December News and Classroom Updates

Bringing IXL home! FREE ONLINE LEARNING FOR YOUR CHILD to support and encourage your child! We’re happy to announce that we will use IXL to help reinforce our classroom curriculum this year. IXL is an online learning site that provides unlimited practice in over 6,000 topics. We’ve created a personal account for your child—sign in and explore! Getting started with IXL IXL is an online practice program that we will use to reinforce the curriculum this school year. The program will allow us to individualize the learning experience for students so that they can work at their own pace to master the material we will cover. Your child can sign in from home by visiting www.IXL.com on any computer and entering the username and password provided by the school. There are even iPad and Android apps to allow your child to practice on the go! Making the most of IXL To reinforce what your child has learned at school, have him or her practice on IXL at home! Your child has unlimited access to all IXL grade levels, and he or she can practice anywhere with Internet access. IXL breaks down topics into progressive skills for each grade level and content area, and provides immediate feedback with question-specific explanations for every incorrect answer. This makes it easy for your child to practice the material he or she needs to fill gaps in learning, keep up with the class, and even advance in topic areas of interest. Monitoring progress We want you to be involved in your child’s education this year, and IXL will help keep you connected. When signed in to your child’s account, a number of progress reports will be available to you under the Analytics tab, including the following that we recommend: Progress and improvement: View all of the skills your child has practiced, and the progress he or she has made throughout the school year. Trouble spots: View just the question types that your child is struggling with so that you can provide targeted help at home. The IXL SmartScore When tracking your child’s progress, you will notice that many of the reports display a SmartScore for each skill. This is not a percentage or standard scoring system, but is based on a unique algorithm that understands the learning process. The SmartScore takes into account not only the number of questions a student has answered correctly and incorrectly, but also the difficulty of the problems and the student’s ability to answer correctly with consistency. The benefit of this system is that the score will adapt no matter how many questions your child answers, ensuring that every student always has the possibility of reaching his or her SmartScore goal.

- 7th graders are working on how to read long, complicated expressions and equations. We are able to apply the order of operations and simplify and/or solve the equation. We also practiced some circle math, finding the radius, diameter, and calculating the area and circumference of whole and partial circles. We will have an assessment on these skills this week.

- 8th graders are studying growing patterns and how to represent them in four different ways. We are using tile patterns, tables, graphs, and rules (equations) to define how a pattern grows. We want to be fluent, moving from one representation to another, and be able to (for example) accurately predict the size and shape of the 97th figure in a series of growing patterns. We will be finishing this unit with test on Wednesday.

- Both grades are concluding their study of Human Body Systems. We have had great success with key terms and concept online assessments. Next, we are working to improve our written responses, how to make our writing stronger with better organization and the addition of specific details and examples. Soon, we will be introducing physics of motion (Newton’s Laws) and electromagnetism.

Dear Parents:

A case of head lice has been found in your child's class. Cases of Pediculosis (head lice) among school children are common. Therefore, we are asking the help of parents in controlling and preventing the spread of this condition.

Head lice are wingless insects that live only on humans. They make their home on the hair and scalp of their hosts, especially at the nape of the neck and behind the ears where it is warm and dark. It is in the hair that the female head louse can lay from 50 to 150 nits (eggs), which hatch within 5 to 10 days. The life cycle of the louse is about 30 days.

One can detect the presence of head lice by noticing frequent itching on the head, and finding the nits in the hair.

The egg or nit is oval in shape and resembles dandruff in appearance. Unlike dandruff it won't flake off the hair. The nits are attached to the hair strand by a glue-like substance, which makes it difficult to remove them.

The lice themselves, while visible to the eye, are less often seen. An adult louse is about 1/16 to 1/8 of an inch in length and varies in color from a grayish white to a grayish black.

Cooperation of parents and careful observations by school staff can soon bring conditions under control and eliminate this nuisance in the schools.

1. Examine your children carefully for any signs of lice and nits.

2. Report any symptoms to the school nurse, principal, or teacher in order that school contacts may be inspected and treatment explained.

3. School health policy states that children with lice or nits be excluded from school, and should be nit-free before re-entry. School personnel prior to re admission will carry out inspections.

RECOMMENDATIONS FOR TREATMENT OF HEAD LICE IF YOU OR YOUR CHILD HAVE HEAD LICE…

Check other household members: lice often spread to all members of the family.

Contact your physician, school nurse, or pharmacist. He/she can recommend a product to get rid of the lice. Be sure to FOLLOW the INSTRUCTIONS ON the LABEL. Home remedies are rarely effective enough to kill all the lice.

TAKE THESE STEPS AFTER USING THE RECOMMENDED PRODUCT . . . .

ØØ Comb the hair with a fine-tooth "lice" comb to remove the lice and their eggs (nits) (The combs that have the longer metal tines with grooves in them work the best). Then pull off any remaining nits and destroy. Comb every morning and evening for at least a month.

ØØ Thoroughly clean brushes, combs, washable hats, headbands, and hair ornaments with hot, soapy water

ØØ Wash clothing, bedding and towels in hot, soapy water (130˚ to 140˚ F) and placed in the dryer on the hottest cycle for 2 cycles

ØØ Stuffed toys or articles of bedding , which cannot be laundered, should be placed in a large plastic bag and closed shut and left for at least 2 weeks.

ØØ Thoroughly vacuum mattresses, floors and furniture, car seats and upholstery

ØØ Inspect all family members weekly after treatment for lice. Do this for about one month, and then periodically check family members. Recheck and retreat in 2 weeks (even if you don't see any more evidence of lice)

TO PREVENT GETTING THEM…

ØØ Wash hair frequently and thoroughly with regular shampoo.

ØØ Articles such as combs, brushes, hats, headbands and hair ornaments transfer lice easily - DO NOT borrow or share these items.

If your hair is long, wear it up in a bun or a braid.

Dear Middle School Families,

Welcome!

It's been a real pleasure meeting my new seventh graders and welcoming new and returning eighth graders this past week. I'm looking forward to Back to School Night (September 7) and the chance to meet the seventh grade parents.

This past week, we have begun our study of Human Body Systems. We have been discussing the idea that math is the study of patterns, and that there are many ways to represent patterns. We had our first Advisory meeting and have broken out into rotations for Enrichment. The seventh graders seem to be getting used to moving to a different teacher and classroom several times a day.

If you wish to speak with me, please stop by the Red Alder classroom after school or email me at ddemarche@harmonyusd.org.

All the best,

David DeMarche
