First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...

There's nothing negative about this mini-unit on integers! Engaging young mathematicians in a series of hands-on activities and collaborative learning opportunities, this resource offers an excellent way to introduce your class...

Young mathematicians identify different cases of intersecting secant lines. They then investigate the case where secant lines meet inside a circle.

Given a set of six paint mix ratios, artistic mathematicians produce an equation that relates the number of parts for blue paint to parts for yellow paint resulting new shades of green. 

Use the distributive property to solve equations. The sixth lesson in a 33-part series has scholars solve equations that need to be transformed into simpler equations first. Class members apply the distributive property to the equations...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

An ancient puzzle game meets a modern implementation. Challenge mathematicians of all ages with this mind-bending geometric puzzle game. 

How do scientists determine what questions to ask to meet their research goals? Help your class develop an inquiry mindset with a lesson based on studies in the Gorongosa National Park. Partners create their own research questions by...

The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

The lesson plan provides a richly detailed narrative and sample problems for teaching or reinforcing how to work with percentages. In particular, your audience will compute the costs per serving of food and simulate setting menu prices...

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson...

This is how long we mow the lawn together. The assessment requires the class to work with combining ratios and proportional reasoning. Pupils determine the unit rate of mowers and calculate the time required to mow a lawn if they work...

Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

In this reasoning worksheet, 3rd graders look over a table with statistics and solve the answers to 5 word problems related to the table about a class track meet.

Order in the math class! Scholars learn to evaluate expressions using the order of operations. A game has them rolling number cubes to determine numbers to use when evaluating.

Real-world multiple-step proportion problems are sometimes hard to find for your math class. Here is one designed specifically to meet that need. Learners use proportional relationships to determine price per share in the acquisition of...

As Mia and RJ discuss measurement, your class is introduced to the customary and metric systems for measuring mass, capacity, weight, and length. Temperature scales are also introduced. This resource can help set the foundation for later...

You'll C-E-R a difference in classroom achievement after using a helpful lesson. Designed for economics, civics, government, and US history classes, participants practice using the CER model to craft arguments about primary and secondary...

Given a pair of parallel lines and a triangle in between, geometers prove that the sum of the interior angles is 180 degrees. This quick quest can be used as a pop quiz or exit ticket for your geometry class.

All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create...

Help Christina figure out how many chocolate and lemon candies she has with a lesson on decomposing numbers. When presenting this context to the class, the teacher chooses the total number of candies and the number that are chocolate,...

The Common Core is intended to help all children meet high academic standards. Here is a Common Core designed lesson that is intended for learners with communication or language difficulties. The lesson is written in a narrative style...

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...
