5. Circle the Leap Years.
We need to identify which years from the list are leap years. The rule for determining a leap year is:
- A year is a leap year if it is divisible by 4.
- However, if the year is divisible by 100, it is
not a leap year unless it is also divisible by 400.
#### List of years: 2020, 2021, 2022, 2023, 2024, 2025, 2026, 2027, 2028, 2029, 2030, 2031
-
2020: Divisible by 4 → Leap year
-
2021: Not divisible by 4 → Not a leap year
-
2022: Not divisible by 4 → Not a leap year
-
2023: Not divisible by 4 → Not a leap year
-
2024: Divisible by 4 → Leap year
-
2025: Not divisible by 4 → Not a leap year
-
2026: Not divisible by 4 → Not a leap year
-
2027: Not divisible by 4 → Not a leap year
-
2028: Divisible by 4 → Leap year
-
2029: Not divisible by 4 → Not a leap year
-
2030: Not divisible by 4 → Not a leap year
-
2031: Not divisible by 4 → Not a leap year
Leap years to circle: 2020, 2024, 2028

6. Circle the Leap Years.
We need to identify which years from the list are leap years. Using the same rule as above:
#### List of years: 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020
-
2009: Not divisible by 4 → Not a leap year
-
2010: Not divisible by 4 → Not a leap year
-
2011: Not divisible by 4 → Not a leap year
-
2012: Divisible by 4 → Leap year
-
2013: Not divisible by 4 → Not a leap year
-
2014: Not divisible by 4 → Not a leap year
-
2015: Not divisible by 4 → Not a leap year
-
2016: Divisible by 4 → Leap year
-
2017: Not divisible by 4 → Not a leap year
-
2018: Not divisible by 4 → Not a leap year
-
2019: Not divisible by 4 → Not a leap year
-
2020: Divisible by 4 → Leap year
Leap years to circle: 2012, 2016, 2020
