By the end of second grade, students understand place value and number relationships as they add and subtract and they use simple concepts of multiplication. They measure quantities with appropriate units. They classify and see relationships among shapes by paying attention to the elements that compose them. Students use estimation strategies in computation and problem solving that involve numbers that use the ones, tens, hundreds and thousands places. Students demonstrate an understanding of patterns and how they grow, and describe them in general ways.
Students note the connections between one problem and another.
The study of contemporary people who supply goods and services aids in understanding the complex interdependence in our free-market system. 2.1 Students differentiate between things that happened long ago and things that happened yesterday.

Label from memory a simple map of the North American continent, including the countries, oceans, Great Lakes, major rivers, and mountain ranges.
