Dear Parents,
As you know, I am G-d willing getting married this coming week. We've put a subbing arrangement in place so that learning should continue as smoothly and productively as possible until I return: Math each day will be taught by Mr. Goodman, and all other subjects will be taught by Morah Rivky Balser. Fridays will be covered by Morah Mushkie Polter who will do fun activities with the class. I've prepared homework logs for both weeks, so homework should continue as usual without any changes. If you have any questions, please email me; I will do my best to respond.
I look forward to seeing you all in a few weeks.
All the best,
Morah Nechama Dena

The Best Star Party (and Chanukah Party) Ever!
We earned a fantastic, fun Star Party! We earn lines on each star (we need a total of ten) for cooperation, respect for each other and teachers, and focused learning. We began with an awesome Chanukah acrostics/writing activity. We each came up with creative, Chanukah-themed poems. We then went on a high-energy scavenger hunt (the best part, for sure) to find the secret bag with the rest of the day's activities: Chanukah 'gelt' chess games, and a frame decorating craft. We saved the delicious caramel doughnuts for the next day, because we thought we'd spread out the fun...Yum! We also wrote creative pieces on Chanukah; Morah was amazed at the creative ideas the students came up with!

Math Update
We've been moving along Unit 5, discussing ESTIMATION of large numbers, MULTIPLICATION of extended facts, and working with decimals.
ESTIMATION: We've learned that it is often helpful to estimate an answer to a problem rather than solve it exactly when the exact number is not what we are looking for. For example, if we are taking a road trip and we want to know how many days it will take us to get to our destination (if we travel a specified number of hours per day), it is most helpful to get an estimated numbers due to variables of weather, traffic, construction, etc. We pretended we were taking a road rtrip and estimated the number of miles we'd travel and how long it would take us to reach our destination if we traveled 8 hours a day. Next time you need help planning a road trip, just ask us!
We also have been practicing "magnitude estimation" where we are given averages and need to use the data to come up with further calculations. For example, we read that the average life span for an American is 77 years. We also know from a 2002 survey from the Department of Agriculture that an average American eats 30 pounds of cheese a year. In that case, we needed to figure out: how many pounds of cheese would an average American eat in their lifetime? (about 2,310 pounds of cheese!) (We discussed the meaning of "average" and know that many Americans would eat more, many would eat less. This number reflects all the data put together, divided by the population. We also discussed how our personal outcomes were either same as or different than the average American.)
MULTIPLICATION OF EXTENDED FACTS: We've been practicing extended facts which is helpful in estimating large numbers! For example, knowing 3*4=12 is helpful in solving 3*40=120 as well as 30*40=1200. Say an average American drinks 28 cups of water a week, and we want to know how many cups in a month, we can ESTIMATE: 30 cups * 4 weeks = about 120 cups per month.
We've continued working with deciamls: adding a nd subtracting and lining the numbers up properly.
I highly recommend discussing these concepts at home when useful! It will reinforce the lessons.
