Skills Covered

• 1.OA.A.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.A.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
• 1.OA.B.3 Apply properties of operations as strategies to add and subtract.
• 1.OA.B.4 Understand subtraction as an unknown-addend problem.
• 1.OA.C.5 Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
• 1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
• 1.OA.D.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.
• 1.OA.D.8 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.
