Students estimate the numbers of objects in situations in which counting is not feasible or necessary.

Students will use their knowledge or availability and scarcity to determine income and earnings.

STUDENT ACTIVITY -- 5th -- NC/TXThis is a distance-learning lesson students can complete at home. The student will use their knowledge of operations (addition and subtraction) of fractions with unequal denominators to solve real world problems.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.

Students will be able to describe the shares using the words halves and fourths. They'll be able to describe the whole as two of, or four of the shares.

STUDENT ACTIVITY - 5th - TXStudents will use their knowledge of fractions to divide whole numbers

Students will use their knowledge of geometric shapes to find real world examples outdoors.

STUDENT ACTIVITY - 3rd - GA/TXThis is a distance-learning lesson students can complete at home. Students will measure plants and create bar graphs to compare data to actual mature plant heights.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.

Students measure and analyze forces that act on vehicles pulling heavy objects while moving at a constant speed on a frictional surface. They study how the cars interact with their environments through forces, and discover which parameters in the design of the cars and environments could be altered to improve vehicles' pulling power. This LEGO® MINDSTORMS® based activity is geared towards, but not limited to, physics students.

In this lesson, students will choose a feature in the outdoor classroom to measure using a selected tool (tape, ruler, or yard/meter stick). They will sketch feature and label its dimensions.

In this lesson, students will develop fluency for splitting numbers into tens and ones by applying the concept to the concrete example of leaves on plants.

This lesson will require students to practice measuring real-world objects in different units and evaluate the most effective units to use for solving problems.

Students will identify which unit of measure inch, foot or yard is best for measuring various items in the outdoor learning lab. They will then apply the use of the appropriate tool to measure a variety of objects to the nearest marker.

In this lesson, students will build fluency using the language of measurement by collecting data about various plants in the outdoor classroom.

In this lesson, students to practice measuring real-world objects in different units and evaluate which are the most effective units for solving particular problems.

Students will use leaves to measure different plants in and around the garden.

In this lesson, students will measure spaces in the outdoor classroom in metric units recorded as decimals and compare the measurements.

Students learn about two-axis rotations, and specifically how to rotate objects both physically and mentally about two axes. A two-axis rotation is a rotation of an object about a combination of x, y or z-axes, as opposed to a single-axis rotation, which is about a single x, y or z-axis. Students practice drawing two-axis rotations through an exercise using simple cube blocks to create shapes, and then drawing on triangle-dot paper the shapes from various x-, y- and z-axis rotation perspectives. They use the right-hand rule to explore the rotations of objects. A worksheet is provided. This activity is part of a multi-activity series towards improving spatial visualization skills. At activity end, students re-take the 12-question quiz they took in the associated lesson (before conducting four associated activities) to measure how their spatial visualizations skills improved.

In this, students will be able to demonstrate the ability to use a variety of non-standard units of measurements to measure the length of different objects around the outdoor classroom.

Student groups work with manipulatives—pencils and trays—to maximize various quantities of a system. They work through three linear optimization problems, each with different constraints. After arriving at a solution, they construct mathematical arguments for why their solutions are the best ones before attempting to maximize a different quantity. To conclude, students think of real-world and engineering space optimization examples—a frequently encountered situation in which the limitation is the amount of space available. It is suggested that students conduct this activity before the associated lesson, Linear Programming, although either order is acceptable.
