Spotted on Halloween

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!
