An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

First graders place some specific types of objects (e.g., shoes, favorite food) on concrete graphs and pictographs. They listen and respond to others in a variety of contexts (e.g., pay attention to the speaker; take turns speaking in a...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Explore scientific notation in this mathematics lesson. Young mathematicians explore multiple representations of large number in scientific notation through the use of models, visual representation and expanded form. The lesson provided...

There is more than one way to represent data! Learners explore ways to represent data. They examine stacked graphs, histograms, and line plots. They conduct surveys and use stacked graphs, histograms, or line plots to chart the data they...

There is more than one way to measure an amount, as learners discover by applying multiple measurement tools in these activities. Centimeter cubes, cylinders, beakers, and measuring cups are used to find the volume of regular and...

High schoolers find the volume of pyramids and cones. In this volume of pyramids and cones lesson, learners explore the relationship between the volumes of prisms and pyramids. They investigate the relationship between pyramids and cones.

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

These four lesson plans build algebra skills for working with numbers in exponential form and for examining triangles. Be aware that in the text, scientific notation is referred to as index notation and the laws of exponents as the laws...

Here is a lesson that takes an interesting approach to analyzing data using box and whisker plots.  By using an applet that dynamically generates Venn diagrams, the class forms a strategy/algorithm for guessing the rule that fits...

Money motivates! Help young bankers understand how math plays a part in investing. Give learners math practice while instilling real-world financial literacy skills.

Students read Duke Ellington by Andrea Davis Pinkney. They complete a variety of cross-curricular activities surrounding the life of the 20th century composer. Included are reading, art, math, science, writing, social studies, and...

Seventh graders are introduced to the concept of box-and-whisker plots. A step-by-step process for creating a box-and-whisker plot is provided. The goal of the lesson plan is that students study the components of a box-and-whisker plot...

Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

Students, using manipulatives, determine how many different ways there are to arrange 3 and 4 objects. They organize and record their arrangements. Students investigate the pattern generated by 3 and 4 objects, they predict how many ways...

First graders explore counting and classification. They sort leaves, create graphs, write sentences for the data in the graphs, develop graphs for shapes, favorite animals, birthdays, and participate in a die prediction game.

Students explore the concept that to solve some problems, they may need to undo the key actions in the problem. This strategy is called working backwards asking the appropriate questions.

Students see that there are mathematical rules that can affect our use of the English language. Calculate the probability of picking any letter at random from a piece of English literature.

Young scholars explore game theory.  In this secondary mathematics lesson, students plat the game of HOG using dice and explore the optimal strategies.  Young scholars play the game three ways:  any number of dice, a fixed...

Students examine composition of dirty bomb and its possible effects on a city, and investigate simulations of such an event; students use computational and problem solving skills to assess damage and prepare report proposing solution to...

High schoolers determine an appropriate numerical representation of a problem situation, including roots and powers. They determine an appropriate number of digits to represent an outcome. Pupils are asked to determine how many years...

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Tenth graders pretend to set up an ice cream shop in a make believe town of shapes.  In this geometry lesson, 10th graders work together to put up an ice cream stand in an ideal location and solve for the minimum given the shapes.

In this statistics worksheet, students plot the possible statistical outcomes by examining the data and plotting the missing answer for the four problems.
