Time Units and Calendar Facts

Know the number of seconds in a minute and the number of days in each month, year, and leap year

Lesson

Set out your lesson

Use month lengths and the complete Gregorian leap-year rule.

Before teaching

Activity

Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.

Policy

Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.

Printer, credit, and teaching notes

Use a fixed example year, not a guessed current year. The month table is a teaching reference; hide it for recall. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.

partial: Know the number of seconds in a minute and the number of days in each month, year, and leap year
Canonical every-four-years wording has exceptions; preserved but not taught as an absolute. Fixed-year reasoning replaces the unspecified this year assessment.
partial: State that there are 60 seconds in a minute
Canonical every-four-years wording has exceptions; preserved but not taught as an absolute. Fixed-year reasoning replaces the unspecified this year assessment.
partial: Name the months and state the number of days in each
Canonical every-four-years wording has exceptions; preserved but not taught as an absolute. Fixed-year reasoning replaces the unspecified this year assessment.
partial: Explain that a leap year has 366 days and occurs every 4 years
Canonical every-four-years wording has exceptions; preserved but not taught as an absolute. Fixed-year reasoning replaces the unspecified this year assessment.
partial: If you ask {{name}} how many days are in September and whether this year is a leap year, can they answer both — and tell you how many seconds are in a minute?

Check understanding

State that there are 60 seconds in a minute
Name the months and state the number of days in each
Explain that a leap year has 366 days; leap years usually follow a four-year pattern, with calendar exceptions, so check a calendar for a particular year

“If you give your child a calendar, can they say how many days are in September and whether that year has 365 or 366 days, and tell you how many seconds are in a minute?”
