Sixth graders, in groups, are given different parts of the whole project. They use information from Busch Gardens to explore line graphs, averages, and other math vocabulary.

Fourth graders estimate the measurements of trees using unconventional techniques.

Students are given a brown paper sack filled with different types of object for them to measure. They are to first estimate the length and then measure them in centimeters and millimeters.

Students make an inquiry with the aid of technology into the concept of functions. The emphasis of the lesson plan is on the interplay between the geometric and analytic information.

Students work with dominoes to recognize the number of spots on each side as they relate to addition facts. In this seeing doubles activity, students make triangle shaped flash cards for the double facts. Students represent the correct...

Fourth graders play an estimation game to guess how sheets of paper are in a pile and then guess who high a stack of one million would be. They work in small groups to explore ideas for working out how high the stack would be.

In this number sense worksheet, 1st graders work with a partner to practice skills of estimation. Students use a cup and beans to estimate the amount of beans that come out of the cup before completing an accurate count each turn.

In this estimating to check results reteaching worksheet, 1st graders examine how to use estimation to check their addition. They apply the steps to solve and check 2 word problems.

Students explore the concept of measuring length using a one-inch pipe cleaner "inchworm." They listen to the story "Inch By Inch by Leo Lionni and discuss how the animals were measured by the inchworm in the book. In pairs students...

Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.

Young learners apply divisibility rules to determine if a number is a factor of another number. They discuss what numbers are factors of another number and identify patterns using divisibility rules.

Students discover the actual size and weight of many insects and animals. In this biology lesson, students investigate animals and insects to determine their actual weight and size. In groups, students create an animal or insect of their...

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Learners observe and sort tree leaves. In this plant biology lesson, students observe various types of leaves and identify the characteristics of each leaf. Learners measure and sort leaves according to size and color.

Learners examine the change in the diversity of animals living in an area before and after development. In order to do this, students need to have access to an area near their school which is undeveloped. A good, "real life" lesson plan.

Students student the concept of bycatch, the act of unintentionally catching certain living creatures using fishing equipment. They determine the difference between bycatch and target creatures. They discover what species become bycatch...

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture.
