Scenario
The Three Little Piglets need to buy materials to make their houses. They go to the local Home Improvement store to purchase their materials. As an employee of the local Home Improvement store, the Three Little Piglets ask you where the materials are that they can purchase to build a house. You show them the materials and they see that they can only purchase straw, sticks, and bricks. Pig One buys a wheelbarrow full of straw. Pig Two buys a wheelbarrow full of sticks. Pig Three buys a wheelbarrow full of bricks. At the store, the store manager tells the pigs that it will be a lot easier to carry their materials home if they put them into groups and secure them tightly. You will determine how many pieces of straw, sticks and bricks each pig purchased. You will determine how each pig bundles their materials and how much is in each bundle. You will write a letter to the store manager about how your way of bundling each pig's materials is efficient.

You have been asked, by the Service Club at your school, to pass out flyers on recycling in your county. Because your county is big, it will take you a while to reach every house. To make your flyers, you need lots of paper. Each ream of paper has 500 sheets in it. You will need to determine how many reams you will need to make your flyers. You will also submit a flyer to passed out to the county.

***NOTE

When this PBL was originally created NC had not yet adopted it's new standards. This can be adapted to the new standards, if needed.

This is from Tools for NC Teachers. Students explore the value of a group of one type of coin and consider how changing the value of the coins changes the value of the group. This is remixable.

This short video and interactive assessment activity is designed to teach third graders about forming largest and smallest numbers (even and odd).

This short video and interactive assessment activity is designed to teach fourth graders about forming the largest or smallest possible number.

This task gives children an opportunity to subtract a three-digit number including a zero that requires regrouping. The solutions show how students can solve this problem before they have learned the traditional algorithm.

Students partner up and take turns guessing each others decimals. Students must read the decimals correctly and match them up with the correct decimal in standard form.
