This task may be implemented individually, in small groups, or in a whole-group setting. If the task is given in a whole-group setting, the teacher should ask each student to explain his or her thinking and strategy.
The teacher provides the student with the Whole Numbers Divided by Fractions worksheet and asks the student to create a story problem to match the expression and use a visual fraction model to determine the quotient.
The student may choose to complete this task by writing the story context first and then solve using a visual fraction model or solve using a visual fraction model before writing the story context.
Examples of Student Work at this Level The student attempts to divide 5 by but is unable to do so even with prompting. Attempts to write a story context but does not attempt to use a visual model.
Writes the word problem as addition, subtraction or multiplication and cannot find the quotient. Models the expression but makes an error. The context does not show a whole number divided by a fraction. Questions Eliciting Thinking Can you think of a situation where you have five of something being shared?
Could you write a story to match that? If I have two cookies and I want to give of each cookie to some friends, how many friends will get of a cookie?
What would that visual model look like? Did you show the five wholes? How many fourths will there be? How many fourths are there in one whole?
Step 2: Write one partial fraction for each of those factors. Step 3: If your expression is Improper, then do polynomial long division first. And we can now write our partial fractions: x 2 +15 (x+3) 2 (x 2 +3) = 1 2(x+3) + 2 (x+3) 2 + −x + 1 2(x 2 +3) Phew! Lots of work. But it can be done. SOLUTION: Write the expression without using a fraction bar? Algebra -> Numeric Fractions Calculators, Lesson and Practice -> SOLUTION: Write the expression without using a fraction bar? Log On Algebra: Numeric Fractions Section. Solvers Solvers. the expression No fraction bar. use properties to write the expression more efficiently.” The result may not look simple. Students simplify a fraction by dividing common factors to provide a foundation for dividing powers with the same base by expanding them. _____ Exponents and Division.
How could you show this in a model? Instructional Implications Provide clear instruction on how to use a visual fraction model to solve division problems involving a whole number divided by a fraction.
Model for the student and make clear how dividing a whole number by a fraction results in a quotient greater than the dividend whole number. Allow the student to use pattern blocks or fraction circles to model dividing whole numbers by fractions.
Continue to provide opportunities for the student to work on writing story contexts that show division of a whole number by a fraction.
Additionally, allow the student practice in solving division by fraction problems using a visual fraction model.Please use this form if you would like to have this math solver on your website, free of charge.

Practice Title: Scott Foresman Addison Wesley, enVision Math Author: Pearson Scott Foresman. process applies to the division of fractions, and when used in combination with fraction models, it helps students gain meaningful understanding of dividing fractions.
Simplify any Algebraic Expression If you have some tough algebraic expression to simplify, this page will try everything this web site knows to simplify it.
No promises, but, the site will try everything it has. A Write a division expression and draw a model to represent the problem. • Divide a whole number by a fraction. • Model division with manipulatives, diagrams and story contexts.
vabuoc LaRy There is no new vocabulary. 56 L6: Understand Division with Fractions (). For example, suppose you’re asked to write an expression for “the sum of twice a number and six.” Although any letter works, in this example, an “n” will be used.
Determine whether the problem involves a multiplication or division operation.
