1.MD.4:
Measurement And Data
Represent And Interpret Data.
Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
1.MD.3:
Measurement And Data
Tell And Write Time.
Tell and write time in hours and half-hours using analog and digital clocks.
1.NBT.1:
Number And Operations In Base Ten
Extend The Counting Sequence.
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.
1.OA.5:
Operations And Algebraic Thinking
Add And Subtract Within 20.
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
1.OA.6:
Operations And Algebraic Thinking
Add And Subtract Within 20.
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.1:
Operations And Algebraic Thinking
Represent And Solve Problems Involving Addition And Subtraction.
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.2
1.OA.2:
Operations And Algebraic Thinking
Represent And Solve Problems Involving Addition And Subtraction.
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.
