Fight against the current. Pupils explore the resulting path when they are crossing a river while being pushed downstream by the current. Using vector notation, learners express the speed and direction of a ferry. They finish by...

Learning to read data tables is an important skill. Use this resource for your third, fourth, or fifth graders. Learners will will study tables of fish collection data to draw conclusions. The data is based on fish environments in the...

Students explore mass and volume. In this mass and volume instructional activity, students pretend to be on a hike and have lost their way. Students must cross a river get back on track. Students must use mass, volume, surface area,...

High school students examine their own water-based environments, within the Mystic Watershed. As the learners engage in inquiry-based, hands-on projects, critical thinking skills and problem-solving, the project will lead them to cross...

Fifth graders practice interpreting line graphs of the Hudson River water levels to assess the tides and tidal cycles in the estuary. They explore how weather can affect water levels and tides and observe that high tides and low tides...

Using the answers to the challenge questions, class members work through simplifying a complex logarithmic expression that requires changing bases. Pupils drag values to fill in the steps to arrive at a numerical equivalent expression.

Students use math to plan a trip by houseboat down the Mississippi River. They research and obtain information on the Mississippi River and its surroundings and use multiple graphs to represent their data.

Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks...

Write a math story for a series of problems using given variables. The class writes stories, showing understanding of strategies in compound sentences. They then solve the equations.

Ensure your class has a solid understanding of positive and negative integers before moving on. The 14th installment of a 21-part series is a mid-module assessment. Scholars solve problems on positive and negative integers, on...

The behavior of a rational function near a vertical asymptote is the focus around this trip up a river. Specifically, numerical and graphical understanding is studied. The canoe context pushes the variables as numbers, rather than as...

Young mathematicians are introduced to fractions in a unit that helps them to understand parts of a whole.

Challenge classes to think deeply and apply their understanding of polynomials. The assessment prompts learners to use polynomial functions to model different situations and use them to make predictions and conclusions.

Is river pollution affecting the number of visitors to Riverside Center, and is the factory built upstream the cause of the pollution? Let your class be the judge, literally, as they weigh the statistical evidence offered by the factory...

Students define the different methods used for optimizing a particular element of a problem. In this optimization problem lesson, students optimize appropriate details of a problem using data collection, algebra, technology, and/or...

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Third graders read the article "Blue Claw," discuss crab migration, and look at a map of the Hudson River. They complete a worksheet where they must use subtraction to determine the distance migrating crabs travel.Web links, article, and...

Middle schoolers are introduced to the concept of scatter plots after reviewing the various types of graphs. In groups, they analyze the type of information one can receive from a scatter plot and identify the relationship between the x...

While this lesson focuses on a study of the Hudson River, it could be used as a template for a discussion of map skills, converting measurements, and plotting a route. The lesson includes vocabulary and other resources to make it a...

First graders identify and demonstrate how symbols and models are used to represent features of the environment. They identify the directions on a map as east, west, north, and south. Finally, 1st graders play a direction game, move to...

Students explore change represented in graphs comparing distance and time. They exchange and share their graphs. Students interpret and create distance versus time line-graphs, and write stories based on these graphs. They interpret a...

How can kids use math to learn about marine life? Combine math skills with science lessons in a resource featuring activities about life in the sea. Kids graph and calculate data, solve complex word problems, measure geometric shapes,...

Students use tables of fish collection data to draw conclusions about where fish live in the Hudson Estuary. Given available data they interpret organized observations and measurements and recognize simple patterns, sequences, and...

For this multistep problem worksheet, students use the problem solving method of understand, plan, solve, and look back to help them solve the two multistep problems.
