You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Can you use X-rays to measure bone mineral density? This is the essential question that learners must answer in the first installment of a seven-part series. They brainstorm ideas about necessary background information and what they...

Students investigate the concepts related to the study of polygons. They specifically look at how angles is related. The lesson plan includes specific examples and dialogue to be used by the teacher during direct instruction and...

Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.

Does the volume formula work even if the measurements are not whole numbers? Class members work simple problems to find that the formula (area of the base) × (height) works for all prisms, independent of measurements and shape.

Geometry could be called the study of figures. An overview of the figures found in a typical geometry course contains a study of different triangles, quadrilaterals, and regular polygons. 

Hold measurements to a different metric. Class members convert the measurements of a dog's tumor to explain the size to its owner. Using cards, learners match metric measurements with their English equivalents. They then read articles to...

Which number is bigger? Using a variety of activity sheets, this unit starts with the basics of inequalities and progresses through solving compound linear inequalities. Problems cover the range of inequalities including inequality word...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to...

Create a strong understanding of the relationships formed when parallel lines intersect a transversal. Discuss each type of angle pair and their relationship to each other. 

Whiskers are not just for cats! Pupils create box-and-whisker plots from given data sets. They analyze the data using the graphs as their guide.

Using patty paper, classes determine that only one triangle is possible when given two specific angle measures and a side length. As the 10th instructional activity in the series of 29, young math scholars add these criteria to those...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Parallel lines seem so right for each other. It's too bad they'll never, ever meet. Learners use tracing paper to discover relationships among angles formed by two parallel lines cut by a transversal. They apply this information to find...

Students cut yarn into several different lengths and fold paper in half, using skills for measuring and fractions. Then they use unconventional items (yarn) as tools to create mirror-image art and experience first-hand the math idea of...

Construct your young mathematicians' understanding by exploring the properties and dimensions of a parallelogram through constructions. The seventh instructional activity in this 29-part series begins with individuals creating...

What do you get when you slice a prism? Pupils discover that the answer depends on how the prism is sliced. The second half of the 29-part module focuses on three-dimensional objects. Learners use their two-dimensional vocabulary and...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Students follow directions to complete a multi-step process that results in an attractive holiday decoration. In this Christmas art activity lesson, students employ simple measuring and weaving techniques and experiment with the negative...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

Students employ simple measuring and weaving techniques. Then they experiment with the negative and positive space of a cutout. Students also follow directions to complete a multi-step process that results in an attractive holiday...

Eighth graders measure in feet and inches and convert to explore the relationship between the converted measurements. In this measurement lesson, 8th graders use the whisker and box plot to represent the measurement of a cat. ...

Demonstrate how to read analog and digital clocks to the hour in this time measurement lesson. Read the book What Time is it Mr. Crocodile? and use Mr. Crocodile's schedule to practice telling time. They work in cooperative groups to...

Students convert degrees between two different units. In this algebra instructional activity, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.
