STUDENT ACTIVITY - 4th - TXThis is a distance-learning lesson students can complete at home. The student will use their knowledge of parallel and perpendicular lines to compare those that are man-made and others found in nature. 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.

A web page and interactive applet showing the definition and properties of a parallelogram. The applet shows a parallelogram where the user can drag any vertex. The other points then move in such a way that the figure remains a parallelogram at all times. A control to hide the details allows a classroom discussion where students can try to infer what the properties are as it is reshaped by the discussion leader. Text on the page has the formal definition and properties of the parallelogram with links to related pages. A companion page is http://www.mathopenref.com/parallelogramarea.html showing the ways to calculate the area of a parallelogram Applet can be enlarged to full screen size for use with a classroom projector.

Pearl Diver is a fun, interactive web-based game and app for iPad and iPhone. Players learn the number line while diving for pearls amidst shipwrecks and sunken ruins. This learning game addresses standard mathematic concepts included in the current Common Core curriculum such as:
-understanding numbers, ways of representing numbers, and number systems
-understanding and representing commonly used fractions
-understanding fractions as part of unit wholes and as locations on number lines
-comparing and ordering fractions, and finding their approximate locations on the number line
Pearl Diver is supported by supplementary materials including teacher’s guide, learner’s guide, “Teaching With Pearl Diver” video, and printable resources. It is available in English and Spanish. This game is available free on the Apple App Store.
This project was sponsored by NSF and developed by the Learning Games Lab in collaboration with researchers and mathematicians in the College of Education and College of Arts and Sciences at New Mexico State University.

Navigate the number line while diving amidst shipwrecks and sunken ruins. Will you find a pearl, or an old boot? Watch out for the electric eel! Pearl Diver teaches properties of numbers, how to plot numbers, how to visualize quantity on the number line, how to order numbers, and how to use the number line as a visual model for mathematical operations.

A web page and interactive applet show how to compute the perimeter of a polygon. A polygon is shown that can be resized by dragging its vertices. As you drag, the perimeter is continuously recalculated. Text on the page explains that the perimeter is the sum of the sides. For those who prefer it, in a formula that is given. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference interactive geometry reference book project at http://www.mathopenref.com.

In this lesson the students will use their knowledge of measurement to determine perimeter and find missing lengths when given the total perimeter.

In this lesson the students will use their knowledge of measurement to determine perimeter. Since this is a virtual lesson for at home learning, steps will be included for students to make an 8 inch paper ruler out of notebook paper.

An interactive applet and associated web page that show how to determine of one line is perpendicular to another in coordinate geometry. The principle used is that if two lines a re perpendicular to each other the slope of one is the negative reciprocal of the other. The applet shows to lines that the user can move. The slopes are continuously calculated as you drag them, and if the they are parallel they change color. The calculation is shown on screen updated continuously as you drag. The grid, axis pointers and coordinates can be turned on and off. The calculation display can be turned off to permit class exercises and then turned back on the verify the answers. The applet can be printed as it appears on the screen to make handouts. The web page has a full description of the concept of perpendicularity, a worked example and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

This interactive Flash animation allows students to explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement. In the simplest level, users estimate the number of small line segments that can fit into a larger line segment. Intermediate and advanced levels offer feature games that explore area of rectangles and circles, and volume of spheres and cubes. Related lesson plans and student guides are available for middle school and high school classroom instruction. Editor's Note: When the linear dimensions of an object change by some factor, its area and volume change disproportionately: area in proportion to the square of the factor and volume in proportion to its cube. This concept is the subject of entrenched misconception among many adults. This game-like simulation allows kids to use spatial reasoning, rather than formulas, to construct geometric sense of area and volume. This is part of a larger collection developed by the Physics Education Technology project (PhET).

Students are introduced to the physics concepts of air resistance and launch angle as they apply to catapults. This includes the basic concepts of position, velocity and acceleration and their relationships to one another. They use algebra to solve for one variable given two variables.

In this lesson students will use their knowledge of decimals to solve problems in a real- world setting.

This article highlights lessons and activities that ask students to plan expeditions to Antarctica. Students use math, science, and geography to plan their routes, clothing, and food.

STUDENT ACTIVITY - 4th - NCThis is a distance-learning lesson students can complete at home. The student will explore and record data about different plants that they observe. Then they will create a bar graph to reflect the data that that they collected. 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.

In this lesson, students will explore and record data about different plants that they observe. Students will then create a bar graph to reflect the data that that they collected. For example, a student might find 7 tomato plants, 5 cabbages, and 4 squash plants; their graph would reflect these numbers.

The Playful Learning Challenge's Pre-K and Kindergarten Math Activities Kit contains a series of 10 research-based early math activities centered around play, that can be used with simple materials in children's classrooms or homes.

The students will play a classic game from a popular show. Through this they will see the probabilty that the ball will land each of the numbers with more accurate results coming from repeated testing.

An interactive applet and associated web page that demonstrate polygons. The applet shows a polygon which is initially an irregular convex pentagon. The user can drag any vertex and a message shows if it becomes concave. The user can also alter the number of sides from 3 to 99, the title changing to reflect it's name up to 12 sides. You can also make it regular, dragging a vertex then changes all vertices to maintain it as regular. The web page has many definitions and links to the various forms and orders of polygon. Applet can be enlarged to full screen size for use with a classroom projector.
