TX. 111.4. Grade 2, Adopted 2012.
2.8. Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:
2.8 (B) 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.
2.8 (C) Classify and sort polygons with 12 or fewer sides according to attributes, including identifying the number of sides and number of vertices.
2.8 (D) Compose two-dimensional shapes and three-dimensional solids with given properties or attributes.
2.9. Geometry and measurement. The student applies mathematical process standards to select and use units to describe length, area, and time. The student is expected to:
2.9 (D) Determine the length of an object to the nearest marked unit using rulers, yardsticks, meter sticks, or measuring tapes.
2.10. Data analysis. The student applies mathematical process standards to organize data to make it useful for interpreting information and solving problems. The student is expected to:
2.10 (A) Explain that the length of a bar in a bar graph or the number of pictures in a pictograph represents the number of data points for a given category.
2.10 (C) Write and solve one-step word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one.
2.10 (D) Draw conclusions and make predictions from information in a graph.
