What's that buzzing in your ear? An insightful lesson about genetically modified mosquitoes! Partnered pupils explore the creation, release, and monitoring of mosquitoes designed to reduce the mosquito population. After watching a video,...

Capture the engagement of young mathematicians with this upper-elementary math lesson on measuring time and distance. Using Google Maps, students first measure and compare the distance and time it takes to travel between different...

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Speed up your scholars' understanding of ratios. Class members compare ratios related with speeds presented in different representations. They then use the unit rates to make the comparisons. 

Find the best protein-packed cereal. The short assessment task covers equivalent and comparing ratios within a context. Pupils determine the cereal with the highest ratio of protein. A rubric helps teachers with point allotments for...

Number towers use addition or multiplication to ensure each level is equal. While this is common in factoring, it is often not used with algebraic equations. Solving these six questions relies on problem solving skills and being able to...

From Pythagorean triples to the unit circle. Learners use the Pythagorean Theorem to find Pythagorean triples and then relate their work to the unit circle in a fun algebra project. Their discovery that x^2+y^2 is always equal to one on...

A deceptively simple question setup leads to a number of attack methods and a surprisingly sophisticated solution set in this open-ended problem. Young geometers of different strengths can go about defining the solutions graphically,...

How do computers store and send images? Here's an activity that explains one way a computer can compress image information. Pupils decode run-length coding to produce a black and white image. Pairs then work together to code and...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

As the Summer Olympics are approaching, incorporate Olympic-type games into the classroom. From straw javelin to cotton ball shot put, these games are sure to keep leaners engaged. The best part is that there is math involved! Pupils...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Connect linear equations, proportionality, and constant rates of change to linear functions. Young mathematicians learn how linear equations of the form y = mx + b can represent linear functions. They then explore examples of linear...

Third graders use graphing calculators to graph equations. They make visual models of algebraic expressions and they can readily see that an equation represents something.

Students collect data from measurements and weights for this experiment. In this algebra lesson, students analyze graphs they create form their data to find the expression representing the data. They label which graph provided the best...

Students study sports teams, gather data about the teams, and create a newscast about their data. In this sports analysis lesson, students research two teams and define their statistical data. Students compare the two teams, make...

Students calculate the amount of minutes they get charged for each month. In this algebra lesson, students relate linear equations to talking on the phone and the cost to do so. They create graph to plot the cost and usage of the cell...

Students practice an alternative form of data presentation. They practice sequencing data, identifying the stem-and-leaf, creating stem-and-leaf plots, and drawing inferences from the data by viewing the plots.

For this combustion worksheet, learners complete two problems using a table showing the amount of heat released when different alcohols burn. They then create two graphs plotting the energy release against the number of carbon atoms.

Students explore ways to protect the earth.  In this environmental issues and technology lesson, students investigate the water quality in their community and compare their findings to the water quality in other geographic...

Students estimate the population of a butterfly ecosystem and create a chart and graph based on information they find.

Fifth graders study the sizes of pumpkins. They measure and record the diameters of pumpkins. They create five subtraction problems and solve them. They weigh their pumpkins, record the data and select two pumpkins to make a graph of...

Students identify a question to generate appropriate data and predict results. They distinguish between a total population and a sample and use a variety of methods to collect and record data. Students create classifications and ranges...

Fifth graders analyze information about the thirteen colonies. Using the information, they can manipulate and identify a region in which the colony is located. As a class, they make generalizations about the various regions and time...
