Shape up to Geometry There are six 3-D shapes we need to know * There are six 3-D shapes we need to know: cone, cube, cylinder, rectangular prism, pyramid, and sphere. A line of symmetry meansA line of symmetry means : both sides of a figure are the same size when a line is drawn down the middle. We can combine shapes to make new shapes * We can combine shapes to make new shapes. http://www.ixl.com/math/practice/grade-2 http://www.mcrel.org/topics/products/16
