This week in my third grade class, I introduced:

Monday: line, line segment, ray, angle, parallel lines, intersecting lines, right angle, and perpendicular lines.

Tuesday:Triangles--equilateral, isosceles, right, scalene

Wednesday: plane figures(triangle, square, rectangle, pentagon, hexagon, octagon) and regular and irregular polygons.

OK, I know the math series is simply a tool---but how many teachers do not supplement, explore through manipulatives or spend more than 1 day on a lesson? Such important concepts that the students will need throughout their education, and they are "lumped" together and given one page in the math text.
