6174 is known as Kaprekar’s constant, discovered by the Indian mathematician D. R. Kaprekar. Take any 4-digit number, using at least two different digits. (Repdigits like 1111 won’t work, as they lead to 0.) Arrange the digits: In ascending order (smallest to largest) Then in descending order (largest to smallest) (Add leading zeros if needed—for example, 4560 → 0456 and 6540) Subtract the smaller number from the larger number. Repeat the process with the result. This process, called the Kaprekar routine, will always reach the number 6174 within at most 7 iterations. Once you reach 6174, the process becomes constant: 7641 − 1467 = 6174 And it will keep repeating forever. Example: Take the number 4906: 9640 − 0469 = 9171 9711 − 1179 = 8532 8532 − 2358 = 6174 7641 − 1467 = 6174.

what if there was one chicken, with the same mass as all the world's chickens combined? it would be about 1.2km tall. what about one ant from all ant species? one cow? one human?

See it once, and you never forget it. 📽️ H. Joachim Schlichting

❌ Phrases like "addition creates a larger number" can lead to misconceptions as students explore decimals, fractions, and negative numbers! ✅ Make the math visual for your students! 👀

🔵 "Making a ten to subtract" is a powerful strategy to help students visualize subtraction facts! 🟢

@LipoMigena Our favourites are the moon-shaped cookies. 🌛 Well done, mathematicians 🙌 #dpmath

Guess #howmany cookies RAISE Ss @GoetzGators organized/sorted by attributes like colours, shapes & types? Which one is your favourite? @Dp_math #mathplay ⁦@GlobalMathDept⁩ #mathplay4all #mathisfun

@StPeterDPCDSB CONGRATULATIONS mathematicians! 👏 #dpmath

🎉 Congrats to our amazing students for completing the Knowledgehook Mathalons! Their hard work, problem‑solving, and determination truly shined. We’re so proud of their medals, banners, and all the learning they achieved along the way. @knowledgehook @DP_math @DPCDSBSchools

#MarchBreak is here! 🎉 Enjoy your well-deserved pause #dpmath friends! #onted

"Financial Fun Friday" in full swing during a visit this morning to see @s_chisholme at St. Jean Brébeuf. So great to see Grs. 2&3 students in Mrs. Watson's class using concrete materials & @brainingcamp to help them solve a @DP_math Problem of the Week. 🙌 #dpmath

Love spotting student art posted in school hallways. These 👇🏼 beauties @DpAssisi could become #HowMany conversations. #TheArtsMatter #dpmath

Pope Leo XIV, who taught mathematics and physics, sends a message on the occasion of the International Day of Mathematics, reiterating that having a great deal of knowledge is not enough if we do not know who we are or what the meaning of life is. vaticannews.va/en/pope/news/2…
