### Gettysburg by the Numbers (GBTN) and Common Core

GBTN provides opportunities to address several Common Core standards listed below. In addition, GBTN offers extensions for students to research questions offered at the end of each topic detail, thus gaining experience both reading and writing informational texts. Some questions also require mathematical computations, estimates, and problem solving.

Literacy in the Social Studies:
CCSS.ELA-Literacy.RH.6-8.7 (Grades 6-8) Integrate visual information (e.g., in charts, graphs, photographs, videos, or maps) with other information in print and digital texts.
CCSS.ELA-Literacy.RI.6.7  (Grade 6) Integrate information presented in different media or formats (e.g., visually, quantitatively) as well as in words to develop a coherent understanding of a topic or issue.

Gettysburg by the Numbers builds personal experience with exactly what the standards specify: visual information to integrate knowledge about the turning point of the Civil War.

Math:
CCSS.Math.Content.6.RP.A.1 (Grade 6) Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

CCSS.Math.Content.6.RP.A.3  (Grade 6) Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

CCSS.Math.Content.7.RP.A.2 (Grade 7) Recognize and represent proportional relationships between quantities.
