Long Division
Fourth graders acquire number sense and perform operations with whole numbers, simple fractions, and decimals.
Curated OER
Calculate the Answer
Students solve basic multiplication or addition facts using a calculator and product cards. They draw a card, read the sum or product, and press single digits on the calculator to display the number on the card.
Curated OER
students rotate through four workstations that reinforce the concept of symmetry
Second graders, in pairs, use arrays to explore the relationship between multiplication and division.

Cherries Are Positive, Lemons Are Negative- Part 2
Third graders, in groups, subtract integers by following Cherries are Positive, Lemons are Negative. They discover the rules for subtracting integers by using cherry heads and lemon heads.
Curated OER
Around and Around We Go
Fourth graders discover that a polygon is a closed figure formed by line segments, and that the perimeter of a polygon is the sum of the lengths of its sides. They utilize a worksheet imbedded in this plan to gain lots of practice with...
Curated OER
Pyrotechnics
Students discuss pyrotechnics and what they have noticed about their height and speed. They think about the path which fireworks follow which is a parabola. They follow multiplication patterns to determine the Zero Product Property and...
Curated OER
Kepler's Third Law
Learners use Kepler's third law to derive the velocity in a circular orbit of any radius, and identify the Earth escape velocity.
Curated OER
Integer Arithmetic
Students solve integer-based problems. They add and subtract integers as well find missing integers. They represent a scenario involving positive and negative integers and solve it.
Curated OER
Junk Yard Math
Third graders explore the process of place value and subtraction through regrouping and borrowing exercises. Several activities using manipulatives are utilized in the lesson.
Curated OER
Weather Plots
Students investigate the relationship between temperature and humidity. The graphs of weather data gathered and plotted for for an assigned period of time are analyzed and the interpretations shared with the class.
Curated OER
Motor Control AC Voltage
Students demonstrate that motors work on two different voltages. They connect a single-phase AC motor to run on different voltages.
Curated OER
Power, Work and the Waterwheel
Middle schoolers use a two-liter bottle, dowel rod and index cards to design and construct a water wheel. They then calculate the power created and measure the work done by the water wheel in Watts and Joules.
Curated OER
Jupiter's Moons
Students predict which of Jupiter's moons will be the "brightest" in infrared wavelengths. Using provided information, they rank the moos from brightes to faintest in infrared.
Curated OER
Elasticity of Gases
Students investigate gas laws and apply them in experimental conditions. Using an apparatus composed of a syringe and wooden blocks, they experimentally verify Boyle's and Charles' laws of gases.
Curated OER
Looking For Newton
The lesson has sufficient background information for the teacher to implement the lesson. Students are asked to summarize the three laws of motion. They also conduct classroom activities to role play the Laws of Newton.
Curated OER
Dissolved Oxygen
Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.
Curated OER
Combined Gas Law
Students learn the combined gas law, undersand how it incorporates all of the different relationships that they have already learned, and manipulate it to solve numberical problems.
Curated OER
Long Division
Fourth graders examine and demonstrate the steps of long division. They discuss why we use long division, and observe the teacher draw an illustration of a division problem. Students then solve a variety of long division problems,...
Curated OER
What is s and t?
Students formulate and solve various types of equations. They become familiar with different types of patterns and apply the knowledge to solving mathematical problems from analyzing them.
Curated OER
The Chromosome Connection
Learners evaluate the degree of chromosome similarity and difference between humans and apes. Students infer about the relationship between a human and ape based on similarities found.
Curated OER
Air Masses
Middle schoolers examine the physical characteristics of several types of air masses to discover how air masses can be identified and defined by their temperature and moisture content.
Curated OER
In-Line Inertia
Students practice calculating the moment of inertia when discussing a skater and the position in which it is best to spin. After class discussion, students practice calculating inertia on their own.
Curated OER
DNA Race Track
Twelfth graders simulate a DNA fragment running through a gel electrophoresis in a class activity. Students work in teams as a DNA sample with each person on the team representing a fragment that moves through the gel at a specific speed.
