of objects [up to 10] in organized and random arrangements

Comparing Quantities

• 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.2F generate a number that is one more than or one less than another number up to at least 20
• K.2G compare sets of objects up to at least 20 in each set using comparative language
• K.2H use comparative language to describe two numbers up to 20 presented as written numerals
##### Numeracy TEKS

Subitizing

• K.2D recognize instantly the quantity of a small group of objects [10 or less in this unit] in organized and random arrangements

Counting Patterns

• K.5 The student is expected to recite numbers up to at least 100 by ones and tens beginning with any given number
• K.5 The student is expected to recite numbers up to at least 100 by ones and tens beginning with any given number [multiple of ten]
##### Spiral Review TEKS

Number Relationships

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

Joining and Separating Quantities

• K.3A model the action of joining to represent addition and the action of separating to represent subtraction
• K.3B solve word problems using objects and drawings to find sums up to 10 and differences within 10
• K.3C explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences

Personal Financial Literacy

• K.9 Personal financial literacy. The student applies mathematical process standards to manage one’s financial resources effectively for lifetime financial security. The student is expected to:
• K.9A identify ways to earn income
