Growing Like a Weed
Have you ever noticed that your hair and fingernails seem to grow when you aren't even looking? It’s true! Your body is like a little factory that never stops building. Hair on your head grows about 1 centimetre every month, and your fingernails grow a tiny bit every single day. Let's use our math skills to see just how much growing you're doing!
Wee Ones
If you have 5 long fingernails on one hand and you clip 2 of them, how many long fingernails are left?
Little Kids
Your fingernails grow about 3 millimetres every month. If you wait for 2 months, how many millimetres will they have grown in total?
Big Kids
Hair grows about 12 centimetres in one year. If you want to grow your hair 60 centimetres longer to reach your waist, how many years will it take?
The Sky's the Limit
Fingernails grow at a rate of about 0.1 millimetres per day. If a fingernail is exactly 1 centimetre long today, how many days will it take for it to grow to a length of 1.5 centimetres?
