Unpacked Content
Evidence Of Student Attainment:
Students:
  • solve a variety of addition and subtraction problems, using concrete and pictorial representations.
  • explain and justify solutions using connections among a variety of representations (e.g., manipulatives, drawings, and equations with a symbol for the unknown number).
  • write equations that represent the work they have shown.
Teacher Vocabulary:
  • One-step word problems
  • Two-step word problems
Knowledge:
Students know:
  • addition and subtraction strategies to solve one- and two-step word problems within a 100.
Skills:
Students are able to:
  • represent quantities and operations (addition & subtraction) physically, pictorially, or symbolically.
  • strategically use a variety of representations to solve addition and subtraction word problem.
  • use informal and mathematical language to communicate the connections among addition and subtraction.
  • accurately compute sums and differences.
  • use symbols to represent unknown quantities in equations.
Understanding:
Students understand that:
  • addition is both putting together and adding to.
  • subtraction is taking apart, taking from, and comparisons.
  • mathematical problems can be solved using a variety of strategies, models, representations.
  • variables represent unknown quantities when representing mathematical situations algebraically.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.2.1.1: Solve one-step addition and subtraction word problems with an unknown by using drawings and equations with a symbol for the unknown number to represent the problem.
M.2.1.2: Understand key words in addition and subtraction word problems.
Examples: adding to, taking from, putting together, taking apart, sum, difference, all together, how many more, how many are left, in all.
M.2.1.3: Locate the unknown regardless of position.
Examples: start unknown, change unknown, and result unknown.
M.2.1.4: Apply signs +, -, = to actions of joining and separating sets.
M.2.1.5: Add and subtract within 50, e.g., by using objects or drawings to represent the problem.
M.2.1.6: Solve 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 or drawings to represent the problem.
M.2.1.7: Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
M.2.1.8: Represent numbers with objects or drawings.

Prior Knowledge Skills:
  • Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
  • Understand key words in addition and subtraction word problems.
    Examples: sum, difference, all together, how many more, how many are left, in all.
  • Define subtraction as separating groups of objects, taking from, or taking apart.
  • Define addition as combining groups of objects, adding to, or putting together.
  • Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
  • Represent numbers with objects or drawings.
  • Use objects to combine and separate groups.
  • Define how many, all together, and in all.
  • Count to 20 by ones.
  • Demonstrate 1:1 correspondence.
  • Mimic counting objects in sequential order arranged in a line, circle, or array.

  • Count to 10 by ones.
  • Count in sequential order.
  • Mimic counting in sequential order.
  • Demonstrate one to one correspondence.
  • Make purposeful marks such as lines and circles.
