Formative Instructional and Assessment Tasks

NC.1.OA.6Add It Up: Remixed to add to continuum of understanding
DomainOperations and Algebraic Thinking
ClustersAdd and subtract within 20.Analyze addition and subtraction equations within 20.
StandardsNC.1.OA.6 Add and subtract, within 20, using strategies such as:• Counting on• Making ten• Decomposing a number leading to a ten• Using the relationship between addition and subtraction• Using a number line• Creating equivalent but simpler or known sumsNC 1.OA.8 Determine the unknown whole number in an addition or subtraction equation involving three whole numbers.
MaterialsSF, cubes or counters, pencil
TaskProvide materials to the student.  Read the problem aloud:  Solve the following equation using two different strategies.  6 + 7 = ?  
Continuum of Understanding
Not Yet Proficient
  • Incorrectly solves the problem and does not have strategies that lead to a correct answer
Strategies: Provide materials to student and read problem aloud: Solve the following equation using two different strategies:  3 + 2 (may use any combination of adding to 10)		Strategies Used:
  • Trial and Error
  • Counting All
  • Counting On
  • Makes Tens
  • Basic Facts
  • Creates easier or known sums
  • Doubles
  • Doubles +/- 1, 2
  • Other:
Progressing
  • Correctly solves the equation using two different strategies, but uses counting all as a strategy
Meets Expectations
  • Correctly solves the equation using two different strategies that do not include counting all
Standards for Mathematical Practice
1.  Makes sense and perseveres in solving problems.
2.  Reasons abstractly and quantitatively.
3.  Constructs viable arguments and critiques the reasoning of others.
4.  Models with mathematics.
5.  Uses appropriate tools strategically.
6.  Attends to precision.
7.  Looks for and makes use of structure.
8.  Looks for and expresses regularity in repeated reasoning.

Solve the following equation using two different strategies.  6 + 7 =  ?
