This is a great opportunity to learn about average! The average, also known as arithmetic mean or mean, is the number obtained by adding two or more numbers and then dividing by the number of numbers. For example, if you received 3 stars in 2 lessons, the Average Stars is calculated by adding the total of stars, 6, and dividing it by the number of lessons, 2. So, the Average Stars is 6 ÷ 2 = 3. Similarly, if you received 12 stars in 5 lessons, the average is 12 ÷ 5 = 2.4. This means that, on average, you earn 2.4 stars per lesson!
