Bed is a quiet place to sleep – but this one is more like a treehouse, ball ramp and jungle gym combined. Eric Strong’s son didn’t want to move from his toddler crib into a big-boy bed, so Eric built the most awesome kid bed ever. Eric started with a loft bed, then added 3 cubbies and a slide onto the end. The bookcase swings open to a secret compartment, and a ball ramp drops golf balls into a bucket, which the kid can haul back up to the top using a rope. It’s awesome, but we wonder if he ever sleeps!

*Wee ones:* If the boy was 3 years old when the project started but has had a birthday since then, how old is he now?

*Little kids:* The ball ramp tilts and dumps out the balls when all 6 have landed in there. If right now it’s holding 4, how many more balls are needed to tilt it? *Bonus:* If instead there’s an odd number of balls in there, what numbers could that be, if there are 6 at most?

*Big kids:* If the dad put together 20 pieces to make the bed, 4 for the slide, and 15 for the secret compartment door, how many more pieces would have brought the total to 40? *Bonus:* If the boy can climb up and slide down the slide in just 20 seconds, how many times can he slide before bedtime 3 minutes from now? (Reminder: A minute has 60 seconds.)

Answers:

*Wee ones:* 4 years old.

*Little kids:* 2 more balls. *Bonus:* 1, 3 or 5 balls.

*Big kids:* 1 more piece, since there were 39. *Bonus:* 9 times, since he can fit in 3 rides per minute.
