Standard: K.CC.A3 – Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
Grade level: Kindergarten
Subject: Mathematics
Domain: Counting & Cardinality
Teacher Overview
This standard focuses on helping students write numbers from 0 to 20 and represent quantities with those numbers. It’s a foundational skill that supports future mathematical concepts like addition, subtraction, and place value. Students should already understand basic counting and the concept of quantity before tackling this standard.
After mastering this standard, students will be ready to learn basic addition and subtraction, understand place value, and compare numbers.
Common Misconception 1
Some students might think that the number 0 represents something rather than nothing. This is incorrect because 0 is used to indicate the absence of any objects.
Intervention 1
To remediate this misconception, teachers can use visual aids and examples of empty sets to show that 0 means no objects are present.
Common Misconception 2
Another common misconception is writing numbers backwards or in the wrong sequence. This can be due to a lack of familiarity with the number forms.
Intervention 2
Teachers can provide additional practice with number tracing and sequencing activities to help students become more familiar with the correct forms and order of numbers.
Prerequisite Knowledge
