All of the following describe developmentally appropriate math activities for kindergartners EXCEPT

• A. Counting objects
• B. Worksheets on which children can practice addition and subtraction problems
• C. Sorting by attributes
• D. Using manipulatives to explore number concepts

Answer: (B)

Kindergarten math should be rooted in concrete, hands-on experiences that build number sense. Counting objects supports one-to-one counting and linking number words to quantities, which is essential at this age. Sorting by attributes helps children notice patterns, classify, and compare groups, laying the groundwork for logical thinking. Using manipulatives to explore number concepts keeps learning tangible—children can physically move items to see how numbers relate, understand part-whole ideas, and practice counting in a meaningful way. In contrast, worksheets that practice addition and subtraction tend to be too abstract for many kindergartners, requiring symbol-slinging and rapid recall before students have had ample concrete experiences with combining quantities. Instead, arithmetic ideas are introduced through guided play, manipulatives, number lines, and story-based contexts. So the activity described as addition and subtraction worksheets is not developmentally appropriate for kindergartners.
