Have you ever seen a real baby bunny, just a day or two old? They don’t look anything like what you’d expect. Photographer Arefin Ashraful’s pet rabbit, Tooni, had 4 baby bunnies, called “kittens” just like baby cats. Arefin took amazing pictures of them right from day 1 to show how baby bunnies grow. They don’t have any fur for the first 7 days, and their eyes don’t open until day 10! (That’s one of the cutest pictures, shown here). As you can see from Arefin’s hand, the kittens are only a couple of inches long at birth. But they grow really fast: by 10 months they’re full-size like their parents. We humans take a good 14-18 years to do that!
Wee ones: Find 4 things small enough to fit in your hand like this baby bunny.
Little kids: If Tooni had 4 baby bunnies, how many bunnies did Arefin then have all together? Bonus: If the bunnies open their eyes on day 10, how many days do they spend with them closed?
Big kids: If the bunnies were born on a Tuesday, on what day of the week would their eyes open if it’s their 10th day of life? Bonus: If Tooni’s 4 kittens have 7 kittens each, and another bunny Toby’s 5 kittens have 5 kittens each, which bunny has more “grandkittens”?
Wee ones: Items might include bouncy balls, marbles, Lego pieces, a bar of soap, or keys.
Little kids: 5 bunnies. Bonus: 9 days.
Big kids: On Thursday of the next week…their 10th day of life is 9 days later. Bonus: Tooni. She has 4 x 7 = 28 grandkittens, while Toby has 5 x 5 = just 25 grandkittens.
And thank you Arefin for sharing your incredible photos with us!
