Recite the seven days of the week in order and correctly name today.
A week has seven days: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday. Each day has its own name, and they always come in the same order.
Once you learn the order, you can always say what day comes next, no matter what day you start on.
Mastery looks like: They recite all seven days in order without help and correctly name today.
Common stumbles: Skipping or swapping Tuesday and Thursday is extremely common; slow, repeated practice fixes it over time.
