Computer Tools for Logic, Information, Graphing, and Data Analysis
How can students learn to make sense of data and manage today's increasing amounts of information? In doing activities supported by Tabletop and Tabletop Junior, students can develop skills fundamental for data analysis and essential for literacy in an information age. These data tools offer a new way to interact with data and information. Tabletop and Tabletop Junior animate data to create engaging visual environments and give students analytical power they can use to think critically. With both, students categorize and measure, organize and arrange, represent and interpret, and graph and analyze.

Tabletop -- Grades 4 to 12
Tabletop is designed for mathematics, science, social studies (in fact, for any subject in which students might want to explore or analyze data.) Students use Tabletop to work with existing databases or with databases they create themselves. Tabletop represents data as mobile icons that can arrange themselves into such forms as box plots, crosstabulations, histograms, scatter plots, and Venn diagrams, under the students' control. This capability, coupled with options for labeling and marking groups of icons or performing summary computations, allows students to view the same data in different ways.

Tabletop Junior -- Grades K to 6
Tabletop Junior offers young students an introduction to the mathematics of data and information and provides a rich domain for building language skills. With Tabletop Junior, students make and arrange different objects such as pizzas, stick figures, clocks, party hats, and attribute "blocks." Built by combining simple attributes, these objects can either stand for themselves or be used to represent numerical and categorical data. Students can make free-form arrangements of the objects manually or they can have the objects arrange themselves automatically into loops (Venn diagrams), bunches, stacks (pict-o-graphs), grids, and graphs.

Curriculum activities function as single pieces or as parts of open-ended investigations. Students compare bedtimes, measure and analyze hand and glove sizes, compose stories with stick figures, and play games like bingo and concentration.
