Operations and Algebraic Thinking
Addition and Subtraction within 20
-
1.OA.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
-
1.OA.3 Apply properties of operations as strategies to add and subtract.
Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
-
1.OA.4 Understand subtraction as an unknown-addend problem.
For example, subtract 10 - 8 by finding the number that makes 10 when added to 8.
-
1.OA.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
Number and Operations in Base Ten
Read, Write, and Count to 120
-
1.NBT.1 Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
Comparing Numbers
-
1.NBT.3 Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
