Don't assume your pupils understand assumptions. A teacher resource provides valuable information on inferences, assumptions, and conditions, and how scholars tend to overlook these aspects. It focuses on regression analysis, statistical...

Students examine stereotypes and how to identify their own assumptions.  In this bias and assumption lesson plan students read a story and complete a worksheet. 

What would future archeologists learn from your scholars' personal belongings? Have them bring in a box of "primary sources" from their home. Discuss the difference between observations and inference, using some of your own items to...

How many hot dogs does Fenway Park go through in a year? Learners estimate answers to this question and more as they work through the task. Problems require participants to make assumptions and use those assumptions to make estimations.

Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

How many cars would be involved in a traffic jam 12 miles long? A slightly ambiguous writing prompt gives learners the opportunity to practice making reasonable assumptions to tackle a real-life problem. Few details are given, so they...

Students discuss the importance of not making assumptions when only little information is known. With a partner, they complete a worksheet in which they only look at them to figure out what they like, etc. Next, they ask them the...

Did the Confederate Army really consist of southern volunteers? Using primary sources, historians examine the story behind the "Twenty Negro Law" and realities of conscription during the Civil War. A letter and a lithograph (included as...

Your learners will make good use of the Socratic method in a collaborative task that begins with an assumed solution and ends with deeper understanding of the idea of determining two triangles congruent.

Middle schoolers identify what and how to complete an Archaeological excavation is conducted. They identify the transition from one layer to the next more easily if the colors of the layers are different. When creating a dig, the...

Young scholars assume the role of a crime scene detective and examine the lives of various immigrant groups. In this immigration instructional activity, students examine evidence, websites, and pull from existing knowledge to determine...

Students investigate how Hardy-Weinberg Equilibrium is established and what assumptions and conditions are necessary to reach Equilibrium. They model alleles using materials such as index cards, M & M's and goldfish.

Students study how Hardy-Weinberg Equilibrium was established and what assumptions and conditions are necessary to reach Equilibrium. They record class data on their charts. Frequencies are calculated.

Fourth graders explore, examine and study ceramics, a medium of historical importance to China. They review the advanced technology of the early Chinese civilization and are introduced to the scientific method of inquiry and make...

Learners explore their perspectives of different occupations, discover what life skills will be valuable to them in whatever career path they choose, and discuss important terms related to the work environment. 

Students read a primary source document about the rules of civility and behavior in the presence of company. Using the text, they make assumptions about how life was like in the colonies. They compare and contrast the culture of the...

High schoolers explore the Method of Solution. They identify the components of the Method of Solution. Students develop the method of solution for a project that includes how the computer will be used, the mathematical equations needed...

Young scholars are guided through the Scientific Method to perform observations about the pupa stage of the monarch butterfly. The results of an experiment are used to make assumptions about growth and development.

Why did the Articles of Confederation fail? Your historians will find out firsthand through this simulation activity, during which they will use money (consider using extra credit) to demonstrate the inherent flaws. It's simple: each...

What does it mean for something to grow exponentially, and how does that compare to linear growth? This activity tries to help learners gain an understanding of these concepts while modeling real-world problems. Linear and exponential...

Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....

Show your classes how different means can represent the same data. Individuals collect household size data and calculate the mean. Pupils learn how handling of the data influences the value of the mean. 

Keep your classes climbing in the right direction. Young mathematicians collect data from a video presentation. Using their data, they build an arithmetic sequence and use it to make predictions.

Assess your young mathematicians' knowledge and understanding of the properties of exponents. The questions in the seventh lesson of 15 incorporate the properties learned in the first six modules of this series. Individuals use and apply...
