| First Grade Mathematics|
In first grade children increase their knowledge of patterns, shapes, and estimation. They learn to recognize additional two-dimensional shapes (e.g., rhombus, ellipse) and also learn to recognize and name three-dimensional objects (e.g., cube, cylinder, sphere, cone, and pyramid). Children learn to identify objects that have line symmetry. Using standard units, they begin to measure length. Children collect, organize, and display data, extending their experience with graphs and tables. They begin to use place value and to add and subtract without regrouping. Simple fractions such as 1/2, 1/3, and 1/4 are introduced. Children extend their knowledge of money and time. They learn to work with number sentences involving variables (e.g., ? + 7 = 12).
