  • We have a new calendar of important events for the school year, including new dates for field trips. This includes canceling the scheduled Community Lunch for this Thursday, Oct. 28. Please let us know if you are interested in helping organize a Community Lunch in the future.
  • Math Club debuts at lunch/recess this Thursday. Ask your student if they plan to attend!
Homework:
  • Spelling: For homework, the students will practice the words on their personal list, and complete the vocabulary word definition assignment. Due Thursday.
  • 4th grade math: Cut out and bring in 2 examples of graphs from newspapers, magazines, or web sites. Give your parents their letter about this unit, which you can download here.
    Due tomorrow, Wednesday.
  • 5th grade math: The problem of the week is due Friday, and students should work on it for homework this week.
Math:
Today fourth and fifth graders worked together cooperatively in groups of 3 or 4 students to solve five different three-dimensional problems called "Build It!" Each student had one or two clues they shared with the others, and after much perseverance with the connecting cubes, they shared their solutions with the class. It was a great opportunity to learn more about working in collaboration, taking turns, and learning from each other.

Science:
We have been discussing ecosytems and how there can be mutual relationships in science. Today we asked whether wolves can help rabbits, by running a computer simulation of wolves, rabbits, and grass, that you can check out here:

Shodor Rabbits & Wolves

Students worked in pairs on the computer with a See, Think, and Wonder thinking routine to figure out what was happening to the grass, rabbits, and wolves. They altered the number of rabbits or other parameters to see whether they could create a balanced ecosystem. Sophie made a great observation that although an individual rabbit may not be helped when killed by a wolf, the population of all the rabbits can be helped when a wolf kills some rabbits, since the rabbits won't overpopulate and starve. It was great to see the lightbulbs going off!

Social Skills program information from Kate Klaire:
Hey Parents! We would like to invite you to join us in supporting your kids with our new Social Rules Books (or curriculum). We will let you know each week or two what rule(s) we are working on and you can join the fun of working on these rules with your kids at home. This week we have been working on what it means to be both a speaker and a listener. We talked about some important aspects - eye contact - taking turns - sharing the space - be a part of the group. Ask your kid to try it with you.
