After gym and music, we watched the following video.
Our job was to figure out how many packages of buns and how many packages of hot dogs George could buy so that he had no extra hot dogs or hot dog buns.
Then we found out how many packages could be bought if there were 5 hot dogs in a package and 8 buns in a package? How many packages could be bought if there were 7 hot dogs in a package and 12 buns in a package? How many packages could be bought if there were 6 hot dogs in a package and 16 buns in a package?
We discovered that to find how many packages of each item could be bought, we needed to find common multiples for the two numbers.
For example to find the answer to the original problem:
Hot dogs- 8, 16, 24, 32, 40, 48 ...
Hot dog buns- 12, 24, 36, 48 ...
24 and 48 are common multiples of 8 and 12. So, George could buy 3 packages of hot dogs and 2 packages of buns. He could also buy 6 packages of hot dogs and 4 packages of buns. There would be other answers as the multiples of each number are infinite. The least common multiple (LCM) of 8 and 12 would be 24.
In Science, we were presented with a Survivor Moon Challenge:
"Countries from around the world are getting ready to send humans farther into our solar system, beyond the International Space Station. Nearly 400 000 km away from our planet, the Moon represents a crucial stepping stone in humanity's quest to travel onwards to Mars. Because the Moon is so far away, astronaut crews will have to act with more independence and autonomy than ever before.
Each team represents a crew of astronauts who were forced to make an emergency landing 50 km away from their lunar base. The crew is safe but must survive the trek to the base. They can only carry a few supplies with them on their journey. The most critical items must be chosen from a list of 15 items that could help the crew survive until they reach the lunar base. Each team must analyze and then rank the items in order of importance for allowing them to safely get to the base. Each team must also write the survival benefit of each item."
It was great to see students using their background knowledge of the moon and teamwork in their groups as they ranked the items from most to least important.
We also finished our "Reasons for the Seasons" creative journal page.
