Mystery Digits

Mystery Digits gives students focused practice identifying the place and actual value of a specific underlined digit in a decimal number. Students examine each decimal, name the digit’s position, and then write what that digit is worth. The worksheet strengthens tenths, hundredths, thousandths, ones, digit value, decimal notation, and place-value reasoning. It is especially appropriate for students in grades 4-6 who can read decimals but still confuse the name of a place with the value of the digit in that place.

Key Learning Objectives

• Locate the underlined digit: Students identify which digit is being tested.
• Name the place: Learners decide whether it is in the ones, tenths, hundredths, or thousandths place.
• Write the value: Students convert the digit and its position into an actual amount.
• Distinguish place from value: Children learn that “hundredths” is the place, while 0.06 may be the value.

Teaching Advantages

• Targets a common confusion: Students often know the place name but forget to write the digit’s true value.
• Supports parent guidance: Adults can ask two separate questions: “What place?” and “What value?”
• Builds precision: Learners must pay attention to every digit and its position.
• Works in many settings: Use it for review, homework, tutoring, math centers, or homeschool practice.
• Ready to use: No additional preparation or materials are needed.

The place of a digit and the value of a digit are related, but they are not the same answer. In 3.726, the 2 is in the hundredths place, but its value is 0.02. Making that distinction clear helps students understand decimals much more deeply. As learners complete the page, they strengthen place-value language, decimal fluency, number interpretation, mathematical precision, and confidence. In classroom and homeschool settings, this worksheet gives students the careful practice they need before working with expanded form, rounding, and comparison.
