Mathematicians separate numbers into subsets. In this algebra lesson plan, they define and differentiate numbers according to real numbers and integers, fractions, and rational numbers.
Who doesn't like to eat? Use food to explore the concept of fractions and how to multiply and divide fractions. In small groups they plan a sugar potluck that involves converting a recipe to produce enough dessert treats to feed the entire class. Math learners calculate the amount of ingredients for the entire project and for each individual recipe, make their recipe, and share it with the class.
For this fractions, decimals, and percents lessons, students explore various methods of representing fractions. They demonstrate situations that represent rational numbers. Students create a foldable exploring fractions, decimals and percents. They use an area model, meter sticks, and base-ten blocks. Students play a game of fraction, decimal, percent bingo.
In this rational numbers worksheet, learners identify rational and irrational numbers.  They examine square roots and fractions.  This one-page worksheet contains 5 multiple-choice problems.
Students investigate rational numbers through data analysis and statistics. In this algebra instructional activity, students represent, rename, compare and order rational numbers. They collect and represent data correctly on a graph.
Students investigate ratios and percents and convert between the two. In this algebra lesson, students write ratios using fractions. They write percents as fractions and decimals and they apply the concepts of the Fibonacci rectangle to solve problems.
Estimate the value of an nth, or square root. Your class can compare their estimates and place them in proper sequence on a number line. An extra activity could be to justify reasoning and discuss strategies used.
Fourth graders explore nine levels of Pascal's Triangle. They color multiples of specified numbers.
Students explore the TI-92.  In this secondary mathematics instructional activity, students examine the applications and functions of the TI-92.  Students investigate symbolic manipulation, 2D and 3D graphing, the interactive geometry module and the programming and text editor. 
In this number sets worksheet, students identify whole numbers, integers, and rational numbers.  They give examples and counterexamples of each.  This one-page worksheet contains 12 problems.
Students investigate the area of a circles. In this algebra lesson, students investigate the quadratic equation representing a circle, find the radius and area of a circle and define the area and a quadratic function is related.
In this radical expressions worksheet, 11th graders solve and complete 55 various types of problems. First, they find the function value in each expression. Then, students simplify, assuming that variables represent real numbers. In addition, they find the domain and rewrite without the fractional exponents.
Eighth graders review their understanding about numbers and number systems through playing the Number Game. They create a list of numbers and based upon the characteristics and properties of the numbers they will earn points.
Students investigate rational expressions by playing a game. In this algebra lesson, students solve rational expression using addition, subtraction, multiplication and division. They apply the correct order of operation to get the answer.
In this algebra worksheet, students solve rational numbers using addition, subtraction and multiplication. They identify the rules of solving rational and irrational numbers. There are 50 questions on 6 pages.
First graders define and identify integers, rational, irrational, real, and complex numbers. They place number cards in ascending and descending order.
Fourth and fifth graders practice basic operations with fractions. For this fractions lesson, pupils add, subtract, multiply and divide fractions, first with teacher guidance and then with a computer game called "Fraction Four."
Students explore the concept of fractions. In this fractions lesson, students perform basic operations such as addition and subtraction with fractions. Students play a game on the computer called 'Fraction Four' that gives students practice computing with fractions.
In this square roots and real numbers worksheet, 9th graders solve and complete 12 different problems that include types of numbers. First, they find each square root, rounding to the nearest hundredth. Then, students evaluate each expression and then, name the set or sets of numbers which each real number belongs.
In this rational numbers practice activity, students review their math skills as they identify the opposite of several rational numbers and plot fractions, mixed numbers, decimals, and integers in the provided space.
