Overview:

This learning activity should be used at the end of a lesson on recognizing angle measure as additive. The students will find missing angle measurements using a real-world problem. This learning activity can be used as an assessment.

This activity results from the ALEX Resource Gap Project.

a. Solve addition and subtraction problems on a diagram to find unknown angles in real-world or mathematical problems.
Unpacked Content
Evidence Of Student Attainment:
Students:
  • When given the measures of two adjacent angles, find the measure of the larger angle formed.
  • Given one angle measure, composed of two smaller angles and given the measure of one of the smaller angles, find the second unknown angle measure.
  • Decompose the angle as the sum of two angle parts.
  • Use addition and subtraction equations to represent and solve problems involving angle measurements.
Teacher Vocabulary:
  • Decompose
  • Angle
  • Non-overlapping
  • Angle measure
  • Sum
  • Diagram
  • Adjacent
  • Compose
  • Degrees
Knowledge:
Students know:
  • Angles are measured in degrees from 0 to 360.
  • Protractor orientation does not affect an angle measurement.
Skills:
Students are able to:
  • Decompose an angle into non-overlapping parts and demonstrate that the sum of the angle measure parts is the same as the measure of the whole angle.
  • Use addition and subtraction to find unknown angles on a diagram in real-world or mathematical problems.
Understanding:
Students understand that:
  • The rotation of an angle is measured by the number of one-degree angles that exactly cover the rotation of the angle.
  • Angle measurement is additive of the non-overlapping parts of a decomposed angle.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.4.26.1: Identify straight angles.
M.4.26.2: Recognize angle measures such as 45o, 90o, 180o, 270o, 300o.
M.4.26.3: Recall basic addition and subtraction facts.
M.4.26.4: Skip count by fives and tens.

Prior Knowledge Skills:
  • Build and draw shapes to possess defining attributes.
  • Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
  • Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles).
  • Identify a rectangle.
  • Express the length of an object as a whole number of length units by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
  • Define halves, thirds, fourths, quarters, whole, parts (shares) and equal.
  • Distinguish between equal and non-qual parts.
  • Model partitioning circles and rectangles.
  • Decompose pictures made of simple shapes.
  • Identify squares, circles, triangles and rectangles.
  • Explore shapes or figures that can be decomposed into smaller equal parts.
Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.4.24 Recognize and Identify angles in geometric shapes as larger or smaller.
Learning Objectives:

I can recognize angle measure as additive.

I can solve addition and subtraction problems to find unknown angles on a diagram in real-world problems. 
  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

This learning activity should be used at the end of a lesson on recognizing angle measure as additive. The students will complete the activity Parker's Pizza. Students can complete this activity individually or with a partner. After the completion of the activity, the teacher will lead a class discussion allowing the students an opportunity to share their ideas on how to cut the pizza. 
Assessment Strategies:

The activity Parker's Pizza can be used to assess mastery of students' ability to recognize angle measurement as additive.
Advanced Preparation:

The teacher will need to make a copy of the Parker's Pizza activity and share it with the students in Google Classroom or share the link to the activity. If students do not have access to a device with Google Classroom or Docs, then the teacher can display the activity using a projector or print paper copies for each student.
Variation Tips (optional):

Parker's Pizza activity could be extended to increase the rigor. Students could problem-solve how to evenly share the pizza slice with three people or identify what portion of the entire pizza Parker brought home.  
Notes or Recommendations (optional):

This activity can be completed independently or with partners according to students' levels of ability.
