Conquer any irrational fears you might have of irrational numbers. As class members investigate how to represent numbers geometrically, they learn about rational and irrational numbers, including approximating and ordering rational...

Create your own fraction kits by folding and labeling paper using fraction vocabulary. Learners then work in groups to use these in comparing and sequencing both whole numbers and fractions. They also create unit cubes and develop an...

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one...

Students explore number values by completing mathematical worksheets in class. In this decimals lesson, students identify the different place values a number has and the use of decimals to represent a fraction of a number. Students...

Which is colder -12 or -18? Temperature is natural real-world application of ordering rational numbers. It's also fun to talk about the lowest recorded temperature on Earth. Take the time to discuss this inquiry with your class. 

What better way to learn about fractions than with a couple pizzas? Help Jessica figure out how much of the pizza she has eaten, while teaching your class that fractions refer to a specific whole amount. This problem will be challenging...

Explore the use of non-standard units for measuring volume with elementary learners. They fill a container and count the number used using cups, spoons, and bottles, build with blocks and count the number of blocks used, and compare and...

Measure your pupil's learning in a lesson designed to explore decimals by weighing different candies on a scale and recording the weight. Small groups then compare and order the decimal weights on a number line to show their...

Students classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a system...

Who has the most? Young learners practice charting data using familiar information. They help fill out a classroom chart by recording the number of people, pets, televisions, etc. in their home. Guiding questions help them investigate...

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...

Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set students on lines that are...

Determine the level of understanding of decimal and fraction values within your classes with a resource that provides pupils with opportunities to practice with decimal and fraction concepts. 

Build a solid understanding of rational number relationships by asking class members to use various skills to order decimals, fractions, and numeric power expressions. Using the resource, they find that the fractions do not have an...

Young scholars compare the costs of two cellular phone plans and determine the best rate. They use a table and a graph of points plotted on a Cartesian plane to display their findings. Students write an equation containing variables that...

Help your kids develop strategies for counting. In this base-ten lesson, learners use matching cards, base 10 blocks, and dry erase markers and boards to examine the base 10 counting system.

Learners graph and order numbers using a number line. They also solve word problems using fractions and decimals and rewrite equations to solve problems correctly. Several example word problems are given. 

Beginning geometers use tiles and grid paper to draw and calculate perimeter and area. Rectangles of different sizes are created and then measured to build understanding. The one-inch grid sheet referenced is attached. 

Elementary or middle schoolers use ratios to discover some nearly constant relationships between measurements of parts of the human body. They find and record pairs of measurements and determine the relationship between the pairs. Pupils...

Students examine the grid in terms of a method of organization in our society as well as graphic design. In this "Making and Breaking the Grid" lesson, students design solutions to common problems and draw conclusions about patterns and...

Students compare and order integers on an umber line. In this algebra lesson, students differentiate between positive and negative numbers. They plot point in the correct order on a number line.

Students explore the concept data sets.  In this data sets lesson, students find the 5 number summaries for salaries of teachers and compare them with 5 number summaries of professional baseball players.  Students use box and...
