Hueneme Elementary School DistrictStaff Development Day #3March 10, 2014 CCSS Mathematic Unit of Study Grade 1
Unit of Study: Title and Overview Title: Addition and Subtraction within 20 Length: 40 days Overview: Key Points Students will: • develop fluency + and - • apply various strategies to solve a variety of word problems • utilize objects, pictures, diagrams, and/or equations to solve problems
Focus Standards Guaranteed: Taught and Assessed (Re-taught if necessary) • 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.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).
Supporting Standards (Taught in conjunction with the Focus Standards) 1.OA.5. Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
