Ninja were secret warriors hundreds of years ago who could leap, run and climb super-fast and super-quietly. Well, one girl wanted to practice being a ninja, so her very cool dad built a training course in their backyard. She has to jump through a set of slanted boards, balance on wobbly, seesawing beams, and dash over the roofs of not one but two sheds. If you could do it, you might be a ninja, too!
Lace up: If you leap onto a slanted step facing left, then another facing right, then another facing left, then facing right…which way does the next one face?
Jog: If you’re 10 seconds from finishing the ninja course, what numbers do you say to count down?
Sprint: If there were 9 slanted steps for her to zigzag through, starting facing left, then right, then left and so on, how many slants would face each way?
Hurdle: If the whole ninja course takes 2 1/2 minutes, how many seconds does it show on the stopwatch when she’s done?
High Jump: If a full run took 150 seconds and the sheds took 1/3 of that time, how many seconds would they take? (Hint if needed: What if they took just 1/3 of 15 seconds?)
Answers:
Lace up: It faces left.
Jog: 10, 9, 8, 7, 6, 5, 4, 3 ,2, 1.
Sprint: 5 would face left, and 4 would face right.
Hurdle: 150 seconds.
High Jump: 50 seconds.
