With Halloween coming soon, have you thought about wearing more than one costume? You might if you could change from one into the other really fast. The magicians in this wacky video broke the world record for the most costume changes in 1 minute. Avery Chin holds a tall black cloth tube with Sylvia Lim standing inside it. Every time Avery lifts the tube up and back down, Sylvia has switched into a whole new outfit! She made 18 costume changes, breaking the previous record of 16. Can you figure out how they did it? We still can’t!
Wee ones: If you wear 6 different costumes for Halloween, what numbers do you say to count them?
Little kids: If you have 2 pairs of pants and 2 shirts, how many different outfits can you put together? Bonus: If Sylvia started in 1 costume and then changed into 18 more, how many total costumes does she wear in the video?
Big kids: If Sylvia had worn a red dress on every 4th change, how many of the 19 costumes at most could have been red dresses? Bonus: Avery and Sylvia spend the last 6 seconds of the minute taking bows. If they used the rest of that minute on 18 changes, how many seconds did Sylvia take for each if they all took equal time?
Wee ones: 1, 2, 3, 4, 5, 6.
Little kids: 4 outfits, since each pair of pants can go with each of the 2 shirts. Bonus: 19 costumes.
Big kids: 5 costumes. Bonus: 3 seconds each, since that comes to 54 seconds.
