Ratios and Percents
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.
Number Lines: Roots
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.
Practicing Multiples using Pascal's Triangle
Fourth graders explore nine levels of Pascal's Triangle. They color multiples of specified numbers.
Introduction the TI-92
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.
Homework #4: Number Sets
For 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.
Quadratics and Exponential Functions
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.
Estimating with Rational Numbers
Young scholars explore the concept of rounding. In this rounding lesson, students round fractions and mixed numbers. Young scholars estimate the sums, differences, products, and quotients of rounded fractions and mixed numbers.
Young scholars investigate rational numbers in this algebra activity. They graph systems of equations and use technology to find the point of intersection. They need a TI for this assignment.
Integers: A Real World Rational Numbers Application
Given centigrade temperatures for pairs of cities, math-minded meteorologists determine which is either warmer or colder. The worksheet is embedded in a website from which you can access an answer key or even change the cities and temperatures with a simple click! There is also a link to another similar worksheet in which problems are written out in words.
Algebra Practice: Equations With Rational Numbers
Young mathematicians solve 12 equations, determine operations performed and solve 2 test prep questions. Houghton Mifflin text is referenced.
Number Subsets: Winning the Number Game
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.
Discovering Math Computations
Young scholars investigate rational expressions by playing a game. For this algebra lesson, students solve rational expression using addition, subtraction, multiplication and division. They apply the correct order of operation to get the answer.
Algebra Worksheet: Number systems
This worksheet was originally created for a college level algebra class. It does contain some interesting questions about number and quantity that are important for algebra learners to understand. Natural numbers, integers, rational, irrationals, exponents, and absolute value are all considered.
The Irrational Numbers
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.
Order in the Classroom
First graders define and identify integers, rational, irrational, real, and complex numbers. They place number cards in ascending and descending order.
Students explore the concept of fractions. In this fractions instructional activity, 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.
Square Roots and Real Numbers
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 learning exercise, 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.
In this rational numbers worksheet, 6th graders rewrite rational numbers in the form of a/b. There are eighteen rational numbers to rewrite and two test prep questions.
