Week 5- September 16

September 15, 2019 by Kim Sorensen & Rebecca Farley

 In math this week we will continue to find factors and multiples of numbers.  Finding factors is a tricky concept because students must have a solid understanding of divisibility rules and a determination to carefully check all numbers 2-10 before moving on.  The best way to support your child this week is to quiz them on the different divisibility rules. To practice, give your child a number such as 32 and state reasons why a number is or is not a factor.

Divisibility rules for. . .

  • 2 – if a number is even
  • 3 – if you add the digits and get a sum of 3,6, or 9. (for example, 96 has 3 as a factor because 9+6=15 and 1+5 = 6)
  • 5 – if it has a 0 or 5 in the ones place
  • 6 – if is even and also has 3 as a factor
  • 9 –  if you add the digits and get a sum of 9
  • 10 – if it has a 0 in the ones place

Another concept we are covering is prime and composite numbers.  Please ask your child what a prime number is (a number with only 2 factors, 1 and itself) and what a composite number is (a number with more than 2 factors).  Give them some numbers and see if they can figure it out. If any of the above factors work for a number than you have a composite number!

We will review factors and multiples on Wednesday and test on Thursday.  Math facts are going great so far. Our goal for 4th graders is to have multiplication facts passed off by the first 10 weeks of school.  

In 3rd grade math we are moving forward with addition and subtraction.  We will be reviewing place value strategies for addition and subtraction such as partial sums and differences and branching.  We will then connect these strategies with the traditional algorithm of adding and subtracting.  This method is definitely something us adults are much more comfortable with!  Teaching the standard algorithm in 3rd grade is new with Singapore Math and I will be interested to see how well the students do.  Please reach out to me if you have any questions or concerns.

Writing- Our narrative writing is in full swing. Students have (mostly) completed the rough draft of their seed story and are working to add a strong lead to their paper. Our class discussed what makes a strong lead and hook, and will now implement that revised portion into their paper. I will begin pulling writing groups this week. My goal is to meet with each student this week to evaluate their progress and help them through their revisions. This week your child will be challenged to add dialogue into their narrative story and understand the differences of tags at the beginning and tags at the end. 

Projects- Students enjoyed 2 exciting guest speakers last week as they shared details on the Basque settlers and Nevada Paiute and Shoshone Indians. Our new project groups have been assigned and your child will continue to research their early Nevada Settler group this coming week. Each child is responsible for completing their portion of their note taker, as well as helping their peers with research and data collection. Please make sure your child is still practicing their early NV settler vocabulary words. These words were sent home 2 weeks ago on a Quizlet print-out, and our vocabulary quiz will be in a few weeks. 

Thank you for sharing your child with me. As always, if you have any questions or concerns please email me at rfarley@oanv.org
