Mathematics Kindergarten

Strand: MEASUREMENT AND DATA (K.MD)

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.

• 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.
• 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.
• USBE Core Guide for Domain: Measurement and Data (KMD3)
This math guide provides academic vocabulary, instructional strategies, teacher resources, and assessment tasks for the Measurement and Data domain.
• Unit 1: Counting With Friends
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.
• Unit 2: Comparing Numbers
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.
• Unit 3: Sophisticated Shapes
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.
• Unit 4: Measuring and Analyzing Data
In this unit, students will describe and compare measurable attributes, classify objects and count the number of objects in each category.
