This field trip was designed to supplement Mining Week in Nevada. It is meant for 3rd grade, but can be easily adapted for grades 1-5.Coming from a boom town, mining is a huge part of our community. At least half of my students each year have one or both parents working at the gold mines. We used to take students on field trips to the various mine sites, but they have since been banned for safety reasons. A virtual field trip is the next best thing!

## Common Core State Standards

3.MD.5 Recognize area as an attribute of plane figures and understand concepts of area measurement.

3.MD.7 Relate area to the operations of multiplication and addition.

a. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

b. Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

3.MD.3 Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add,subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.

3.OA.8 Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

3.RI.1 Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers

3.RI.4 Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area.

3.RI.5 Use text features and search tools (e.g., key words, sidebars, hyperlinks) to locate information relevant to a given topic efficiently

3.RI.9 Compare and contrast the most important points and key details presented in two texts on the same topic.

3.W.2 Write informative/explanatory texts to examine a topic and convey ideas and information clearly.

a. Introduce a topic and group related information together; include illustrations when useful to aiding comprehension.

b. Develop the topic with facts, definitions, and details.

c. Use linking words and phrases (e.g., also, another, and, more, but) to connect ideas within categories of information.

d. Provide a concluding statement or section.

3.W.7 Conduct short research projects that build knowledge about a topic.

3.W.8 Recall information from experiences or gather information from print and digital sources; take brief notes on sources and sort evidence into

provided categories

3.SL.2 Determine the main ideas and supporting details of a text read aloud or information presented in diverse media and formats, including visually, quantitatively, and orally.

3.SL.4 Report on a topic or text, tell a story, or recount an experience with appropriate facts and relevant, descriptive details, speaking clearly at an

understandable pace.

3.SL.6 Speak in complete sentences when appropriate to task and situation in order to provide requested detail or clarification.
