Students explain how satellites help scientists to see more than with the unaided eye and how Landsat technology works. Students identify vegetation and fire sites in the rainforest and detect erosion along rivers. They are able to use...

Students explore the concept of estimation. In this estimation lesson, students discuss making estimates through teacher led discussion. Students use the Internet to complete an activity where they must estimate the length of lines.

Learners pretend they are time-travellers and travel back to 1954 to a McDonald's Restaurant to see how prices have changed. They need to add and subtract money with regrouping.

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...

Learners view and discuss a video about the use of pattern block shapes to form pictures. They, in groups, form garden and quilt designs using pattern blocks and then decorate the room with their art.

Students consider an individual habit and its cost. They study ratios and proportions, and use that knowledge to calculate the cost of a habit over extended periods of time. write a detailed comparison of the costs.

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Learners examine how driving a hybrid car can save money and cut down on pollution.  In this hybrid vehicles lesson students complete an exercise that shows them how to work with proportions, percents, dimensional analysis and...

Students investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

For this know your fractions worksheet, students practice drawing a line from the portion of eight shapes to the appropriate fraction or whole number.

Students explore the concept of modular arithmetic and cryptography. For this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Students observe bird nests. In this observation level, students explore bird nests using their five senses. Students compare and contrast bird nests while hypothesizing about the need birds have to construct the nest.

First graders identify different coins and use their values in combination with each other to buy different objects. In this coins lesson plan, 1st graders identify the value of a quarter, dime, nickel, and penny, and use them to buy items.

Fifth graders explore fractions of whole numbers as they make fraction bead necklaces.

Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.

Students distinguish between proper and improper fractions. They create a "Character Clue Box" that represents a fraction. Fractions are picked from a hat and then groups go outside and search for items that represent their fraction....

Students sort a variety of manipulatives and use a software program that provides more sorting practice.

Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students explore inequalities. In this Algebra I instructional activity, students solve and graph linear inequalities involving addition, subtraction, multiplication, or division.  Students use inequalities to solve and graph...

Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.

Fifth graders explore real-life situations of area and perimeter. They develop a list of real-life applications of area and perimeter, select a situation, and write a step-by-step procedure and diagram on graph paper for solving the...

Fourth graders explore fractions. They compare different fractions using fraction bars. Students find equivalent fractions and they use fraction bars to visualize addition of fractions.

Students use physical models and graphs in order to solve problems that have their origin in the real world that require algebraic thinking. The words are changed into equations and inequalities in order to be solved. This requires...
