High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

High schoolers write the equation of a circle. In this geometry lesson plan, students check the solution of a coordinate pair by evaluating them. They graph the circle given the equation and radius.

Pupils circumscribe a circle about a triangle. They construct a triangle using Cabri Jr and then circumscribe it. They then use knowledge of perpendicular bisectors and circumcenters to locate the center of the circle and then...

Students discover the metric system through video clips and Internet activities. In this measurements lesson, students practice using the units of measure for the metric system and compare them to the less popular English system....

Young scholars explore slope.  In this middle school mathematics instructional activity, students analyze and interpret graphs as they investigate slope as a rate of change.  Young scholars use a motion detector to collect data...

Learners investigate surveying in this secondary mathematics lesson. They will explore a real world application of geometry and trigonometry as they create a plot plan using a geometry utility and calculate the area of the land parcel.

How do you find slope? You use points on a line of course. slope. Teach your class how to calculate and differentiate between horizontal and vertical lines. They are sure to be pros at graphing lines on a coordinate plane by the end of...

Learners perform translation and reflection. They identify the coordinate points of the new graph and create a formula for the movement. They identify the pre-image the and after image.

Students describe the differences between an estimate and a guess. They create reasonable estimates based on comparison and activities. Students explain how estimation is helpful in showing the relative size on a scale. They also...

Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.

Students select appropriate tools and technology to perform tests, collect data, and display data. They construct appropriate graphs from data and develop qualitative statements about the relationships between variables.

Students use Cartesian coordinates or degrees of latitude and longitude to locate important locations within their specific countries. They Use a grid to apply the concept of latitude and longitude, or positive and negative Cartesian...

Students review the units of the metric system, convert from the US system of units of measure to the metric system, and estimate measures before converting between the two systems of measurement.

Learners match a given velocity graph and sketch the corresponding position graph using a graphing calculator. After collecting data from their everyday life, students use specific functions on their calculators to create graphs and...

Students are able to use the Internet to conduct research. They research Mexican culture and traditions. Students compare and contrast Mexican and U.S. food and clothing. They convert United States currency to Mexican pesos. Students...

Students model projectile motion algebraically and graphically; and make predictions based on the quadratic algebraic model.

Students practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and are...

Students model and solve a real-world problem by constructing the centroid of a triangle. They explore relationships of the medians of a triangle and investigate how the centroid partitions each of the medians. Students investigate...

Students discover the value of Pi.  For this value of Pi lesson, students measure the circumference and diameter of various circles on their graphing calculator.  Students find the ratio of the circumference to the diameter and...

Fifth graders practice interpreting line graphs of the Hudson River water levels to assess the tides and tidal cycles in the estuary. They explore how weather can affect water levels and tides and observe that high tides and low tides...

Fourth graders use a map, ruler and calculato to determine the distance the pioneers traveled from Nauvoo, Ill. to the Salt Lake Valley.

Third graders review the concept of place value and number sense. With a partner, they are given four cards with numbers on them. Using the cards, they practice making new numbers and completing addition and subtraction to find the...

First graders integrate math with an upper body movement exercise. Students practice the proper push-up position. The teacher spreads paper numbers in front of the students. (Begin with the numbers 1-9.) Students must "walk" in a push-up...

Second graders read the rules of how they can balance the scale by placing beans in the square, circle, and the triangle. Next, they balance 12 beans using the scale and then try to balance it with 15 beans, and then 18 beans. They then...
