        This lesson is designed to support student understanding of three-dimensional solids


        The two instructional blocks in this lesson focus on identifying parts of a 3D shape and identifying 3D shapes based on their parts. 


        In the first instructional block, students learn the different parts of a 3D shape such as face, edge and vertices.


        The second instructional block focuses on how to identify a 3D shape based on their parts.


        Scaffolds and supports such as pictorial representations of 3D shapes are intentionally built throughout the lesson to support conceptual learning.

      Frequently Asked Questions

      How do you teach Classify and Sort 3D Figures to 2nd graders?

      To teach Classify and Sort 3D Figures to 2nd grade Math students, start with concrete, hands-on models, then move to pictorial representations before abstract notation. TEKS 2.8B asks students to classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language. Crystal Instruction's free ClearLessons for 2.8B walk through this progression with modeling, guided practice, and built-in checks for understanding, while the ClearSheets provide scaffolded practice. You can download both free on this page.

      What is 2.8B in 2nd grade Math?

      TEKS 2.8B is a 2nd grade Math standard for Classify and Sort 3D Figures. It requires students to classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language. It is part of the Texas Essential Knowledge and Skills (TEKS) for Grade 2 Math.

      Where can I find free TEKS 2.8B lessons and worksheets?

      You can download free TEKS 2.8B lessons and worksheets directly on this page — no login or account required. Crystal Instruction provides free PDF versions of our Classify and Sort 3D Figures ClearLessons and ClearSheets for Grade 2 Math, and each one is also available as an interactive lesson inside the full Crystal Instruction platform.

      What skills are included in 2nd grade Classify and Sort 3D Figures?

      TEKS 2.8B (Classify and Sort 3D Figures) covers the following 2nd grade Math skills: students learn to classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language. Free resources for this standard include Classify and Sort Three-Dimensional Shapes.

      Are TEKS 2.8B resources aligned to STAAR?

      Although Grade 2 Math is not directly tested on the Texas STAAR test, TEKS 2.8B builds the foundational skills students need for later STAAR assessments. Every Crystal Instruction ClearSheet for 2.8B is STAAR-aligned, and our ClearLessons are built to STAAR rigor using released STAAR test items, so students practice Classify and Sort 3D Figures at the depth STAAR expects.
