Partitioning Rectangles 2nd Grade | Rows, Columns & Arrays Activities

Make rows, columns, arrays, and partitioning rectangles easier for students to see and understand with this engaging 2nd grade math resource.

Designed around Common Core Math Standard 2.G.2, these activities help students learn how to partition rectangles into equal-sized squares, count the total number of squares, and describe their work using rows and columns. Students move from hands-on folding activities to guided practice, independent partitioning, task cards, and a collaborative project—building an important foundation for arrays, multiplication, and area models.

What’s Included

• Teacher notes and teaching suggestions
• Sentence frames for discussing rows, columns, and squares
• Hands-on folded-paper partitioning activity
• Counting squares practice
• Guided practice partitioning rectangles into rows and columns
• Practice with and without visual scaffolds
• Answer keys for practice pages
• Partitioning project using grid paper
• 24 partitioning rectangles task cards
• Task card recording sheet and answer key

Skills Covered

Students practice partitioning rectangles into equal squares, identifying and counting rows and columns, determining the total number of square units, and explaining the relationship between rows, columns, and the total number of squares.

These activities also provide meaningful early experience with arrays and area models, helping students develop visual models they can connect to multiplication concepts later.

Ways to Use This Resource

Use the activities during whole-group math instruction, small groups, independent practice, math centers, intervention, or review. The folded-paper activity provides a concrete introduction to equal-sized squares, while the practice pages gradually move students toward partitioning rectangles more independently.

The included project gives students an opportunity to create and label their own rectangles on grid paper. The 24 task cards are ideal for additional practice, centers, partner work, or early finishers and can be laminated for repeated use with dry-erase markers.

Support for Math Language

Sentence frames help students describe the number of rows, columns, and squares using complete sentences. This makes the resource especially useful when supporting students who are developing academic math vocabulary, including English learners.

Why Teachers Will Love It

This resource moves students from concrete, hands-on exploration to visual models and independent practice. Instead of simply counting squares on completed grids, students have opportunities to create, partition, label, count, and explain their own rectangular arrays.

The variety of activities also makes it easy to revisit the skill in different ways throughout your geometry or early multiplication instruction.

Build a Foundation for Arrays and Multiplication

Give your 2nd graders meaningful practice with partitioning rectangles, rows and columns, arrays, equal squares, and area models. These activities help students strengthen geometry skills while developing the visual understanding they will need for future multiplication work.
