Composing and Decomposing Numbers to 10 Assessment
Digital Tool/Resource:
Exit Slip for Composing and Decomposing Numbers to 10
Web Address – URL:
Overview:

In this activity, students will be assessed on decomposing a given number less than 10 into at least two pairs of smaller numbers and record their solutions using a number bond and number sentence.

This activity was created as a result of the ALEX Resource Development Summit.
  Associated Standards and Objectives  
Content Standard(s):
Mathematics
MA2019 (2019)
Grade: K
10. Decompose numbers less than or equal to 10 into pairs of smaller numbers in more than one way, by using concrete objects or drawings, and record each decomposition by a drawing or equation.

Example: 5 = 2 + 3 and 5 = 4 + 1
Unpacked Content
Evidence Of Student Attainment:
Students:
  • Use objects or drawings to decompose the given number into at least two pairs of smaller numbers.
  • Record their solutions using pictures or equations.
Teacher Vocabulary:
  • Decompose
  • Equation
Knowledge:
Students know:
  • "equal to" and the concept of equality meaning "the same as."
  • Addition is putting together numbers and subtraction is taking apart numbers.
Skills:
Students are able to:
  • Represent quantities physically, pictorially, and symbolically.
Understanding:
Students understand that:
  • quantities may be named in a variety of ways.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.K.10.1: Identify plus, minus, and equal signs.
M.K.10.2: Match numerals to objects or drawings.
M.K.10.3: Identify numerals 1 to 10.
M.K.10.4: Count 0 to 10.

Prior Knowledge Skills:
  • Notice same/different and some/all.
  • Recognize numbers from one to ten.
  • Subtract one from a set of objects (up to five objects).
  • Add one to a set of objects (up to five objects).
  • Given a group of objects (ten or less), divide the group into smaller groups in various ways.
  • Given small groups of objects, create larger groups by combining the small groups.
  • Take away objects from a large group to create two smaller groups.
  • Put together two small groups of objects to create a larger group.
  • Establish one-to-one correspondence between numbers and objects when given a picture a drawing or objects.
  • Rote count to ten.
Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.K.8 Demonstrate an understanding of addition as "putting together" or subtraction as "taking from" in everyday activities, limited to 5 objects.
Learning Objectives:

Students are able to:
- use objects or drawings to decompose the given number into at least two pairs of smaller numbers.
- record their solutions using pictures or equations. 
  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

  1. The teacher will print the exit slip for each student.

  2. Students will be given a number less than or equal to 10 to represent on the printed exit slip.

  3. Students will illustrate the given number into at least two pairs of smaller numbers on the number bond.

  4. Students will then complete the sentence frame writing the number pairs that make up the given number.
Assessment Strategies:

The exit slip will be used as the assessment.

Collect exit slips and use the following guidelines to ensure students met the learning objective.

Check that the student:

  1. was able to decompose the given number into two pairs of smaller numbers.

  2. was able to record their solutions in the sentence frame using correct numbers.
Advanced Preparation:

Make a copy of the Exit Slip for each student.
Variation Tips (optional):

Once your students have mastered representing the given quantity physically, pictorially, and symbolically, encourage them to record the equation that represents their decomposition.
Notes or Recommendations (optional):
