Find Multiplying Decimals educational ideas and activities
Students create a "metric machine" to convert metric units. In this converting metric units instructional activity, students multiply and divide by powers of ten. Students view a video, fill a jar with skittles and M&M's, and complete problems with milligrams and kilograms.
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.
Marbles to learn math? What fun! Discuss the rules of multiplication and division when applied to whole numbers, decimals, and fractions. Small groups use6 marbles to design different types of multiplication and division problems, and explain why it is multiplication or division.
Eighth graders examine how to translate and convert between fractions, decimals, percents, powers, and scientific notation. They observe the teacher solve examples of a variety of problems, and independently complete a table that compares decimals, percents, and fractions.
Ninth graders observe and demonstrate translating between equivalent representations of the same number. They observe the teacher model examples of converting percents to decimals, fractions to decimals, fractions to percents, and comparing decimals, percents, and fractions. Students independently solve examples of converting numbers.
Students solve real-world problems related to medical careers. They use graphical representations as part of the problem-solving process and work with fractions, decimals, exponents, and metric measurement. A demonstration is included to help visualize the problem and solution.
Students explore the concept of fractions, percents, and decimals. In this fractions, percents, and decimals lesson plan, students make a log of how they spent a typical day during the summer. Students find the percentages of a certain activity in relation to the whole day. Students convert between fractions, decimals, and percents.
Inject fun into your math review! Pupils review basic math operations with decimals as well as addition and subtraction with simple fractions. In this number operations lesson, students work in groups to create a game for the math skill they are given. Students share their ideas, decide on one and create the game. This could be used as a cumulative assessment.
Ninth graders translate between fractions, decimals, percents, exponential expressions, and scientific notation. They discuss the importance of converting between forms of the same number, observe the teacher model a variety of examples, and independently complete a worksheet.
In this scientific notation worksheet, 9th graders solve and complete 8 various problems related to exponents and writing scientific notation of numbers. First, they write whole numbers, decimals, and other types of numbers in scientific notation. Then, students convert each of these numbers listed in to scientific notation. Finally, they simplify two problems and express their answers in scientific notation.
Sixth graders work with equivalent fractions, decimals, and percents. In this equivalency lesson, 6th graders participate in a number of activities aimed at increasing their understanding of equivalent expressions. They form a human equivalent problem, play the "Identical Twin" game, and create word problems before taking an assessment.
For this summer school math worksheet, students complete 100 multiplication problems in which 3 digit numbers are multiplied by 2 digit numbers. Students also solve 100 problems in which simple fractions with unlike denominators are added and subtracted. Then students solve 100 division problems with decimal or whole number 2 digit divisors.
Fifth graders determine how to convert fractions, decimals, and percents. For this conversion lesson, 5th graders use an on-line applet to practice making these conversions. They review how to make the conversions in a whole class lesson before accessing the "Fraction Four" applet. They work with a partner to play the web site game.
