In this lesson, students will address the following real-world problem of sand dune erosion while integrating Engineering Design concepts:

Florida’s coastline has been ravaged by winds from hurricanes, resulting in damage to sand dunes and oceanfront properties. Your mission is to design the most effective barrier that would limit the amount of sand displaced from our tall sand dunes and prevent further damage to oceanfront buildings. Your designs can help us save the sand dunes before they are blown away!

In this STEM build, students will use problem solving skills and teamwork to model an effective way of slowing down beach erosion caused by the ocean. Students also will practice sharing their results through PowerPoint presentations.

In this lesson, students will learn how different variables (mass, friction, and force) affect the motion of an object.

In this Engineering Design Challenge lesson, students will create a model beach and use different materials to find a solution to slow down the erosion process.

In this lesson, which focuses specifically on the elapsed time portion of the standard, students work in small groups in a "race" to solve real world problems involving time.

In the "twist," students are provided with more information including customer service rating of transportation as well as an additional choice. Students must also calculate the arrival time when given the departure time and the elapsed time to determine if the team will be arriving in time. Additionally, students learn about an option to have a chance to win a drawing based on the cost of the transportation option selected.

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. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

This MEA asks students to take on the job of a tennis pro and decide which factors are most important in choosing a facility to take tennis lessons. Students will perform math calculations, create a two-column table for hours and minutes, develop a procedure to rank facilities, and provide written feedback through letters to a parent whose child needs group tennis lessons and writes letters to ask for advice. They will rank their choices from "best to worst" tennis lesson facilities. Students will provide a detailed written explanation for how they decided to rank factors and their solution for rating tennis lesson facilities.

This activity requires students to apply their knowledge of unit conversions, speed calculation, and comparing fractions to solve the problem of which water park their class should choose to go on for their 5th grade class trip.

This Model Eliciting Activity (MEA) asks students to develop a procedure to select a pickle brand for a sandwich shop. Students will need to consider appearance, texture, price, flavor, length of shelf life, and estimating shipping costs. In the second portion of the problem statement, the students will need to trade off what they have previously considered and give more worth to the estimated shipping costs, while adding three more brands for consideration. The students will complete a culminating activity of making a commercial to advertise their selected brand. Student will need to work together and use the standard conventions of writing to write and perform their commercial for the other groups.

Learn about sales tax as Malik tries to buy his favorite candy from the store in this short video.

This task is designed to help students focus on the whole that a fraction refers. It provides a context where there are two natural ways to view the coins.  While the intent is to deepen a student's understanding of fractions, it does go outside the requirements of the standard. 

The purpose of this task is for students to solve multi-step problems in a context involving a concept that supports financial literacy, namely inflation. Inflation is a sustained increase in the average price level. In this task, students can see that if the price level increases and people’s incomes do not increase, they aren’t able to purchase as many goods and services; in other words, their purchasing power decreases.

When a division problem involving whole numbers does not result in a whole number quotient, it is important for students to be able to decide whether the context requires the result to be reported as a whole number with remainder (as with Part (b)) or a mixed number/decimal (as with Part (c)). Part (a) presents two variations on a context that require these two different responses to highlight the distinction between them.
