Assess your second graders with this end of the year test. Originally meant for home school, this assessment could also be used in a larger setting. Learners complete 35 problems based on their knowledge of the second grade math...

Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.

Test your scholars' knowledge of a multitude of concepts with an assessment aligned to the California math standards. Using the exam, class members show what they know about the four operations, positive and negative numbers, statistics...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

Students investigate shapes and sizes by creating a riddle.  In this geometry lesson, students read one of two books and investigate facts about an object's size.  Students write a riddle using the facts they have read and cut...

Third graders review formulas for area and perimeter in quadrilaterals. They arrange pre-cut twine on a centimeter graph paper to create non-congruent quadrilaterals. They calculate the perimeter and area of each form.

Students study data on the nutritional value of Burger King meals in order to discover its nutritional value and also to compare the meals, using mathematical computation, to the recommended daily diet. In this data handling lesson...

In this area of polygons worksheet, students find the area of rectangles.  They find the width when given the area.  Students graph rectangles and solve word problems involving rectangles.  This three-page worksheet...

In this volume problem instructional activity, students determine the volume of various objects. They compare similar objects and determine the percent of increase and decrease of the surface area and volume. This one-page instructional...

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...

In this areas by dissection worksheet, learners find the area of given composite figures. This three-page worksheet contains examples, explanations, and 16 problems. Answers are provided on page three.

In this physics 210 worksheet, students calculate the frequency of oscillation of several word problems provided. Students find the lowest 5 modes of oscillation in each system presented.

In this perimeter and area activity, learners examine given perimeters and determine the dimensions that will give the maximum area.  This one-page activity contains four multi-step problems.

In this chemistry worksheet, students identify the name and abbreviation of the SI unit for mass, length, time, electric current, and temperature. Then they give the abbreviation for each of the units listed and describe what they are...

In this parallelogram worksheet, students examine the lengths of the sides of a quadrilateral.  They identify parallelograms.  This one-page worksheet contains 13 multiple-choice problems.  This online worksheet provides...

In this online interactive worksheet, students determine the missing length of a geometric shape and then check their answers.

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

What's similar about congruent and similar polygons? Young mathematicians first measure the side lengths and angles of given figures. They use these measurements to determine relationships between side lengths and angles of congruent and...

A fabulous set of examples and problems that introduce basic trigonometry concepts, this packet is set apart by the care it takes to integrate both radians and degrees into the material. After defining radians, the author demonstrates...

Investigate how similar and congruent figures compare. Learners understand congruent figures have congruent sides and angles, but similar figures only have congruent angles — their sides are proportional. After learning the...

Students sort and compare/contrast the lengths of various whales. They sort pictures of whales in order of smallest to largest, and given a rope marked with the lengths of the whales, they compare the actual lengths of the whales.

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Concepts are only valuable if they are applicable. An informative resource uses concepts developed in lessons 26 and 27 in a 36-part series. Scholars write equations and solve for missing side lengths for given right triangles....
