Describe and compare measurable attributes of objects (Standards K.MD.1-2) and classify objects and count the number of objects in each category (Standard K.MD.3).

Standard K.MD.3

Classify objects into given categories; count the numbers of objects in each category and sort the categories by count. Limit the category counts to less than or equal to 10.

  • Georgia Standards of Excellence Mathematics
    GeorgiaStandards.Org (GSO) is a free, public website providing information and resources necessary to help meet the educational needs of students. The goal of this web site is to provide information that will enhance and support teaching and learning of Georgia standards.
  • Goodie Bags
    In this task students compare 3 quantities and order them from least to greatest using various items.
  • IXL Game: Sorting, ordering, and classifying: Put numbers up to 30 in order
    This game helps the kindergartener classify objects into given categories. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use.
  • Kindergarten Mathematics (Engage NY)
    In order to assist educators with the implementation of the Common Core, the New York State Education Department provides curricular modules in Pre-K-Grade 12 English Language Arts and Mathematics that schools and districts can adopt or adapt for local purposes.
  • Kindergarten Unit 1: Counting With Friends (Georgia Standards)
    In this unit, students will recognize and order numbers 0-20, count to tell the number of objects (to 20), compare numbers (to 10), and write the numbers 0-20.
  • Kindergarten Unit 2: Comparing Numbers (Georgia Standards)
    For numbers 11 to19, Kindergarten students choose, combine, and apply strategies for answering quantitative questions. This includes composing and decomposing numbers from 11 to 19 into ten ones and some further ones by writing and representing the numbers, counting and producing sets of given sizes, counting the number of objects in combined sets, or counting the number of objects that remain in a set after some are taken away. Objects, pictures, actions, and explanations are used to solve problems and represent thinking.
  • Kindergarten Unit 3: Sophisticated Shapes (Georgia Standards)
    Students describe their physical world using geometric ideas (e.g., shape, orientation, spatial relations) and vocabulary. They identify, name, and describe basic two-dimensional shapes, such as squares, triangles, circles, rectangles, and hexagons, presented in a variety of ways (e.g., with different sizes and orientations), as well as three-dimensional shapes such as cubes, cones, cylinders, and spheres. They use basic shapes and spatial reasoning to model objects in their environment and to construct more complex shapes.
  • Kindergarten Unit 4: Measuring and Analyzing Data (Georgia Standards)
    In this unit, students will describe and compare measurable attributes, classify objects and count the number of objects in each category.
  • Measurement and Data (K.MD) - Kindergarten Core Guide
    The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Kindergarten Mathematics - Measurement and Data (K.MD)
  • Sort and Count I
    Using cards or various objects students must look at the items and decide two or three different ways to sort them.
  • Sort and Count II
    The purpose of this task is for students to sort the same set of objects according to different attributes and to practice counting to tell the number of objects in a set.
