Today’s date, my peeps, is a #FactFamily date
5 + 21 =26
Or if you prefer
21 + 5 =26
Questions:
1. Does every month have such a date?
2. What’s the last year when this wasn’t true? What the next time this won’t be true?

Today's date - 11/11 - is a binary number (base 2)
It's the largest binary number in the calendar

In the most impractical date representation - mm/dd/yy, today's date - 4/2/24 - is a palindrome 😃

I almost forgot!
Today's a fact family day!
1 + 23 = 24
And for the non-US folks
23 + 1 = 24

Other "two square" dates:
Jan 1, 4, 9, 16, 25
Apr 1, 4, 9, 16, 25
Sep 1, 4, 9, 16, 25
The last square year was 1936 (44*44)
The next one: 2025 (45*45)
#ItsHipToBeSquare #CalendarMath #MathIsAllAroundUs
Today's date 9/16 (or 16/9 for the rest of the world) has two squares - 9 and 16.
▫️⏹️
Previous "two square" date was - Sep 4th
Next two "square date" is in 9 days - Sep 25th
And that's the last double square date of the year

We LOVE comparing/contrasting Louisville’s weather in our morning meetings. ☀️☁️☔️ @McFerranKY @LDJones01 #room111 #weatherjournal #calendarmath #wishingforrainbows
Today's date in the US format - 12/15/21 - is an interesting mathematical progression of multiples of 3.
12/15/21 --> dd+3 = mm and mm+6 = yy
#FactFamily #CalendarMath
Too cool! 💯
Love that the first nine dates of this month this year is a consecutive sequence of palindromes:
12.1.21
12.2.21
12.3.21
12.4.21
12.5.21
12.6.21
12.7.21
12.8.21
12.9.21
When was the last time this happened? When will be the next?

619 days later at the school campus :) It's always an enriching experience to be working from a happy classroom❤️

#calendarmath @ois_primary @twisha_b @nehaminda @chchkiwiT @PYP_Teacher Hopeful to see kids back at the campus!
Calendar math got a little exciting this week thanks to the complement party the class has earned. Learning about whole, halves, and fourths this month! #countryhillselementary #mathrocks #calendarmath
Today’s date is a perfect 10 😀
1010 - in binary (base 2) is 10 decimal
(2^3 + 2^1)
And of course, it’s 10/10 (in both mm/dd and dd/mm formats)
Like I said, a pefect 🔟
