Seventh graders practice adding and subtracting with common fractions including lowest common denominator and least common multiple. They incorporate fraction kits and calculators to assist them with their equations as well as a multitude of strategies to try out within this lesson.
Lower graders explore recursive patterns. They use a calculator to recognize, generate, and explore patterns during arithmetic explorations. The unit provides several assignments of an exploratory nature designed to assist in developing mathematical thinking and reasoning.
In this common factors and GCF worksheet, students list the factors of the specified numbers and then find the greatest common factor for each set. There are 3 problems on this page.
In this factors worksheet, students learn about common factors and greatest common factors. They then solve 3 questions in which they list the factors of each number and find the greatest common factor for each set of numbers.
Seventh graders examine Prime Factorizations, Multiples, and Factors. In this prime number, factorization, and multiples lesson, 7th graders identify greatest common factors and least common multiples. Students use problem solving skills to explore prime numbers, multiples and factorization.
Learners explore Euclid's method of finding  the GCF of large numbers.  In this algebra lesson, students investigate how Euclid's method works by using the integer divide function on the TI-73.
Students study division. In this math lesson, students search for numbers in the newspaper and use those numbers to divide. Students use divisibility rules to divide evenly.
Students study how to find prime numbers. They investigate the teachings of the mathematician Eratosthenes and apply his theory of prime numbers less than 100.
Sixth graders develop an understanding of Christmas traditions of other countries and well as the United States. They discover the meaning of other holiday celebrations and utilize computers and other technology as an integral part of the curriculum. Theories of multiple intelligences are also used.
In this equation worksheet, learners solve simple algebraic expressions containing one variable. Students solve the problems by using addition, multiplication, subtraction and division rules. Ten problems are provided on this one-page worksheet.
In this Algebra I activity, 9th graders solve problems that are based on pre-algebra and basic algebra skills, including divisibility rules, greatest common factor and least common multiple, and working with fractions and decimal numbers.  The one page interactive activity contains twenty multiple choice questions and is self checking. 
Ninth graders investigate integers.  In this Algebra I instructional activity, 9th graders illustrate the set of integers in Venn diagram, explore the definitions of opposite and absolute value, and perform integer calculations. 
Students explore the concept of exponents. In this exponents lesson, students make a human fraction bar using students from class to illustrate dividing powers of exponents. Students take notes from a presentation on exponent rules.
In this developing number sense worksheet, students play math games such as; working with remainders, solving problems, division brain power, and more. Students complete 6 activities.
For this scientific notation worksheet, students simplify 6 division problems.  Students use exponent rules and division rules to simplify each scientific notation expression.
Seventh graders explore the concept of integer addition. In this integer addition lesson, 7th graders tell stories involving addition and subtraction. Students walk on a number line given directions such as add 3 or add -2. Students play integer addition war or integer addition snap with playing cards.
Seventh graders determine the difference between prime and composite numbers. On a Website, they discover a method to identify all the prime numbers up to 100 and also complete several online activities. Once they have discussed the divisibility rules, they practice using them to decide which numbers provided by the teacher are divisible.
In this basic multiplication activity, students identify and describe patterns in a multiplication table. Then they use and apply mathematical reasoning to explore divisibility rules. Students also record their results in the chart provided on the last sheet.
Students explore the concept of extremely small numbers. They study an analogy comparing the millimeter, micron, and nanometer and then come up with their own analogy to define the differences in the three minute measurements. (Several other lessons are included in this plan.)
Learners answer a variety of questions using "Turning Point Clickers" connected to an interactive whiteboard. Plan is intended to accompany a chapter review of converting decimals, percentages, fractions, and ratio. They respond to questions as presented in a PowerPoint and enter their answers via the clickers. Questions cover statistics, integers and number sense. The PowerPoint is not included with the lesson, nor is a worksheet that is mentioned.
