Find the product of numbers that have decimals. First, ignore the decimals and multiply the integers. Second, count the place values of the decimals for each value given. Third, add the values together. Fourth, place the decimal in the appropriate place.
Students review concepts of fractions as a transitions into learning to multiply decimals. In this multiplication of decimals worksheet, students complete guided practice worksheets with teacher direction.
Young scholars demonstrate how to multiply decimals. For this multiplication lesson, students view a demonstration on how to multiply decimals and practice this skill independently.
For this multiplication worksheet, learners play a game with 2 number cubes or dice where they substitute decimals for the numbers on the cubes. Students multiply the decimals together then find the corresponding product on a 5 by 5 game board. Learners must get 5 products in a row to win. The students are multiplying decimals where the factors are expressed as tenths and hundredths. Learners complete 3 high level short answer questions after the game.
In this decimal multiplication worksheet, learners complete a set of 12 problems, multiply decimal tenths. Answers are included on page 2.
In this multiplication of decimals activity, students complete 6 sets of problems. The first two sets of ten problems involve whole number computation. The final four sets involve decimal multiplication. There are a total of 59 questions, 58 are short answer, one is multiple choice.
Explore all things decimal in this thorough series of introduction activities. Including scripting for the teacher and detailed descriptions and examples, the plan begins by reviewing the basics of place value and writing fractions as decimals, works through rounding, adding, subtracting, multiplying and dividing numbers with decimals, and culminates in word problems and linear equations involving decimals.
In this math worksheet, students practice multiplication of decimals. Students begin by multiplying whole numbers by decimals, then decimal numbers by decimals, up to the thousandths place. The problems are written both in horizontal and vertical form. Multiplication (mental) of decimals by 10, 100 and 1000 are also included. Hints and clues are provided.
You are used to teaching repeating decimals with bar notation that keeps us from writing that number over and over again; now teach what the over and over again represents. This activity allows your mathematicians to explore the infinite decimal and see how different calculations get us close to the original number, but not quite exactly on it. The lesson includes commentary and a solution key to help guide the activity.
Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks at these problems and tries to draw conclusions about why certain numbers are easier to work with mentally, leading to interesting insights into our number system and powers of ten.
A very lethargic women describes the process by which one can multiply decimal numbers. Multiplying decimals is just like multiplying whole numbers. Observe the instructor explain her actions as she multiplies two decimal numbers together and explains how to place the decimal in the answer. Don't forget the decimal!
Once young mathematicians understand how easy it is to multiply and divide by 10, they'll be hooked! They complete four sections of 12 problems each, all involving this skill. First, scholars find the product of various whole numbers multiplied by 10. Next, they divide numbers by 10, all of which require decimals. The next two sections have missing factors and missing dividends. There are two examples to get them started, and you may consider modelling one from each section before kids do this on their own.
In this math worksheet, students complete a page that provides a step by step explanation of how to multiply decimal numbers to the hundredths place. Students answer 8 questions and may choose some extension activities with a partner.
Put your learners' decimal skills to the test with these five word problems. With space for students to write their work, the word problems contain addition and multiplication problems with money and measurement units. Use this resource as a quiz or an in-class activity to fully assess your class's comprehension.
A rational number is a ratio of two integers. Discuss with your class how to convert the rational numbers of repeating decimals to fractions. A good commentary on letting x equal the repeating decimal and multiplying each side of such equation by a power of 10 or 10r, where r is the repeating segment.
Multiplying decimal numbers isn't that much different than multiplying whole numbers. If you need a little extra support, this video may help. Sal shows how to multiply 23.12 by 0.5. He takes care to line up the decimal points, regroup, and place the decimal in the proper place when he finishes his computation.
Divide decimals. Watch as Sal explains how to divide 1.03075 by 0.25. He provides a step-by-step process that is easy to follow, clear, and well-organized. Note: This would be great for a teacher prepping for a math lesson or as supplemental material to show in class.
Have your young mathematicians complete this practice problem along with Sal. To solve this thinking problem, they will need to multiply decimal numbers in order to determine the cost of 14.6 gallons of gas when gas costs $2.70 per gallon.
It's all about decimals in these word problems, which have scholars apply math to scenarios they will likely come across later in life. Working with multi-digit numbers and decimals to the hundredths place, learners must determine the operation for each of six problems and show their work in the designated place. They use subtraction, multiplication, and division to solve these, and can reference the two examples if they need to.
Sal takes out the big guns - or in this case, big calculator - in this video, which carries the concept of significant figures even further. Sal shows how to multiply and divide significant figures using both electronic and handwritten calculations.
