Addition and Subtraction Grades K–1
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.
