Title:
Composing and Decomposing Numbers to 10
Digital Tool/Resource:
Jack Hartmann video
Web Address – URL:
Overview:

In this learning activity, the students will watch a video about the number pairs that make up the number 5. The students will sing along with the video and perform the hand movements making number pairs for the number 5.

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:
Before/Engage
Activity:

  1. Play the video the first time just for the students to watch.

  2. Play the video the second time and ask the students to stand and sing along with the video while performing the hand movements as Jack Hartmann does in the video.

  3. The teacher will walk around the room observing the students for correct hand movements.
Assessment Strategies:

The teacher will walk around the classroom the second time the video is played to observe the students using hand movements while making the number pairs for 5.
Advanced Preparation:

The teacher will need an internet-connected device to play the video.

Prepare the students to watch a video and perform hand movements.
Variation Tips (optional):

Once your students have mastered number pairs to 5, you may show the Jack Hartmann video on number pairs to make 6.

Struggling students can be partnered with another student.
