An excellent activity that effectively pulls together the concepts of area, fractions, and equivalent fractions! Using 3x2 rectangular arrays, 3rd graders are introduced to the concept of area in terms of square units. Building on this...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

In this beginning division worksheet, students draw circles around groups shown, dividing sets of objects. A reference web site is given for additional activities.

In this shape worksheet, students color shapes that belong with a group, and write an X on shapes that do not. A variety of shapes are used, 6 sets total.

In this math activity activity, students read groups of five to nine numbers and find their mean, median, mode, and range. Students solve 24 problems. 

Animals move in interesting ways! Get your young learners to examine various types of animal movement in this group graphing activity. Although directions are not explicit, it seems students are assigned an animal and categorize the...

Practice finding the averages of different groups of numbers. Third graders review an example at the top of the page, then find the averages of fourteen groups of numbers (with eight numbers in each group). The instructional activity is...

A three-part assessment challenges scholars to write opinion essays covering the topic of the student council. After reading three passages, writers complete a chart, work with peers to complete a mini-research project, answer...

Visual models are a great tool for demonstrating the concept of equivalent fractions. Given two pictures, young mathematicians first identify each fraction and then write an explanation for why they are equivalent. Use as a guided...

What does an MRI machine have to do with a slinky? This activity challenges learners to run a current through a slinky and use a magnetic field sensor to measure the magnetic field. Groups then change the length of the slinky to see...

Upper elementary and middle school pupils fill out a chart creating six equivalent fractions and then compare them to six different objects and/or shapes. They group together 16 various terms related to ratios and proportions. Pupils...

Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...

Add up areas of squares to discover the pythagorean relationship. Small groups create right triangles with squares along each side. They calculate the areas of each square and notice the relationship. Groups construct other types of...

In this points, lines, planes, and space worksheet, students solve word problems dealing with points, lines, planes, and space. Students complete 20 individual problems and 20 group problems.

How many is this? Practice number value recognition between 0 and 20 using this interactive activity idea. It's all here for your easy use: cut and laminate the twenty-one individual cards, each labeled numerically 0-20. Also cut out the...

Goldilocks and the Three Numbers? The pre-activity task involves finding digits to complete decimals or fractions that satisfy given constraints, such as finding a fractions that is in between two others. The main task involves a similar...

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation. They perform...

Every time a bell rings ... there is lightning in the area. The activity provides directions to build a model of a lightning detection system. Similar to a system designed by Benjamin Franklin, the system uses static...

So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings. 

In this petroleum products worksheet, learners are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that represent...

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Can survival rates on the Titanic be explained by the "women and children first" policy or did rescue procedures favor the wealthy? Use actual historical data to explore conditional probability and independent events with your class....

Dividing with fractions can be a confusing task to some, but the activity illustrates how to make groups out of the problem and look at it visually. Use this problem with the lesson in the Additional Materials section to practice this...

To find x, you have to get it by itself, correct? Individuals solve a linear word problem and share their solutions with others that solved the problem in a similar fashion. They then complete a self-assessment on how they feel about...
