Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.

Standards for Mathematical Practice: CCSS.MATH.PRACTICE.MP2 Reason abstractly and quantitatively

Summary- 100 hungry ants are on their way to a picnic in a straight line and decide to break up into smaller lines along the way in order to arrive faster to the picnic. They decide to shorten their lines four times before they finally arrive at the picnic and realize all the food is gone while they wasted time breaking up into shorter lines.

Rating-***** this is a great book to look at multiplication or division for third graders because the book breaks down the number 100 various ways. It is very interesting and has a rhyme scheme to it that grabs readers and the ending is unexpected and a great way to open up discussion.

Classroom Ideas/Lesson Ideas: 

Students can be asked to explain how the ants separated and communicate their reasoning by using clear language. After going through each row the ants made we can take it a step further and ask them how to organize the 100 ants into different number of rows such as 11, etc.
