Lesson Plans
- Huff and Puff: A Lesson Focused on the Force of the Wind: In this lesson students will be exploring the force of wind and its affect on objects. Students will use the engineering design process to sketch, build, and assess how their structure withstands different forces of wind.
- Taking Flight: Students will explore airplanes in this project-based lesson/unit with multiple lessons that are all tied to a final project.
- Wilbur's Pig Pen Addition: Students will explore the fundamentals of adding measurements involving shapes. Students will practice measuring the sides of rectangles and engage in an extended problem-solving task that includes adding to find the distance around rectangles.
- Animal Sanctuary Engineering Design Challenge: This Engineering Design Challenge is a hands-on investigation in both math and science. Students will be able to use prior knowledge and problem solving skills to solve non-routine problems and real-world situations, using mathematical and scientific models. It is a great way to introduce your students to real-world problem solving. Students will be engaged in hands-on learning by designing and creating an enclosure for zoo animals. Both math and science standards have been incorporated for an integrated lesson.

Professional Development
- What Does It Mean To Measure?: This is a professional development session from the Learning Math series from Annenberg. Learners will begin to explore the questions "What can be measured?" and "What does it mean to measure something?" Learners identify measurable properties of objects such as weight, surface area, and volume, and discuss which metric units are appropriate for measuring these properties. Learners will also learn that measurement is, by its nature, approximate. Finally, learners will consider how to make measurements using nonstandard units. This session features a number of problems for learners to solve and open-ended questions to discuss, videos that demonstrate measurement techniques, and an interactive activity that asks learners to construct shapes using different size triangles to foster understanding of area and perimeter. There are also nine homework problems in which learners are asked to generate different measurements, graph measurements, and evaluate the appropriateness of the measurements generated using a data chart. Many of the professional development activities can be used directly in the classroom.
Teaching Idea
- Big as a Baby Whale-SeaWorld Classroom Activity: In this activity, students will create life size chalk drawings of J.J. the gray whale to discover the size and growth rate of juvenile gray whales.
