Collect and sort objects into categories and compare the categories by counting the objects in each category. Report the results verbally, with a written numeral or with drawings.


Examples


A bag containing 10 circles, triangles and rectangles can be sorted by shape and then each category can be counted and compared.

Clarifications


Clarification 1: Instruction focuses on supporting work in counting.

Clarification 2: Instruction includes geometric figures that can be categorized using their defining attributes. 

Clarification 3: Within this benchmark, it is not the expectation for students to construct formal representations or graphs on their own.

Purpose and Instructional Strategies

The purpose of this benchmark is to develop a foundation for statistical thinking, as well as providing a context to support the development of counting skills (MTR.5.1). 
  • Instruction reinforces the counting and comparing benchmarks within the Number Sense and Operations strand (MTR.5.1). 
  • Instruction reinforces the identifying and sorting of figures benchmarks within the Geometric Reasoning strand (MTR.5.1).

 

Common Misconceptions or Errors

  • Students may not clearly define categories for sorting objects which may lead to inaccurate data collection as objects fit into multiple categories. 
  • When students are presented with objects to be sorted into predefined categories, they may be frustrated that some objects don’t fit into any category.

 

Strategies to Support Tiered Instruction

  • Instruction includes opportunities to sort 3D shapes. Teacher places foam, wood and/or pattern blocks into a bucket. Students are asked to sort the blocks. The teacher will see how the students sort the blocks and ask the students to explain why they sorted the blocks a particular way (could be by color, size, texture etc.) If students are unsure of where to place a block, help them determine what category in which to place the block. 
    • For example, students will count how many blocks are in each of their groups and record the numeral. The teacher asks comparing questions about the groups such as “How are these shapes different from one another?” or “Are there more red shapes or blue shapes?” or “Are there more squares than triangles?” The teacher will then ask the students to sort the blocks another way and repeat the activity after the blocks have been classified a new way. 

                  Shapes are sorted by color             Shapes are sorted by type                 

  • Instruction provides opportunities to sort objects by attribute. 
    • For example, with school supplies, the teacher asks students to sort all the objects that can write in one group (pencils, crayons, markers etc.) and put all the objects that do not write in another (paper, white boards, tape etc.). Then, the teacher asks students to describe how the object fits that attribute. If students are having difficulty finding objects with that attribute, the teacher provides examples for them to follow. The students count the number of objects in each of their groups and record the numeral.

Instructional Tasks

Instructional Task 1 

Provide students with cards or objects that can be sorted multiple ways (i.e., shapes that are various colors and could be sorted by shape or color). In a group, give students time to think and discuss the various ways the cards or objects could be sorted. After a discussion, the group will decide a way to sort the cards or objects and do so. Then the teacher asks questions such as: “Which group has the most?” “Which group has the least?” “How many are in [fill in the blank] group”? After a discussion, the cards or objects can be resorted and the task can begin again. 

 

Instructional Task 2 

At the beginning of the task, ask students: 
  • Which shape appears the most? 
  • How many more triangles are there than circles? 
  • How many squares are there? 
  • How many figures have straight sides? 

 

Instructional Task 3 

Ask students to sort the figures into groups of circles, rectangles and triangles. 
Ask same or similar questions from Task 2A. 
Discuss how sorting makes answering the questions easier.

Instructional Items

Instructional Item 1 

Part A. Students can sort themselves based on given attributes (eye color, shirt color, method of transportation to or from school, etc.). 
Part B. Have students report their sorting using a drawing.

 

Instructional Item 2 

Part A. Circle the buttons that are shaped like triangles. 
Part B. How many buttons are shaped like a triangle? 

buttons shaped like triangles

Shape Sort

Students sort shapes into categories, record their categories and frequencies, and identify the categories with the most and least.

Sorting Buttons

Students sort illustrations of buttons, explain the how and why, and count the number in each group.

Sort the Tiles

Students sort tiles by color and then count to determine the group with the most and the least number of tiles.

Sorting Color Tiles

Students sort objects by type and then identify which group of objects has the most and the least.

Lesson Plans

Name Description
Tell Me About Your Stuffed Animal (Lesson 3)

In this integrated lesson, students will work as a class to categorize and sort stuffed animals by physical attributes.  They will then work in groups to categorize and sort shapes.

Birds of a Feather

Students will go on a simulated bird-watching trip around the classroom.  They will collect and sort images of various birds into categories based on their visible characteristics.  They will use these groups of bird images to practice counting and comparing objects in different categories.  Students will use descriptions of bald eagles in the book, The Bald Eagle by Norman Pearl, to identify images of bald eagles among their categories and discuss how the bald eagle is a symbol of the United States.

 

Sorting and Saying Through Voting

Students will have the opportunity to apply knowledge of sorting and responsible voting to a fun and collaborative small group activity in this integrated lesson plan.

Students will identify the American flag as an important symbol of the United States. They will collect and sort data from the American Flag and compare the attributes. Students will sort and count red stripes and white stripes, long stripes and short stripes, long red stripes and long white stripes, short red stripes and short white stripes. Students will compare the stripes using the number line. They will also count stars by 1’s and 10’s in this integrated lesson plan.

Whose Baby is That?

This inquiry-based 5E lesson provides an initial look at categorizing items into 2 categories. Visuals of animals are used to begin the classifying/categorizing of animals and their babies. Students will practice categorizing in pairs and will be given the categories to use. They will then explain the placement of each item in the category. The teacher will ask guiding questions and facilitate the lesson to ensure comprehension of the material.
