## Measurement and Data Stations

**Kindergarten**- Students describe measurable attributes of objects, such as length and weight. They compare two objects that have a measurable attribute in common, identifying which object has "more" or "less" of the attribute. They begin to classify objects and count the number of objects in each category.

**First Grade**- Students measure lengths indirectly and by iterating length units, such as by laying cubes end to end and counting the number of cubes, and they learn to order three objects by length. First graders begin to learn about time, telling and writing time to the hour and half-hour on digital and analog clocks. They also organize, represent, and interpret data with up to three categories and and ask and answer questions about the data.

**Second Grade**- Students in second grade measure and estimate lengths in standard units. Students connect their work with a ruler to their work with a number line and relate addition and subtraction to length. They learn to write and tell time to the nearest five minutes on analog and digital clocks, and they solve word problems dealing with money. (In second grade money is either in cents or dollars without using a decimal point.) Second graders also generate measurement data and graph it. They draw picture and bar graphs (with single-unit scale) to represent data sets with up to four categories, and they solve addition and subtraction word problems using information presented in a bar graph.
