They will be provided with an office plan to calculate the perimeter of the building to then calculate how many holiday lights will need to be purchased and its total cost for each. They will need to read several ads and decide which product would be the best for the property. The students will be asked to assist a business/property owner in purchasing holiday lights for his property. In this MEA, students will work in collaborative groups to solve real-world, multi-step problems with whole numbers and decimals by using different mathematical operations such as addition, subtraction, multiplication and/or division. They will report their findings and reasons by writing letters to the client. After, they will add the total costs of the playroom and the storage closet. They will need to decide if to use the same floor tile or different from the playroom and the additional cost of the storage closet.
The "twist" will be that the client now needs to include a storage room for some of the playroom's equipment. They will also need to calculate the costs of installing the floor tiles using the given measurement of the playroom and the floor tiles. They will need to take certain factors into consideration when making their rankings. Students will be asked to rank the different floor tiles for the playrooms in activity centers throughout community parks.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. The students will need to reevaluate the tile companies as well as recalculate the total costs to include tile for the bathroom. An additional twist will be that the homeowner has decided to tile his bathroom as well. A twist is added to the problem when one of the tile companies goes out of business, but two new companies are added.
Students will need to read a data table, rank the tile companies from best to worst, calculate the amount of tiles needed according to the area, and determine the total cost to retile the kitchen and family room.
The students will be asked to assist a property owner, who is planning to retile his kitchen and family room floors, with purchasing the best quality tiles for the least amount of money. In this MEA, students will work in collaborative groups to solve multistep problems with whole numbers and decimals by using different mathematical operations such as addition, subtraction, multiplication and division.
