The following video addresses these student expectations for Kindergarten math.

(3) Number and operations. The student applies mathematical process standards to develop an understanding of addition and subtraction situations in order to solve problems. The student is expected to:

(A) model the action of joining to represent addition and the action of separating to represent subtraction; 

(B) solve word problems using objects and drawings to find sums up to 10 and differences within 10; and

(C) explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences.

The video also addresses the following Texas Essential Knowledge and Skills for grade 1.

(3) Number and operations. The student applies mathematical process standards to develop and use strategies for whole number addition and subtraction computations in order to solve problems. The student is expected to:

(D) The student is expected to apply basic fact strategies to add and subtract within 20, including making 10 and decomposing a number leading to a 10;

(E) The student is expected to explain strategies used to solve addition and subtraction problems up to 20 using spoken words, objects, pictorial models; and number sentences;

and

(5) Algebraic reasoning. The student applies mathematical process standards to identify and apply number patterns within properties of numbers and operations in order to describe relationships. The student is expected to:

(D) represent word problems involving addition and subtraction of whole numbers up to 20 using concrete and pictorial models and number sentences
