July Calendar Counts
Part of: Calendars, clocks and age
July 2024 opens on a Monday with Sundays on 7, 14, 21 and 28 and Thursdays on 4, 11, 18 and 25. Counting ahead works too: 3 days past the 22nd is Thursday the 25th.
Why it matters. Date jumps plan holidays and reopenings. Reading weekday rows is calendar fluency.
Try it in two minutes
- Open any month and circle all Sundays.
- Count 3 days ahead from the 22nd.
- Add 15 days to the 7th and name the date.
Try at home. Count the Sundays in the current month together.
Years, Weeks and Ages
Part of: Calendars, clocks and age
A year packs 365 days and 52 weeks. Ages count birthdays: born 2 May 2015 turns 10 on 2 May 2025, and twice-plus-10 solves Hetal as 20 with her brother 10.
Why it matters. Year counts frame every plan. Age puzzles turn clues into equations without symbols.
Try it in two minutes
- Count 52 weeks on a year calendar.
- Work out age from a birth date.
- Solve: twice me and 10 more means start at 10.
Try at home. Work out how old a family member will be in 2030.
Reading the Clock
Part of: Calendars, clocks and age
Clock hands split the hour: 15 minutes past is quarter past, 30 is half past. Breakfast from 7:00 to 7:15 runs 15 minutes.
Why it matters. Clock reading runs daily routines. Quarters and halves are the first fractions of time.
Try it in two minutes
- Point the minute hand at 3: quarter past.
- Point it at 6: half past.
- Time breakfast from start to finish.
Try at home. Time brushing teeth with a clock and count the minutes.
What Takes How Long
Part of: Calendars, clocks and age
Jobs wear fitting clocks: showers take minutes, shirts take hours, radish takes weeks and sweaters take months. Digital clocks show digits; analog clocks use hands.
Why it matters. Right-size clocks plan work well. Sorting by duration is time sense in action.
Try it in two minutes
- Sort four jobs into minute, hour, week and month piles.
- Spot a digital clock and an analog clock at home.
- Ask: sweater in minutes or months?
Try at home. Sort brushing, cooking, exams and seasons by time taken.
