You have one pie and then you cut it into six equal pieces. Each child gets 2 cookies--the quotient. You can use the division organizer we used in the previous lesson if it helps you. When we carefully look at related division and multiplication problems, we can see the dividend of the division problem is the product of the related multiplication problem.
What is the fraction that represents the number of pieces in the tin? This leftover number is called a remainder, and it is written as part of the quotient. We then count up how many rectangles we were able to fill with five items.
Students can also be given a multiplication sentence with an unknown variable and then write the related division sentence. The lesson is designed to use basic division facts to help students develop a conceptual understanding of division as opposed to just using algorithms to solve problems.
This problem, FYI, is a little too hard for second or perhaps even third grade, but if we had 4 children sharing 15 cookies so that the cookies could be shared by making halves and quarters the problem would not be too hard for second grade.

Divide the class into small groups for an activity. Once students are finished creating their word problems, have them exchange with each other and write a division equation and related multiplication equation. Using the observations made during the index-card activity and on the checklist, you can identify those students who need additional support in small groups.
What multiplied by 9 equals 63? Explain that four prize bags need to be made. You wind up multiplying the numerator and denominator by the same number to make new equivalent fractions.
The top number, the numerator, represents how many you have. Where necessary, provide verbal prompting to redirect thinking.
Pose timely word problems to students that show the relevance of division in their everyday lives.Suggested words include: dividend, division, divisor, estimation, grouping division models, sharing division models, and quotients. Expansion: Students can take any of the problem-solving cards used earlier in the lesson or student-created problems and write related multiplication sentences with an.
Three ways of thinking about division with remainders. How does a remainder affect the answer to a word problem? In different problems, the remainder has different affects on the answer. Consider these examples: The names of the parts of a division problem are dividend ÷ divisor =. When you write that one piece as a fraction, you will write 1/6.
If you write the whole pie as a fraction, you write 6/6, since it has all six pieces.
The top The numerator is the first number in a division problem (dividend). The denominator is the second Different Ways of Writing Fractions Let's look at equivalent fractions first.
