Geometry & Measurement

3.GM.1Understand that quadrilaterals in different categories may share attributes; those attributes (e.g., four equivalent sides) can define a larger category (e.g., quadrilaterals) or subcategory (e.g., rhombus and square).3.GM.10Tell and write time to the nearest minute, using analog clocks.3.GM.11Solve word problems involving addition and subtraction of time intervals in minutes.3.GM.2Identify perpendicular and parallel lines, as well as right angles in two-dimensional shapes and real-world surroundings or objects.3.GM.3Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, identifying and/or drawing examples of quadrilaterals that do not belong to any of these subcategories.3.GM.4Measure lengths of objects to the nearest half and quarter inch, using a ruler.3.GM.5Describe area as the number of unit squares that cover a plane figure without gaps and overlaps.3.GM.6Find the area of a rectangle with whole number side lengths by modeling with unit squares and multiplying the side lengths to show the results are the same.3.GM.7Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real-world and mathematical problems.3.GM.8Measure and estimate liquid volumes and masses of objects using standard units.3.GM.9Solve one-step real-world problems involving liquid volumes and masses of objects in the same units, using all four operations.
