Students complete the following problem by using logic: Three couples, the Smiths, the Jones and the Browns wanted to go to the Brown's yacht that was moored a little way out in the lake. There was a dinghy to take them to the yacht but...

Third graders in a 3rd grade math class make connections from prior instruction and mastery to solve problems in new learning situations. Using logical thinking and prior knowledge to solve current math problems is the focus of this...

Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

In this secondary mathematics worksheet, learners solve problems that involve patterns, arithmetic and geometric sequences, geometric logic and reasoning, and changing bases.  The three page worksheet contains fourteen...

Young scholars explore the nature of mathematical proofs and mathematical inquiry. They complete the activity "Using the Pythagorean Theorem". They read selected articles and participate in class discussions.

Fourth graders study changes in animal population. In this graphing instructional activity, 4th graders create graphs from information read to them about hares and lynx populations. They will describe patterns of change in the graphs and...

In this Algebra II worksheet, 11th graders explore two examples of arguments that can be formalized with mathematical induction.  The one page worksheet contains two problems with explanation. 

High schoolers devise a strategy to solve problems that is done in a systematic and mathematical fashion. The finding of the unknown value is the focus of the lesson. To solve linear equations proficiently is the skill of the lesson.

High schoolers make sensible estimates and check for reasonable results. They also solve problems with positive and negative integers using practical activities or models as needed.

Third graders focus on developing a systematic approach to problem solving while working on a problem that requires them to determine possible outcomes. They use a pegboard as a manipulative in this problem.

Students examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. They practice science and math in real world applications. They write reports detailing their scientific...

Students, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of the...

Looking for analogies? Here are 501.

Students complete an interdisciplinary unit chronicling the life cycle and movement patterns of the butterfly. Through language arts, mathematics, and science activities, students identify various types of butterflies and document the...

Students explore how archaeologists make inferences from artifacts to explore what life was like in the past. In this archaeology lesson, students work in groups and make inferences about an imaginary household based on modern day...

Students download information from a NASA website into a database. They transfer it to a spreadsheet by completing the information and analyze the information. They determine temperature averages, mode, and graph the results. They write...

Students decide how many rides it takes at a county fair to benefit from bargain tickets.

Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create quadrilaterals

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Here is a problem-solving lesson that has learners take the role of a packaging expert to design an inexpensive means of packaging a potato chip. It could benefit from having more specific detail about the lesson itself, but it does make...

Young scholars explore temperature and use Celcius thermometers to measure and graph the temperature in the classroom daily. They estimate what they think the temperature might be and then find the actual temperature in the room.

Students view a demonstration that simulates cloud formation. They read a poem about clouds, participate in a class demonstration using warm water and ice and write a paragraph summarizing their observations.

Middle schoolers work as travel agents to plan an around-the-world trip to all of Hemingway's favorite world locations. They plan an itinerary which includes facets of the trip and record the information in their journals.
