Students identify the different place values. In this algebra lesson, students represent decimal place values with manipulatives. They identify the correct place value using commas and mathematical reasoning.

Creative problem solving is fun and helps kids conceptualize content. They use grid paper, manilla paper, and markers to cut, draw, and show given double-digit numbers as many ways as they can.

Students investigate unit conversion.  In this unit conversion lesson, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The tables...

Introduce young mathematicians to concepts of financial literacy with this open-ended word problem. With seven dollars to spend during field day and given a list of available items and their prices, children must determine how they want...

Sometimes simple is just better. A set of activities teaches young mathematicians about using plausible estimation to solve problems. They break problems down to simpler problems, use rounding and estimation strategies, and consider...

Eighth graders investigate properties of circles.  For this eight grade mathematics lesson, 8th graders apply proportional reasoning to data gathered with “Google Earth” to calculate equatorial and polar circumference of the...

Young mathematicians join the ancient order of the Pythagoreans by completing an assessment task that asks them to find the area of tilted squares on dot paper. They then look at patterns in the squares to develop the...

As part of a study of geometric patterns, scholars complete an assessment task determining the number of tiles needed to cover a tabletop. They then evaluate provided sample responses to see different ways to solve the same...

Learners analyze the costs and benefits that are involved with owning a business. They create their own decision making grid and identify their trade-offs. They also identify the opportunity costs involved in owning their own business.

Students examine an ISS EarthKAM image of farm land in Texas and New Mexico. They select sample region of image and count the number of fields in that region. They estimate how many fields are in the entire region.

Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

Factor polynomials using electronic manipulatives. Your class will create a spreadsheet in excel and use it to multiply and perform basic operations and solve problems correctly. They create a visual to go along with each multiplication...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

It's the stairway to learning! Scholars research all aspects of building a staircase. Using information from building codes, they write and graph a system of inequalities to analyze the constraints. The completed project is a scale model...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Third graders roll a die seven times, each time determining whether to add that number of tens or that number of ones to try to make a sum as close to 100 as possible without going over.

Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

Students investigate ratios of various objects.  In this ratios of various objects instructional activity, students draw pictures on graph paper and then dilate or shrink the image.  Students determine the ratio of their...

Students comprehend what has been explored in the previous earthquake engineering design lessons, by putting their designs to the test. They are given pairs a piece of paper, and an empty plastic bottle or can. Students stand the...

Second graders collect data by spinning two spinners and creating sums, organize the data, and make conclusions from the data. Each students makes a spinner. They spin and record the number of the section each time. Students work in...

Sixth graders are introduced to the concepts of area and volume. In groups, they work together to build models of square centimeters in which they are given no instructions. To end the lesson, they record the dimensions of each model...
