About this lesson
Students apply math skills to explore the impacts of climate change on the geography of the Jersey Shore.
Inquire: Students watch a video introducing an overview of climate change.
Investigate: Students round decimals and apply multi-digit subtraction to calculate how much the sea level has risen at the Jersey Shore.
Inspire: Students explore a visual representation of the potential sea level rise on different locations at the Jersey Shore.

How to edit these materials (video)Teaching tips
Suggestions
- This lesson should be taught in a 4th grade Math Unit that focuses on Number and Operations in Base Ten or at the beginning of the school year when reviewing concepts of Place Value, Rounding, and Addition/Subtraction.
- This discussion may bring up anxiety for some students. Consider using resources from the Climate Anxiety: SEL Resource for Teachers including a template to inform caregivers of the topics in the unit and sentence frames for discussions.
- This lesson introduces the concept of social justice and engages students in reflection.
- When inputting the total increase in sea level rise using the Climate Central: Coastal Risk Screening Tool, different coastal areas of the Jersey Shore (e.g., Asbury Park, Seaside Heights, Sea Isle) can be searched to facilitate reflective conversations among the students.
Prerequisites
- This is lesson 1 of 3 in our 4th grade Unidad de matemáticas: Erosión costera.
- The information collected throughout this lesson will be used in Lessons 2 and 3. Students should keep their materials (e.g., Graphic Organizers, T-Charts, and Exit Tickets) from each lesson because they will need them to complete Lesson 3.
- Students should have a basic understanding of cause and effect prior to this lesson.
- The last step of the Inquire section will require the teacher´s guidance in converting mm into meters if the students have not been exposed to unit conversion in the metric system.
- Students should have a working understanding of the following mathematical concepts: Place Value, Tenths, Hundredths, Estimating, Rounding, and Subtraction.
- Pre-watch the video, “Cambio Climático,” and identify stopping points to give the students an opportunity to jot down information on their graphic organizer.
Differentiation
- Teacher should turn on the Closed Captions for all the videos in this lesson.
- It is possible to modify the graphic organizers “Causa” and “Efecto” in the following ways:
- Limit the number of answers
- Work in pairs or groups
- Provide a pre-filled graphic organizer with the causes and/or solutions and ask students to identify a limited number of answers
- Group and/or partner work should be scaffolded as 1 expert: 1 novice to facilitate peer scaffolding.
- Use chart paper to model how to fill out the first set of information on the graphic organizer.
- Teachers or students can color code to differentiate the cause from the effect.
From the scientist review
Los estudiantes aprenderían a utilizar operaciones matemáticas básicas para calcular datos climáticos y el grado de aumento del nivel del mar en la costa de New Jersey. Esta lección pasó nuestros criterios de credibilidad para la ciencia cuando la revisamos.
Students will learn how to use basic mathematical operations to compute climatic data and the extent of sea level rise on New Jersey's shoreline. This lesson passed our credibility criteria for science when we reviewed it.
