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.

Ours is to wonder why, not just to invert and multiply. The seventh installment of a 21-part module uses fraction models to help pupils understand why the invert-and-multiply strategy for dividing fractions works. They then work on some...

Scholars apply the concepts of box plots and dot plots to summarize and describe data distributions. They use the data displays to compare sets of data and determine numerical summaries. 

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This lesson can be extended for algebra,...

There are a number of activities here where learners collect and record data, as well as, activities where the likelihood of an event happening is calculated given the experimental probability. Young statisticians organize information...

Learners explore characteristics of mass. In this scientific inquiry about mass lesson, students drop rocks of different weights from various heights and record the depth of the "crater" created.  Learners record their findings on a...

Students make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

Students compare and contrast the two measurement scales of Fahrenheit and Celsius. They calculate the temperature using both measurements. Students demonstrate their comprehension of these systems by creating a dual-system thermometer...

Students predict, plan, and gather information for a metric measuring challenge. They cooperatively measure the perimeter of their school building using appropriate tools according to a plan they devise together. Students create...

Sixth graders measure distances on a map using string and a ruler. They complete mathematical word problems about measurement.

Upper elementary and middle schoolers describe the various features of unit cubes, such as edges, corners, and faces. They also discuss how to represent measurements of a cube using exponents before engaging in various thinking and...

Upper grade and middle schoolers discuss their favorite TV programs, music, books, etc. Following a lesson on measures of central tendency, learners discuss random sampling. They conduct a survey and use charts and frequency tables to...

Students research flag designs and their geometric configurations. They design their own fraction flag and utilize the concepts of measurement, geometry and fractions to their designs. Each student attaches a craft stick or short dowel...

Pupils measure their school photographs and cut mounting paper with a wide border for a frame. They design and create a unique picture frame suitable for a gift or family keepsake.

Learners estimate relative size and scale of humans, animals, and objects. They verify their estimations through research and measurement and then draw themselves in proportion to other creatures, both larger and smaller, in a selected...

Students use estimation and measurement skills to make predictions and solve problems involving length.

Students study metric measurements in the sport of track. In this metric measurement lesson, students watch a video clip to help them understand the different starting points for a track race. Students discuss the size of a meter and the...

Middle schoolers discover how to measure in one and two dimensional space and calculate how much space any object of a given dimension occupies. After a discussion about dimensions, students work with Zome System Creator Kits to build...

Young scholars measure their bodies. In this math lesson, students record their height and weight. Young scholars measure themselves in six months and observe any changes.

Introduce your math class to the perimeter of a circle. Teach them that pi describes the relationship between the circumference and the diameter. As a hands-on investigation, pairs or small groups use string to compare these two values...

Students analyze the relationship between radius and diameter.  Students read Sir Cumference and the First Round Table then take measurements of circular items from around the room.  Students compute the radius, diameter...
