Activities
-
Harry's Potion Ingredients
Imagine you are brewing a potion with Harry Potter. Write down a list of 5 potion ingredients and assign each ingredient a numerical value (e.g., unicorn horn = 10, dragon scale = 5, etc.). Add up the values of the ingredients to find the total value of the potion.

Eighth Grade Talking Points
- "Arithmetic is the branch of mathematics that deals with numbers and basic operations like addition, subtraction, multiplication, and division."
- "In the Harry Potter books and movies, many magical elements can be related to arithmetic. For example, the values assigned to potion ingredients, calculating scores in Quidditch, or managing money while shopping in Diagon Alley."
- "Understanding arithmetic concepts and applying them to real-life situations, even in a magical world, can help us solve problems and make sense of the world around us."
- "By practicing arithmetic, we can improve our problem-solving skills and become more confident in handling mathematical challenges."
- "Remember, arithmetic is the foundation of more advanced math topics like algebra, geometry, and calculus. So, it's important to have a strong grasp of arithmetic."
