With Halloween just a few days away, it’s time to decorate. We’re loving this idea from the Momma Owl’s Lab blog: Take a paper towel tube, punch little holes in it with a holepuncher, then place glowsticks inside. Then take your polka-dotted decorations and stick them in windows or outside on top of your bushes. Just remember, glowsticks last only a few hours, so you’ll have to wait till Halloween itself!

*Wee ones:* How many glowsticks outside the tube can you see in the picture?

*Little kids:* If you grab 5 orange glowsticks and 4 yellow ones, how many do you have? *Bonus:* If you took those glowsticks from a pack of 50, how many are left in there to make glow-in-the-dark bracelets?

*Big kids:* If you punch 7 holes in each paper tube (all on one side so you can see them all), how many glowing spots can you get by filling 8 tubes with glowsticks? (Hint if needed: Multiplying by 8 is like doubling a number 3 times in a row.) *Bonus:* If a real spider is normally just 1/2 inch wide and the big decoration ones are 26 times as wide, how wide is the fake spider?

Answers:

*Wee ones:* 4 glowsticks.

*Little kids:* 9 glowsticks. *Bonus:* 41 glowsticks.

*Big kids:* 56 spots. *Bonus:* 13 inches.

And thank you to blogger Rachel Ford for this great idea!
