การจัดเรียงรูปทรง แผ่นงานสำหรับ ชั้นประถมศึกษาปีที่ 2

Give students a mixed set of 2D shapes and 3D solids, then agree on a precise sorting rule before placing anything. Follow with questions such as, “Could this shape belong in both groups?” to develop flexible classification rather than simple visual matching.

Second graders benefit from sorting by number of sides, vertices, or faces; correcting an incorrectly sorted example; and writing a rule that describes an existing group. Include shapes of different sizes and orientations so students must attend to structure.

Students may mix up sides, vertices, and faces, or group shapes by how they look instead of their defining attributes. Another common error is assuming categories cannot overlap. A square, for example, can satisfy a broader rule for four-sided shapes.

Use the worksheet as a digital quiz on Wayground for a quick formative check, or provide the printable PDF for classwork or intervention. Every worksheet includes a complete answer key; printed work can be scanned and graded with the Wayground for Teachers app.

Common Core Grade 2 geometry emphasizes recognizing and drawing shapes with specified attributes, including a given number of angles or equal faces. Sorting shapes by those properties prepares students to organize quadrilaterals more precisely and reason about how shape categories relate.

Provide larger text or wider spacing for students who find crowded shape sets difficult to scan. In digital practice, reduce answer choices for targeted support; for enrichment, ask students to create a second valid sorting rule for the same collection.

By Grade 2, students should be able to identify common 2D and 3D shapes and sort them using properties such as sides, vertices, angles, and faces. They should also be able to state the rule used for a category.
