Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

After planting a bean seed in a jar, young scientists observe the growth patterns over several days. As the bean becomes a sprout, and the sprout becomes a plant, partners measure and plot the data. They notice patterns, practice...

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Save those precious minutes and hours spent planning math lessons with this mini-unit on telling time. Offering a series of engaging hands-on and collaborative learning activities, these three lessons teach children how to read...

Reinforce math concepts with a five question, mixed practice learning exercise. Questions presented as word problems require scholars to show what they know about multiplication, division, money, and converting inches to feet.  

A fun activity is presented in this math worksheet. Youngsters mark off seven of their footlengths, then perform other measurements of their bodies to see if there are any correllations. Students discover that, for many of them, their...

Young mathematicians collect data on the arm spans of classmates. Then they sort the data by measures of center, spread, and standard deviation. Finally, they compare groups, such as boys and girls, to interpret any differences. 

Applying this metric worksheet, mathematicians will provide standard metric units of measurement, identify the largest and best way to measure items using the metric system, and convert units using King Henry.

Curves ahead! Develop a numerical measurement of curvy-ness. The class is challenged to come up with a definition of curvy that can be applied to curves. The class members use their defined measurement to describe a curve.

It's always nice to hear from friends. Your budding mathematicians read letters from pen pals and convert customary measurements into metric units and vice versa. They also write letters to an imaginary pen pal using metric units.

Facilitate an understanding of equality using a modeling task. After watching different-sized cups being stacked, learners use their math skills to determine when the height of each cup tower will be the same. Meant as an introduction to...

Time flies when you're teaching math! Okay, maybe not for everyone, but this lesson will have your young mathematicians calculating elapsed time before you know it.

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

Reinforce concepts and encourage learner engagement with a collection of math games, science experiments, and cross curricular activities. In one fun resource, learners sort objects, keep a diary of everyday fractions, play a game using...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Explore relationships between perimeter and area. Learners compare the measurement units of gligs and crocs. They use a given perimeter and area as well as specific measurement relationships to determine the scale of gligs to crocs.

Have you ever finished a piece of cake and wished you had more? Solve this common dilemma with math! A straightforward worksheet prompts middle schoolers to use the given dimensions of a heart-shaped cake when planning to bake two larger...

Use geometry to improve your pool game! Learners analyze the front half of a pool shot to determine its resulting path. By measuring the angle of incidence, they are able to predict the path of the ball. 

Measure angles in more than one way. The interactive introduces the concept of measuring angles from 0 to 360 degrees. Scholars explore the relationships between the angle and reference angles along with coterminal angles.

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Connect division with multiplication through the use of models. Groups solve problems involving the division of a whole number by a fraction using models. The groups share their methods along with the corresponding division and...
