Entry Events

Events that will be used to introduce the project to students

Mystery Shopper Budget Mission

A surprise shopping mission is presented where students receive a mystery budget. They must determine what and how much they can purchase for their virtual marketplace while using multiplication to calculate costs and make wise purchasing decisions. Students will lean forward with anticipation as they uncover what they can 'buy' with their budget.

Marketplace Math Mystery Box

Students receive a mysterious box filled with 'items' they could sell in their marketplace. Each item requires them to use multiplication to determine pricing, tax, and discounts. This interactive and tangible approach connects math problems directly with real-world applications while sparking creativity in product planning.

Pop-Up Market Day Event Planning

Students are tasked with planning a virtual 'pop-up' market day where they will sell items using multiplication to set prices and calculate potential earnings. The entry event begins with successful entrepreneurs sharing their stories, inspiring students to think about how they can apply math skills in unique ways to manage and grow their marketplace.
