Students brainstorm words that describe the weight of objects. They pick up objects and estimate the weight. Afterward, students find the exact weight and compare U.S. units of weight to metric units. In groups, students create a chart...

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Learners participate in hands-on activities using a hundreds chart and counting toes and fingers. They discover the patterns that are created when counting by ten. After a lecture/demo, students practice by using a worksheet embedded in...

Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

Fifth and sixth graders explore prime numbers. They work with a partner to build rectangular arrays using twelve tiles. Factor pairs are noted and recorded on graph paper. Pupils construct rectangular arrays with a prime number and...

Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using...

A fabulous lesson which combines mathematics with space science. Middle schoolers work in cooperative groups in order to research early astronauts and their accomplishments. They look at a variety of rocket and space shuttle designs, and...

Caesar ciphers hide secret missives. A simple interactive lets users encode and decode hidden messages. The cipher method here is the Caesar shift.

Sketch graphs with the Graph Sketcher. Scholars graph functions on a coordinate plane. An interactive makes it as easy as inputting the function and clicking a button.

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...

Go round and round to compare theoretical and experimental probabilities. Learners set the number of sectors and the number of spins for a spinner. Then, a table displays the experimental and theoretical probabilities of the spinner for...

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

Young mathematicians research and discuss real world math word problems and ways in which they apply math concepts in their everyday lives. They create a storyboard of a math word problem from which they create a slide for a multi-media...

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Math novices examine how math can help them in real-world situations. They listen to the book The Math Curse by Jon Scieszka, solve various word problems from the book, explore various math websites, write original math word problems,...

Examine how addition, subtraction, multiplication, and division relate to and are separate from each other. As they listen to the book, The Doorbell Rang, they demonstrate the math described in the story by cutting up paper cookies...

Budding mathematicians explore the concept of skip counting. They practice skip counting as they use it to determine the number of wheels that come to school at 3 different times throughout the day. They also create a data graph to show...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Students demonstrate how to tell time using an analog clock. In this time measurement lesson, students read the book Clocks and More Clocks and use analog clocks to demonstrate the time that the teacher called out.

Explore linear programming on a website game. Partners solve a real-world problem by setting up an objective function and a linear inequality. They graph their results on chart paper and also using a calculator before presenting their...

Explore the concept of measuring and recording circumference. In this physical science and measurement lesson, young learners blow up balloons, measure the circumference, and record the data on an interactive graphing website.

Access prior knowledge to practice concepts like order of operations and exponents. Your class can play this game as a daily review or as a warm-up activity when needed. They work in groups of four to complete and correct review problems.

Elementary learners explore coin mint dates. First, they listen to the book Alexander Who Used to be Rich Last Sunday by Judith Viorst. They then sort a collection of coins according to their mint date and put them in order from oldest...
