Let's go fly a kite, up to the highest height
Let's go fly a kite and send it s –o- a- r- i- n- g !

 
We had the most fun over the recent school holidays. Uncle Bill showed the kids how to make their own kites. Each used a special paper so we could tell the kites apart while they were in the sky.
 

"How can we tell how high they will fly?" asked Barney as he added the last ribbon to his tail.

"Well, I always marked off my kite string every meter," explained Uncle Bill. "That way, when I brought my kite in, or it fell to the ground, I could tell how high it had flown."
 

The kids thought that was a good idea and, although it took a bit of time, each child used a marker and a meter stick to make a mark on their balls of kite string every meter, as they wound it around a stick. Then it was off to the athletic field near our house to give the kites a try.
 

When they returned they were so excited. All three kites had gotten off the ground and none had broken free or gotten tangled in a tree.

"How high did they fly?" I asked.
 

"We were hoping you would ask that!" laughed Barney. "And we are prepared with a little challenge for you."

"Can I tell it?" begged Gina.

"OK" agreed her cousins.

"My kite went 10 meters higher than Barney's. Barney's went 10 meters higher than Danny's."
 

"And when we measured," interrupted Danny, "Together they flew 120 meters off the ground! Now you have to figure out how high each of our kites flew, aunty."

"Wow! I don't guess you'd settle for the answer 'really high' would you?" I said, laughing.
 

Well, it's a 'tall' order but I'll bet you can figure this challenge out if you try. When you think you know the answer, please post your solution on the message board.

I will be waiting to hear from you and I will answer you if you tell me your strategy as well as your solution. Include your e-mail nickname or first name only, your teacher's name and school, and your grade. Then check back in a few days for a personal message from me.

Love, Aunt Mathilda

P.S. Have you ever flown a kite? How high do you think it flew?


 

Aunty Math regrets she cannot respond to solutions to these Past Challenges but thanks for giving them a try.

I'd like to try the wee bit easier challenge, please.

I'd like to try the wee bit harder challenge, please.

I'm a parent/teacher and want to review parent/teacher tips for this challenge!
