Texas Essential Knowledge and Skills (TEKS)
TX.111.2. Kindergarten, Adopted 2012
K.2. Number and operations. The student applies mathematical process standards to understand how to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system. The student is expected to:
K.2 (A) Count forward and backward to at least 20 with and without objects.
K.2 (B) Read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures.
K.2 (C) 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.2 (H) Use comparative language to describe two numbers up to 20 presented as written numerals.
K.2 (I) Compose and decompose numbers up to 10 with objects and pictures.
K.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:
K.3 (A) Model the action of joining to represent addition and the action of separating to represent subtraction.
K.3 (B) Solve word problems using objects and drawings to find sums up to 10 and differences within 10.
K.3 (C) Explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences.
K.4. Number and operations. The student applies mathematical process standards to identify coins in order to recognize the need for monetary transactions. The student is expected to identify U.S. coins by name, including pennies, nickels, dimes, and quarters.
K.5. Algebraic reasoning. The student applies mathematical process standards to identify the pattern in the number word list. The student is expected to recite numbers up to at least 100 by ones and tens beginning with any given number.
K.6. Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:
K.6 (A) Identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles.
K.6 (D) Identify attributes of two-dimensional shapes using informal and formal geometric language interchangeably.
K.6 (E) Classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size.
