1 - Getting Started ~4 mins

Illustration for Getting Started Today's date is circled on our calendar. Hands up: what day of the week will it be one week from today? See if you can say it without counting every single day in between.

👇 Mark your steps as done as you complete them.

+5 XP

2 - Watch and Notice ~9 mins

Three calendar problems on the board, each already worked. Watch how the counting moves: along the rows for days, straight down for weeks. Keep your eye on where the counting lands each time.

The last one is different. Instead of counting on, we count the gap between two dates. Be ready to say how many squares apart they are.

👇 Mark your steps as done as you complete them.

Tip

We'll work these three together. Tap the start date, then use the day or week and forward or back buttons to count along the grid.

What date is 2 weeks after the 5th?
What date is 6 days after the 12th?
How many days from the 6th to the 20th?

Count on and find the gap

COPYBOOK MOMENT

Use your own printed month calendar and write the answers to these three questions in your maths copy. Point and count along the rows on your paper grid as you go.

On your printed calendar, what is the date two weeks after the 9th?

What day of the week is the last day of your printed month?
