### Modeling Adding and Subtracting Decimals

October30

Hi Parents! We have been working on modeling addition and subtraction of decimals. Below you will find a video illustrating how to complete this required standard. We have given each student a study guide as we will be testing their knowledge in this area on Thursday. Should you have any questions, please send me an email and I will be more than happy to assist you.

### Science: Physical and Chemical Changes

October15

Hi Parents!

Over the next two weeks, we will study physical and chemical changes. We have some exciting labs planned for our students as we explore the difference between physical and chemical changes. In addition to the video, below you will find information that will assist your child in understanding what constitutes a physical change and what constitutes a chemical change. Should your child have any questions, please have them see myself and/or Ms. Raque.

A physical change in a substance doesn’t change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

For example, if a piece of paper is cut up into small pieces it still is paper. This would be a physical change in the shape and size of the paper. If the same piece of paper is burned, it is broken up into different substances that are not paper.

Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all. For example, a cup of water can be frozen when cooled and then can be returned to a liquid form when heated.

If one decided to mix sugar into water to make sugar water, this would be a physical change as the water could be left out to evaporate and the sugar crystals would remain. However, if one made a recipe for a cake with flour, water, sugar and other ingredients and baked them together, it would take extraordinary means to separate the various ingredients out to their original form.

When heat is given off in a chemical change or reaction, it is called an exothermic reaction. When heat is absorbed in a chemical change or reaction, it is called an endothermic reaction. The speed at which chemical reactions take place depend on the temperature pressure and how concentrated the substances involved in the chemical reaction are. Sometimes substances called catalysts are used to speed up or help along a chemical reaction. Light is helpful in the processing of film.

### Let’s have 100% Mastery!

September17

Parents,

Please have your child practice his or her multiplication facts until mastery. While many students are making progress, we have a few who are making mistakes on assignments as they have yet to fully memorize their facts.

As a class, we have reviewed strategies previously learned in 4th grade, such as the area model and partial product, as well as our continued practice finding the product using standard algorithm. All students had the opportunity to create a “Progression of Multiplication” booklet to assist in understanding how repeated addition, the area model, partial product, and standard algorithm are related. Below you will find a video that will assist in understanding how to multiply 2 -digit by 2-digit numbers.

Please let me know if you have any questions and/or concerns.

### Lunch with students

May11

Parents,

We welcome you to come and enjoy lunch with your student on the stage! However, when joining your student for lunch, only your student is permitted to eat with you on the stage.  Lately, there has been an issue with multiple students dining with one adult taking up the limited seating and generating lots of traffic in the stage area with students moving between their classroom seating and the stage area.

Thank you for your cooperation in making sure we provide ample space for guest diners and in reducing the amount of traffic at the stage area.
