Students recognize that counting tells how many objects are in the set irrespective of how they are arranged or the order in which they are counted. They solve problems involving one more or less to a given set using their knowledge of...

First graders share the story "Ten in the Bed". They rewrite the story so that the initial character is calling others to bed. There was one in the bed and the little one said, "Come to bed, come to bed." There were two in the bed and...

Fifth graders find pairs of whole number co-ordinates and use them to draw graphs in problem contexts. They find and interpret the all meaningful pairs of whole number co-ordinates from graphs.

Fifth graders have the opportunity to gather information themselves on Fibonacci and on the occurrence of Fibonacci numbers in nature. They divide up into groups of 2 to 4 to research.

Students investigate water usage, water available, and water demand historically in the local area. They use projections of water usage, availability and demand up to the year 2050. Students use graphs to relate as well as compare and...

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Pupils describe the characteristics and behaviors of bats. After viewing a video, they explain how bats use echolocation to navigate and how they find their young within a group. They list four misconceptions about the animal and...

Third graders review the commutative and associative property in mathematics. Using a worksheet, they work together to identify the patterns between the 32 triangles. To end the lesson, they create their own array and exchange it with...

Students practice adding and subtracting integers.  In this practice adding and subtracting integers lesson, students play a board game where they role two dice to move their token.  Students roll a sign dice and a number dice...

Students are introduced to zoning. Evaluating information and reading a land-use map is enclosed in this lesson. List new development projects that they could propose for a given area.

Fifth graders investigate the concept of finding the circumference of a circle. They demonstrate why the formula works with a hands on experiment. There is detailed instructions for carrying out the technical portions of the experiment.

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 solve quadratic equations using the quadratic formula. The teacher demonstrates solving quadratic equations and identifying the discriminant. Students model the teacher's instruction and solve sample equations on white boards....

Students practice different skills of mathematics used when working with exponents. The lesson has examples that can be used during direct instruction. They complete an exercise on a worksheet before advancing to a new standard.

Students study patterns. They construct growing patterns using pattern blocks and isosceles right triangles. They verbally describe the patterns and state the rule that describes the relationship involving the number of pattern blocks...

Students explore growth patterns by using manipulatives such as pattern blocks, investigate growth pattern of pattern, record growth in T-chart, describe how pattern is growing, and predict number of blocks needed to extend pattern.

Students practice the addition, subtraction, multiplication, and division of integers. They view a video clip on addition and subtraction of integers. Students observe a Web site that reviews multiplication and division of integers....

Students participate in a lesson that is intended for the first days of school. They are led through introductions and how the class is organized for working on a daily basis. They sign behavior contracts and other paperwork as directed...

Students investigate how to perform the operation of division with polynomials. The lesson begins with a warm up that has them factor a set of polynomials and then problems using factoring for division are introduced as guided practice.

Pupils observe the teacher writing numbers and determine the rules for scientific notation. After explanations, they perform operations on numbers in scientific nation and discuss reasons for using this method of writing numbers and...

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

Young scholars investigate the concept of subtracting fractions. They use a variety of problems in order to practice new skills. The independent practice is used to obtain an informal measurement of mastery with the use of a formal quiz...

Eighth graders demonstrate the mathematical components of a scientific problem as well as illustrate how real world problems can be solved using math. They demonstrate math skills such as rate calculation, graphing, and linear equations.
