Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

How has the level of carbon dioxide changed over recent years, and what is contributing it? Groups work together to research and present their findings in a creative way. Also built into the lesson is a visit to a sustainable house, but...

A resource that makes for excellent group work as students explore the area and perimeter of different complex designs made up of squares and circles. The commentary gives a clear definition of perimeter, but suggests that group members...

Students explore their counting skills. In this counting lesson, students group objects in sets of 10 to practice counting them. Students also practice graphing the sets of objects they count.  This lesson incorporates the...

Youngsters improve their measuring and counting skills using sunflowers. They view pictures painted by Van Gogh. Everyone works in groups to measure sunflowers and record their findings, and they all use sunflower seeds to create...

Here's a way to create math fact flash cards! Learners create their own cards and sort them into matching categories. Learners start with addition and work their way up to harder math such as multiplication, and are asked to notice...

A second attack at figuring out the number of leaves on a tree, this activity makes both an excellent follow-up to version 1 and a stand-alone activity. Learners practice setting parameters and deciding acceptable estimate precision, and...

Small groups work through two guided activities to derive the distance and midpoint formulas for the coordinate plane. The activities begin with concrete examples and move to abstract.

Pupils work in pairs to investigate what it takes to prove that two triangles are similar. They work through various shortcuts to find which are enough to show a similarity relationship between the triangles. Small groups work with the...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

Capture the engagement of young mathematicians with this hands-on sorting activity. Given a bag of objects, young scholars work independently sorting the items based on their physical attributes, counting to determine the size of each...

Public transportation is an important aspect of any growing city. Collaborative groups work to redesign a system for a city in need of restructuring. Young scholars design a route, create a timetable, and incorporate a quality control...

Upper elementary and middle school scholars study the economic factors that caused so many Arkansans to migrate to different parts of the country looking for work. Use this history lesson plan to help your charges gain a better...

Learners solve vacation equations using tape in a lesson plan that utilizes tape diagrams to aid in understanding the algebraic steps involved in solving two-step linear equations. Groups work together to solve seven scenarios involving...

If you use a fabulous lesson plan, then your pupils can become fabulous at solving equations. The 24th installment of 25 incorporates the use of if-then statements to illustrate the properties of equality used in solving two-step linear...

Fifth graders rotate through six math stations to solve a variety of story problems involving multiplication and division. They observe a demonstration of how to do multiplication and division using grouping, then solve the story...

Students are able to identify the units associated with linear work. They are able to calculate the work done on an object. Students discover how the force exerted on an object and the distance the object moves determines the work done...

Learners will look at repeating addition examples and view how they can be written as multiplication. They use manipulatives to complete a repeating addition lesson plan and show it on graph paper. They also chart what they have found...

Connect division with multiplication through the use of models. Groups solve problems involving the division of a whole number by a fraction using models. The groups share their methods along with the corresponding division and...

Working in small groups and in pairs, classmates build an understanding of what types of relationships can be used to model individual scatter plots. The nonlinear scatter plots in this lesson on relationships between two numerical...

Pupils work several real-world problems that use percents in the 11th portion of a 20-part series. The problems contain percents involved with taxes, commissions, discounts, tips, fees, and interest. Scholars use the equations formed for...

What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Collaborative groups utilize their knowledge of parent functions and transformations to determine the equations associated with graphs. The graph is then related to the scenario it represents. 

Changing ratios make for interesting problems. Pupils solve problems that involve ratios between two quantities that change. Groups use tape diagrams to represent and solve classroom exercises and share their solutions.
