# Math: The Concepts of More, Less, and the Same

### Suggested Time Frame: 25 Instructional Days

##### Focus TEKS

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 [at least 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]
• K.2G compare sets of objects up to at least 20 [10 in this unit] in each set using comparative language
• K.2H use comparative language to describe two numbers up to 20 [at least 10 in this unit] presented as written numerals
• 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 Measurable Attributes

• K.7A give an example of a measurable attribute of a given object, including length, capacity, and weight
• K.7B compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference
##### 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 [40 in this unit] 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
