What's Inside

This 3-page PDF contains 12 problems. Students analyze base ten blocks, then write the number in expanded and standard form. The clean layout provides work space, and a separate answer key makes review easy.

A Progression to Mastery

This resource supports a gradual release model. Use the first page for guided 'We Do' practice, establishing the task routine. The second page works well for partner practice or math centers, allowing students to build confidence together. The final page serves as an independent 'You Do' assessment, perfect for checking individual comprehension or for a homework assignment. This progression moves students from guided learning to autonomous application.

Standards Alignment

This worksheet is directly aligned with CCSS.MATH.CONTENT.2.NBT.A.3, which requires students to read and write numbers up to 1000 using expanded form. It also supports CCSS.MATH.CONTENT.2.NBT.A.1 by reinforcing the concept that digits represent amounts of hundreds, tens, and ones. Both standard codes can be copied into lesson plans.

How to Use It

Use this worksheet for formative assessment after a place value lesson, or as a station activity during math centers. It is designed to take approximately 15-20 minutes. As students work, watch for reversals or difficulty with zeros as a diagnostic check on their understanding.

Who It's For

This resource is ideal for Grade 2 students. To support learners, provide physical base ten blocks. For an extension, challenge students to write the number names in words. It pairs well with a classroom place value anchor chart.

This worksheet provides focused practice on CCSS.MATH.CONTENT.2.NBT.A.3, a foundational standard for Grade 2 mathematics. By asking students to read and write numbers using base-ten numerals and expanded form, the activity directly builds number sense and an understanding of the base-ten system. Research consistently shows that a deep conceptual grasp of place value is a critical predictor of future success in mathematics, particularly with multi-digit computation and fractions. According to a RAND AIRS 2024 analysis on effective math instruction, materials that connect concrete representations (like base ten blocks) to abstract numerical forms are highly effective at building this crucial understanding. This resource operationalizes that best practice, providing the repetitive, structured exercise needed for students to internalize how three-digit numbers are composed of hundreds, tens, and ones, preparing them for more complex mathematical reasoning.
