Axioms of Equality (Addition)
In this pre-algebra worksheet, students solve 18 equations where they must use the Axiom of Equality to add the same number to both sides of an equation. Students then evaluate 21 algebraic expressions with variables where they substitute a numeric value for each variable.
Infinite Pre-Algebra: Two-Step Equation Word Problems
In this two step equations worksheet, students solve 14 word problems in short answer format. Students write a linear equation and solve given a word problem.
Awareness of Pre-Algebra Concepts
Students demonstrate how to solve various algebraic equations. In this pre-algebra lesson plan, students work in teams and use Borenson's Hands-On Equations materials to solve algebraic equations.
Math Worksheets--Pre Algebra
In this equations worksheet, young scholars problem solve and calculate the answers to ten pre algebra equations. Students show each step of their work.
Pre-Algebra Basic Operations: Decimals
For this pre-algebra decimal worksheet, students complete a total of 28 problems performing multiplication, division, subtraction and addition of decimals and fractions.
Adding & Subtracting Fractions and Mixed Numbers
In this pre-algebra addition and subtraction of fractions and mixed numbers worksheet, learners add or subtract fractions in the first 10 problems. They write the answers in simplest terms. They add or subtract mixed numbers in the last 10 problems.
Pre-Algebra Vocabulary Crossword
For this pre-algebra worksheet, students answer questions on basic algebra vocabulary to complete a crossword puzzle. The one page interactive worksheet contains eight clues and is self checking.
Solving Problems Using Pictures
Explore problems with this sixth through eighth grade mathematics lesson. Learners investigate solving linear equations using pictures. The kinesthetic and visual use of the pictures and symbols is designed to help them develop a concrete understanding of an abstract concept.
Multiplying and Dividing Integers/Relay Race
Give your class a list of multiplication and division sentences that contain both positive and negative integers. Have them analyze them to see if they can discover the pattern with the signs. From these patterns, help them develop the rules for the operations. As a reinforcement activity, the class participates in a relay race; each individual in a row of learners completes a problem and passes it back for the next person.
Numbers Lesson 3 - Hershey Bar Fractions
Talk about delicious math! Pupils solve problems involving rational numbers and analyze real-life problems to find solutions in a pre-algebra class. They discuss the sections of a Hershey's bar in terms of fractions and decimals before taking notes and examining how to add, subtract, multiply, and divide fractions.
Solve Me - Multi-Step Equations
Students explore multi-step equations. In this pre-algebra/algebra I activity, students use the TI-nspire computer algebra system to check the steps they used to solve multi-step equations and equations with variables on both sides.
Students read and discuss two poems for meaning. In this language arts/math lesson, student count the number of letters in the poem, and then count the number of vowels and consonants. Additionally, students discuss how to turn their counts into percentages.
Students research to find a piece of artwork that contains a parabola shape. They trace the shape three times onto a coordinate plane and find the equation of each graph. The artist is also cited and each student writes a brief biography of the artist in their own words.
Real Number System Graduated Bowl Activity
Eighth graders determine which numbers are rational numbers. In this number instructional activity students answer a series of questions related to natural and whole numbers as well as integers and rational numbers. Students work cooperatively in groups.
Writing Number Sentences
Students practice writing number sentences. After reading real world problems, they describe the same situation by writing a number sentence. Students use algebra tiles, or counters, to demonstrate the use zero pairs in solving equations. They use a building mat to model adding and subtracting integers.
Similar Figure Word Problems
In this algebra worksheet, students rewrite word problems using algebraic terminology and solve problems dealing with ratios. There are 12 problems with an answer key.
Systems of Equations Word Problems
In this algebra worksheet, 11th graders solve word problems using algebraic equations. There are 8 word problems with an answer key.
Solar Flare Reconstruction
For this solar flare reconstruction worksheet, students read about the 'saturation' point of satellite detectors when solar flares are at their most intense phase of brightness. Students are given x-ray flare data and they re-plot the data to estimate the peak of intensity. They create 2 exponential functions to fit the data and estimate the peak intensity and time. Students use calculus to integrate one of the functions and calculate the total energy radiated by the flare.
Area of Circles and Probability
Students investigate the area of squares and circles. In this geometry instructional activity, students calculate the area and probability of simple events. They work on a laptop using Safari.
Proportion Word Problems
In this proportion word problem worksheet, learners read real-life problems and solve proportions. This four-page worksheet contains 18 problems. Answers are provided on the last page.
