Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.

First graders complete activities with the story One Monday Morning in the Macmillan/McGraw Hill Textbook. In this data lesson plan, 1st graders read the story and gather data to create a picture graph. They read the graph and...

First graders conduct a poll about how people like their eggs. In this graphing lesson, 1st graders collect data about how they like their eggs. Students use a picture of themselves to place under the type of egg they like. Students then...

Fourth graders practice finding the perimeter of shapes.  In this measurement lesson, 4th graders review the meaning of perimeter and work in groups to draw polygons with differing perimeters.  Students share their polygons...

Sixth graders work in teams to design the perfect bedroom. The teams must create a room that is functional, original, and stays within a budget of $650.

In this length and width learning exercise, 2nd graders draw 6 specific items or objects that are the following measurements: 6 feet tall, 3 inches long, 9 inches long, 1 inch wide, 25 feet long and 4 feet long.

Students explore ocean vessels that drill the ocean floor. For this ocean drilling lesson, students watch videos about drilling the ocean floor and discuss. Students get into groups, go outside and use string to mark off the...

Students view a quicktime video of basketball players going from Atlanta to Springfield, Mass. In this scaling lesson, students use a map to calculate the distance of the trip and the length of travel time. Students apply ratio and...

Young scholars generate plans for a fictitious road trip.  In this time management lesson, students investigate the most effective way to travel the country arriving at specific cities.  Young scholars create their plans based...

Assist your class with each angle of geometry as they use exterior angles to form linear pairs with adjacent interior angles. They cover multiple vocabulary terms and work practice problems, complete with justifications, before...

Looking to challenge your students that have mastered basic triangle congruence proofs? A collection of proofs employ previously learned definitions, theorems, and properties. Pupils draw on their past experiences with proofs to...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar...

How do you solve an equation like trigonometry? Learners apply their understanding of trigonometric ratios to find unknown angles in right triangles. They learn the meaning of arcsine, arccosine, and arctangent. Problems include...

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

Use a unit approach in developing a fraction division strategy. The teacher leads a discussion on division containing units, resulting in a connection between the units and like denominators. Pupils develop a rule in dividing fractions...

Investigate bubbles through the use of scientific inquiry. Pupils blow bubbles using several methods and measure the resulting bubble print. Measurements are recorded on a data table and transferred to a bar graph. Results are discussed...

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

How many different interpretations of the mean are there? Scholars place numbers on a number line and determine the mean. They interpret the mean as the average value and as the balance point.

Can they put it all together? Ninth graders apply what they know about proofs and triangle congruence to complete these proofs. These proofs go beyond the basic triangle congruence proofs and use various properties, theorems, and...

So the mean is not always the best center? By working through this exploratory activity, the class comes to realize that depending upon the shape of a distribution, different centers should be chosen. Learners continue to explore...

Provide your emerging mathematicians with the tools to learn as they incorporate auxiliary lines to solve unknown angle proofs in this continuing segment. They decipher information from a diagram to uncover the missing pieces and...

What does it take to show two triangles are similar? The 11th segment in a series of 16 introduces the AA Criterion for Similarity. A discussion provides an informal proof of the theorem. Exercises and problems require scholars to apply...

Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...

As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal.
