Objective
By the end of this lesson, you will be able to apply calculus concepts to solve Christmas-themed mathematical problems.
Materials and Prep
- Paper and pencil
- Calculator (optional)
- Basic understanding of algebra and geometry
Activities
-
Activity 1: Santa's Sleigh Speed
Calculate the speed of Santa's sleigh using calculus. Assume that Santa travels a distance of 500 miles in 2 hours. How fast is Santa's sleigh going in miles per hour? Use the formula speed = distance / time.
-
Activity 2: Reindeer's Acceleration
Determine the acceleration of one of Santa's reindeers. Given that the reindeer starts from rest and reaches a speed of 30 meters per second in 5 seconds, calculate the acceleration using the formula acceleration = (final velocity - initial velocity) / time.
-
Activity 3: Present Wrapping Optimization
Imagine you are wrapping rectangular presents for Santa. You have a roll of wrapping paper that measures 10 feet by 3 feet. Calculate the maximum number of presents you can wrap using the entire roll of wrapping paper. Assume that each present has dimensions of 1 foot by 1 foot by 1 foot.
Seventh Grade Talking Points
- "Calculus is a branch of mathematics that deals with rates of change and accumulation."
- "It helps us understand how things change and how they accumulate over time."
- "In Activity 1, we are using calculus to find the speed of Santa's sleigh by dividing the distance he travels by the time it takes him."
- "In Activity 2, we are calculating the acceleration of one of Santa's reindeers by subtracting its initial velocity from its final velocity and dividing by the time it takes to reach that speed."
- "In Activity 3, we are optimizing the use of wrapping paper by finding the maximum number of presents we can wrap using the given dimensions."
