Learners investigate the concept of multiplying fractions and use the inverse for doing division. They practice working the problems with scaffolding provided by examples with the teacher. The link is made to real life with the application of using pizza to represent fractions.
In this bedroom redecoration project, your young mathematicians become interior designers. They plan, draw, and determine finances for the project. They apply their knowledge of working with decimals, geometric shapes, and problem solving skills as they choose paint, flooring and furniture for the project.
Elementary mathematicians practice double-digit multiplication. They research the cost of various birthday party packages at a family recreation center using its website for cost information. They simulate the use of paper money and coins to determine what they will need to pay for the party. This lesson helps learners to get a handle on comparing numbers that contain decimals.
Learners explore the concept of scientific notation. In this scientific notation lesson, mathematicians discuss how multiplying by a power of 10 affects the decimal. They play Powers of 10 Yahtzee. Students roll a die five times and each time they roll, they are rolling a power of 10. Students win by getting the highest sum. Pupils discuss the differences between scientific notation and standard notation.
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.
Computing class members encounter use a digital learning tool called The Fraction Bar to multiply fractions with whole numbers. They do so by finding a given fraction of a number either on a number line or by calculating the answer with multiplication. Since it's always more fun to practice online, let your learners do this as a homework assignment!
Students recognize and generate equivalent forms of fractions, decimals, and percents. In this conversion lesson, students analyze sets of fractions to find forms of 'one' used in equivalent fractions. Students use models to find equivalency, convert, and compare among fractions, decimals, and percents.
This presentation covers how to perform the four basic operations when using decimal numbers. How to add, subtract, multiply, and divide decimals is the focus. Terrific slides that have clear examples and guidance are present throughout. This PowerPoint would be a great accompaniment to any middle school lesson on decimals. Very good!
Fifth graders practice a wide range of strategies for solving multiplication and division problems with whole numbers and decimal fractions. They interact with operations on decimals, relevant size and place value of decimals to three places and properties of operations with fractional numbers and integers.
Students access prior knowledge to round numbers and add decimals. In this mental math lesson, students share the book Betcha and calculate estimates for three jars based on the book. Students calculate money answers based on coins presented them. Students complete a worksheet and play a game.
