Recommended Grade Level:  2nd Grade

CCSS.MATH.CONTENT.2.OA.A.1
Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

CCSS.MATH.CONTENT.2.OA.C.4
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.



This book centers around a swim team comprised of different types of sharks that is presented with a challenge of swimming 75 laps by the end of the week.  If they swim these laps then they’ll have the opportunity to go to a swim camp the city will pay for.  The dilemma stems from the fact there are only 4 days left in the week, 6 team members, and 75 laps seems like a daunting task.  The swim team figures out that if they use all their abilities collectively then they can achieve their goal and get to the swim camp.  There’s a lot of math to be done but the prize of swim camo is too great to be concerned about a large number of laps they can divide amongst themselves!


Rating:  5 Stars!

Classroom Ideas: 

1.     This book can be used in a variety of ways.  One way is to introduce the idea of regrouping and what that means.  The book speaks about place values and it’s a good way to make regrouping a fun read.
2.    This can also be a classroom activity that is presented with different numbers. After reading the book then the class can be divived evenly and given a task where they figure out how many of each thing they’ll do to achieve a particular result.  For example, if we have a contest that states the class needs to bake 86 cupcakes and each student has an oven that fits 8 cupcakes at a time.  What can we do to achieve this goal?  This can be something the kids figure out themselves.  At the end we can go over the different strategies that each group came up with to figure out their dilemma.

    Hi,

    I really like this book. I think it is great to use to teach division. As there is 75 laps that need to be completed by the end of the week and only 4 days left. When constructing a lesson plan you can develop many different problems with division such as, there is 75 laps that need to be completed in a week and Monday- Wednesday 25 laps were completed, how many laps are left to complete and how can it be divided evenly into the rest of the days of the week. Overall, I think this book is great to plan a math lesson with.
