Progress Report

Dear Families,

Today, your child brought home their first progress report of the year.  Please take some time to review it with your child and reflect on his/her successes and possible areas for improvement as we head into our 6^th week of 4^th grade. 

Progress reports will be coming home on Mondays and will typically reflect a week’s worth of grading and homework completion.  This week’s report is much longer than normal because it covers the first several weeks of school.  Grades are reported in order, with the newest grade at the top of the list.  Some past scores may have already improved within the time-frame of this progress report.

Above all, this progress report is meant to be a tool for reflection, goal setting, and planned improvement.  These grades are not final and students receiving scores below standard are receiving targeted instruction in class and further assessment to mark their growth. 

After reviewing and reflecting, please sign the coversheet attached to this packet and have your child return it to school on Tuesday (10/8).

As always, if you have any questions or immediate concerns, do not hesitate to contact me by phone or email.

Have a wonderful week!

Learning Target for October 2nd

Factor, Multiple, Prime Number, Composite Number

October 2nd

Information learned in class that might be helpful at home:

Factor- a whole number that divides a whole number without a remainder
            (or) One of the two whole numbers that multiply together to get a product.

Multiple: The product of the same factor multiplied by continuing numbers
                (or) It is skip counting.

Examples:

Factors of 24- 1,2,3,4,6,8,12,24
Multiples of 24- 24,48,72,96,120...

Prime Number- has only 2 factors, 1 and itself.

Composite Number- has 3 or more factors.

Examples:

Prime Numbers: 1,2,3,5,7,11,13,17,19,23
Composite Numbers: 2,4,9,12,99,100,625 (any number that is not a prime number)

Common Core Standard 4.OA.4:

Find all factor pairs for a whole number in the range 1–100. Recognize

whether a given whole number in the range 1–100 is a multiple of a

given one-digit number. Determine whether a given whole number in

the range 1–100 is prime or composite.

Rounding Rules

Common Core Standard 4.NBT.3: Use place value understanding to round multi-digit whole numbers to any place.

Hello Room 21 Families!

This blog is for Room 21 parents and students! Many of the families that came to curriculum night suggested that I start a blog to help parents/students struggling with math homework. Information that you will eventually find on this blog will include:

• any math strategies we are practicing in class
• step-by-step instructions on the process that we go through as a class to solve problems in our current unit
• website resources that might be useful for your child

FYI- many of the strategies that I will post will simply be pictures of the reference charts that the students and I created together in class. These will be very familiar to students and also very helpful if students hit a difficult spot in their homework.

I will also post the answer to each week's Problem of the Week on Friday. That way families who are working on it together can check their thinking!

Thank you for being patient as I get everything set up but I hope that this is a helpful tool for the families and students of Room 21.

Miss Sharpe
