Introduction

Good morning, math adventurers! Today, we have an exciting challenge for you. Are you ready to go on a treasure hunt? In this lesson, we will be learning how to solve division problems that have remainders. But instead of just solving problems on paper, we will be using our math skills to search for hidden treasures around the classroom.

The Rules

• You will be working in pairs.
• Each pair will receive a map with markers that lead to different locations in the classroom.
• At each location, you will find a division problem and a clue.
• Solve the division problem to get the answer to the clue.
• Use the clues to find the location of the next marker on your map.
• The first pair to find all the markers and reach the treasure chest wins!

Getting Started

Before we begin our treasure hunt, let's review how to do division with remainders.

When we divide, we may have some numbers left over that do not fit evenly into our groups. These leftover numbers are called remainders.

For example:

• 15 ÷ 4 = 3 with a remainder of 3
• 20 ÷ 6 = 3 with a remainder of 2

To find the remainder, we subtract the quotient (the answer to the division problem without the remainder) multiplied by the divisor (the number we are dividing by) from the original dividend (the number we are dividing).

For example:

• 15 - (4 x 3) = 3
• 20 - (6 x 3) = 2

Now that we have reviewed the concept, let's get ready to go on our treasure hunt! Put on your math caps and let's go!
