Explore decimals with upper graders. They solve problems from their textbook involving decimal multiplication. Afterward, as a class, they check their answers by comparing them to those projected with an overhead projector.
In this fractions instructional activity, students read an instruction sheet on the procedure for multiplying simple fractions. All steps are illustrated. There are no problems to solve.
Students convert between decimals, percents, and fractions. In this conversion lesson, students are shown a demonstration on the board by the teacher. Then they complete a 10-problem worksheet individually. An answer key is included.
Students study how to change decimals into fractions by discussing the examples in the lesson. They then work independently on the worksheet to change the decimals into fractions.
Students are introduced to how to change fractions into decimals by viewing the examples provided. They then begin working to solve the problems included in the worksheet independently.
Pictures, number lines, decimal equivalents, or Cuisenaire rods can be used to show insight into the meaning of multiplying fractions.Here, Alisa drinks 3/4 of 1/2 liter of juice. To find the total volume of the juice that Alisa drank, learners demonstrate with an appropriate math tool, their work with multiplying fractions. The commentary section contains examples of the solution shown in four different ways. 
One of the most common, everyday applications of math is dealing with money. This single problem calculating how much change Margie receives is more involved than it appears at first glance. An understanding of how fractions and decimals relate to dollars and cents is essential as values are multiplied and subtracted. A great practice problem or short assessment to supplement your unit on fractions and decimals.
The real value of education is highlighted in more than one way on a worksheet designed to not only add, subtract, multiply, and divide decimals to hundredths, but also to address the correlation between higher pay with accomplishing higher levels of education. The chart on the student worksheet shows the weekly income of four people with varying amounts of education completed. The three follow-up questions ask 5th graders to compare and find the difference between the incomes. Although a lesson plan is not included, the commentary and solutions page gives teachers the relevant information necessary to incorporate the activity in the classroom.
A great way to help struggling learners with long division is to provide graph paper. These worksheets provide handy boxes to help kids keep all that great work in the right order. It also provides over 20 worksheets to help pupils practice division, multiplication, and adding and subtracting decimals. 
Mathematicians need to know that not all numbers are rational. We approximate irrational number with rational numbers. That is why a calculator may be misleading. This task give learners an opportunity to see how rounding a number and then multiplying it is not the same as multiplying a number and rounding it. 
Kids love to cook! What is a better place to learn mixed numbers than with a recipe? It is up to learners to decide how they want to divide this recipe in half. They may choose to model the mixed number and then divide the model by two. Maybe it is easier for them to graph on a number line and then mark the half-way point. Or a straight computation of multiplying by one half could be their choice. Any way your number crunchers dice it up, they need to use critical thinking in order to complete this exercise.
This is a good Common Core question that relates inflation to operations with decimals and rounding. Young learners are asked to find out if an amount of money can purchase the same amount of movie tickets in 2012 as it did in 1987. They then must decide how much more money is needed to purchase the same amount of items. Can be used as a class activity or as an independent assignment.

Sal writes the number 63.15 in word form. He writes each number in a different color, and then writes the corresponding word in the same color to clearly demonstrate that 63.15 is the same as sixty-three and fifteen hundredths.
Help mathematicians convert fractions to decimals and vice versa through these exercise sets. First, they write out nine fractions as decimals. This is really a practice in place value, as all the denominators here are 10. One of them requires multiplying to become an equivalent fraction with the denominator of 10. Next, they write nine decimals as fractions, also with 10 as denominators. Some of these need simplifying, and scholars are prompted to do this in the specific equations. Learners repeat this entire process with 100 as the denominator. The examples here provide great guidance and the self-prompting steps in each problem are extremely helpful.
Students access prior knowledge of long division and multiplying decimals.  For this dividing decimals lesson, students view a demonstration of how to move decimals when dividing.  Students complete a dividing decimals worksheet. Students compare decimals to fractions.
Practice dividing decimals with your math class. They will review long division skills and review how to move the decimal place during division. Then they complete worksheets to demonstrate their comprehension of this skill.
In this multiplying decimals worksheet, students multiply tenths, hundredths, thousandths, times one thousand. Students solve 45 problems.
In this multiplying decimals using the zero property worksheet, students multiply times ten, one hundred, and one thousand. Students solve 45 problems.
