Texas Essential Knowledge and Skills (TEKS)
TX.111.3. Grade 1, Adopted 2012
1.2. Number and operations. The student applies mathematical process standards to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to:
1.2 (E) Use place value to compare whole numbers up to 120 using comparative language.
1.2 (F) Order whole numbers up to 120 using place value and open number lines.
1.2 (G) Represent the comparison of two numbers to 100 using the symbols >, <, or =.
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:
1.3 (D) Apply basic fact strategies to add and subtract within 20, including making 10 and decomposing a number leading to a 10.
1.3 (E) Explain strategies used to solve addition and subtraction problems up to 20 using spoken words, objects, pictorial models, and number sentences.
1.5. 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:
1.5(A) Recite numbers forward and backward from any given number between 1 and 120.
1.5 (G) Apply properties of operations to add and subtract two or three numbers.
