How many trees can your pupils plant? Practice numbers 0-20 with several related activities. For the first, kids match images of trees to numbers. They then match the number symbols to number words, using a word bank. The final activity...

Take a tiered approach to studying waste. The lesson uses Earth Day to present differentiated instruction around using circle and bar graphs. Each group gets a cube based on their tiers and works collaboratively as well as individually...

Math and M&Ms® go great together when introducing a modeling activity. Allow your learners to simulate population growth and decay of fish in a pond and share their reasoning for the change in fish. With such an impact we have on our...

Is there a correlation between a country's wealth and the extent of its ecological footprint? What exactly constitutes an ecological footprint, and how does one country stack up against the rest? This is a unique lesson to incorporate...

Where does our garbage go? What is the difference between a recyclable and non-recyclable item? Pose these important, but often overlooked, questions to your class and invite them to consider the lasting and damaging effects of the...

Take some time this Earth Day to nourish the growth of your young mathematicians with this series of task cards. Whether it's the four basic operations, place value, money, or elapsed time, these conservation-themed problems...

In this Earth Day activity worksheet, students use their problem solving skills to help Earth get back to the proper orbit by leading it through the maze.

Build up from the previous activity where your learners charted the population growth and decay of a fish pond with M&Ms®. Have them look at the data from that activity and create a Now-Next, or recursive equations, to predict the...

With so many tons of trash going into landfills each year, your environmentalists can calculate how much the average person is tossing away. This activity has a series of questions not only requiring math, but a conscious thought of how...

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

Youngsters learn how "hand-me-downs" can help save money while practicing math word problems with this fun learning center activity.

Students participate in local Earth Day activities. They keep track of the types of trash they pick up. They aggregate their data to develop whole-class statistics of what they found.

Do your young mathematicians recognize the recycle sign? Learners fill in the blank circles inside the recycle sign with the arrows, pointing to the next number in the sequence, with the correct inequality sign or equal sign to make the...

The key to solving this puzzle lies in the addition skills of young learners. The first step is to answer a series of decimal addition problems organized in a 4x5 grid. Then cut apart the page of puzzle pieces, each one including an...

Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Why do shadows look different in the summer than in the winter? What causes day and night? How can a sundial be used to tell time? Answer these questions and more through two engaging lessons about light and shadows. Fourth and fifth...

In this Earth Day counting worksheet, students count trees and either circle or color the number counted: 3, 4, 5 or 6. A reference web site for additional activities is given.

In this Earth Day counting learning exercise, students count a set of recycle bins and circle the number counted, choosing from 10, 11 or 12. A reference web site for additional activities is given.

Students explore air pollution. For this ecology lesson, students participate in an experiment in which 5 numbered jar lids are placed outside. Students bring one lid a day in until all jars are inside. Dirt specks are counted, observed,...

Students use principles of geometry to measure the circumference of the Earth. In this applied geometry lesson, students use mathematics to determine scientific information. They make measurements, calculate the central angle, and...

Why is the weather man wrong so often? Young climatologists discover how chaos rules both weather and climate through a math-based activity. Using an iterative equation, the class examines how small day-to-day weather events total up to...

Middle schoolers become aware of the effects of tides on the Earth's rotation. For this tides lesson, students calculate the number of seconds lost over various periods of time.

Students examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.
