12
to make pancakes. She used 150 g of four for the pancakes. Find the amount
of four she used to make muffins
Answers
Answer:
Draw a diagram and write a multiplication equation for each situation.
A batch of cupcakes requires 112 cups of flour. How many cups are needed for 3 batches?
A batch of bread requires 3Â cups of flour. How many cups are needed for 12 of a batch?Â
A batch of rolls requires 212 cups of flour. How many cups are needed for 112 batches?
A batch of cookies requires 2 cups of flour. How many batches can you make with 8 cups of flour? Here are a diagram and a division equation that represent this situation:
8÷2=?
Draw a diagram and write a division equation for each situation.

A batch of bread requires 3Â cups of flour. How many batches can you make with 2Â cups of flour?Â
A batch of rolls requires 212 cups of flour. How many batches can you make with 412Â cups of flour?
IM Commentary
The purpose of this task is to help students extend their understanding of multiplication and division of whole numbers to multiplication and division of fractions. In grade 5, students
multiply two fractions together and learn that a fraction times a number can be interpreted as that fraction of the number,
divide two whole numbers with a non-whole number quotient, and
divide a whole number by a unit fraction and a unit fraction by a whole number.Â
Notably, all of the division students do in grade 5 can be supported by an understanding of a whole number of groups. The big shift in grade 6 is that students tackle division contexts that involve a fractional number of groups.
The task does not ask students to find the product or quotient since the task is more about learning how to represent the situation, but teachers might choose to ask students to find or estimate the answers, if desired.
This task helps students see how to represent How Many Groups/What Fraction of a Group? contexts with division equations. It's designed to be used along with the task How Much in One Batch? which covers the How Much in a Group? situation.
To offload some of the tedium of drawing diagrams so that students can focus on thinking about sizes and numbers of batches, teachers might offer some printed templates for students to work on.
