COMPUTATION & ALGEBRAIC REASONING

  • 1.CAR.1 Add and subtract fluently within 10 with mastery by the end of first grade.
  • 1.CAR.2 Use computational fluency to add and subtract within 20 using manipulatives and/or a variety of strategies.
  • 1.CAR.3 Apply properties of operations to add and subtract within 20.
  • 1.CAR.4 Use concrete models or drawings to add within 100, including a two-digit number and a one-digit number as well as a two-digit number and a multiple of ten; relate strategy used to a written expression or equation and explain reasoning.
  • 1.CAR.5 Demonstrate the relationship between addition and subtraction by solving problems, using an inverse operation.
  • 1.CAR.6 Solve real-world problems involving addition and subtraction within 20. Problem types include: adding to, taking from, putting together, taking apart, and comparing with unknowns present throughout the addition and subtraction problem.
  • 1.CAR.7 Solve real-world problems involving addition of three whole numbers whose sum is less than or equal to 20.
  • 1.CAR.8 Apply understanding of the equal sign to determine if equations involving addition and subtraction are true or false.
  • 1.CAR.9 Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.

DATA ANALYSIS

  • 1.DA.1 Organize, represent, and interpret data with up to three categories (e.g., tally tables, picture graphs, bar graphs).
  • 1.DA.2 Ask and answer questions about the total number represented such as how many in each category and how many more or less in one category compared to another.

GEOMETRY & MEASUREMENT

  • 1.GM.1 Understand the difference between defining attributes (e.g., triangles are closed and three-sided shapes) and non-defining attributes (e.g., color, orientation, overall size), using that understanding to build and draw shapes that exhibit defining attributes.
  • 1.GM.2 Create a composite shape using two-dimensional or three-dimensional shapes. Two-dimensional include: rectangle, square, trapezoid, triangle, hexagon, half circle, and quarter circle. Three-dimensional include: cube, rectangular prism, cone, and cylinder
  • 1.GM.3 Express the length of an object as a whole number of units by laying multiple copies of a shorter object end-to-end, understanding that the length of one object is equal to the number of same-size units that span the object with no gaps or overlaps.
  • 1.GM.4 Order three objects by their length, indirectly comparing the lengths of two objects by using a third object.
  • 1.GM.5 Tell and write time to the nearest hour and half hour using analog clocks; understand how to read hours and minutes using digital clocks.
  • 1.GM.6 Identify coins by name and value, including penny, nickel, dime, and quarter.
  • 1.GM.7 Count collections of like coins including pennies, nickels, and dimes to determine their total value up to 100 cents.

NUMBER & PLACE VALUE

  • 1.NPV.1 Count forward and back within 120 by ones and tens from any given whole number.
  • 1.NPV.2 Skip count forward by multiples of fives within 120.
  • 1.NPV.3 Explain the place value of ones and tens in two-digit numbers, using concrete models, diagrams, numbers, or words.
  • 1.NPV.4 Read, write, and represent whole numbers up to 120, using concrete models or drawings, word form, base ten numerals, and expanded form.
  • 1.NPV.5 Use concrete models or drawings to subtract multiples of 10 from multiples of 10 (within the range of 10-90), relate the strategy to a written expression or equation, and explain the reasoning used to solve.
  • 1.NPV.6 Use mental strategies to find 10 more or 10 less than a given two-digit number.
  • 1.NPV.7 Compare two two-digit numbers using symbols (<, =, >) based on the value of tens and ones in the given numbers.
  • 1.NPV.8 Partition circles and rectangles into two and four equal shares, describing the shares using the words halves, fourths, and quarters; understand that decomposing into more equal pieces creates smaller pieces.
