We are coming to the end of the fractions, decimals, and percents unit, but that doesn’t mean it’s the end of learning.  The best way to master a concept is to continue practicing!  You can use the links from the previous blog post, or try this new one:

Math Playground – Computation

Our upcoming unit is Change.  Below is a brief overview of what we’ll be covering during the final quarter in math and science.

Math—Algebra Concepts and Skills, Fractions-Decimals-Percents

In this unit your child will be introduced to pre-algebra concepts and skills.  They will concentrate on solving problems using a balance-scale model, which means making sure that a change to one side must be compensated with a change to the other side. Students will also represent relationships as algebraic expressions.

In the next part of the unit students will investigate the relationships among fractions, decimals, and percents.  They will learn strategies to change numbers from one form to another in order to solve problems.

As always, we strongly encourage your child to continually practice their basic facts: multiplication, division, addition, subtraction, and estimation skills.  The ISM Portal has several links to games that can help reinforce these skills. Your child knows how to access them!

Science—Variables and Light and Sound Energy

Over the course of the year we have spent a lot of time designing and carrying out investigations using the scientific method.  We’ve talked a lot about making our investigations a “fair test” in the past three quarters.  However, in this unit we will introduce how to do that in a more scientific fashion by controlling and manipulating variables through investigations involving sound and light.  We will also be focusing on the transdisciplinary skill of critical thinking and problem solving as students become more self-directed in designing their own investigations.  Below is a brief summary of some of the science concepts we will be learning about:

• Variables:
  • Independent Variable—the one thing you change in an investigation
  • Controlled Variable—all the other things you keep the same in an investigation
  • Dependent Variable—the outcome of your investigation (usually this is what you measure)
• Energy:
  • Sound and light are forms of energy that travel in waves
• Light:
  • Light is a form of energy that travels in transverse waves in a straight line
  • Color is the light that bounces back
  • We don’t see things, we see light bouncing off of things; light can bend, bounce, absorb or go through objects
  • When light slows down it changes direction; this causes it to be reflected or refracted
  • Reflection—light bouncing back: straight on and straight off
  • Refraction—light that is curved or bent  (changes course slightly )
• Sound:
  • Amplitude—height of wave; louder or quieter; measured in decibels (dB)
  • Loudness—how “loud” individuals perceive sound to be
  • Pitch—highness or lowness of a sound based on frequency
  • The higher the frequency, the higher the pitch

Pi Day is every March 14th.  Get it? 3.14???

To participate in the class reciting contest:

        1.Get a slip of the first 100 places of pi from Ms. Navar.

        2.Spend every free moment from today until 3/14 memorizing as much of pi as you can.

        3.Be ready to recite in front of the class (you get a second chance if you mess up the first time).

You can also bring pie to share as a treat after the contest!

(Please Please Please: bring plates and utensils if you bring pie.)

On Thursday February 16th 2012, we will be holding our annual “WORMPOSIUM 2012”.

Just like real scientists, we will be sharing the results from our investigations and you invited to participate.

Thursday, February 16th 2012
Morning Sessions: 8:00am-9:00am

(Homebases presenting: Cooling, Navar, Powell, MacLachlan)

Afternoon Sessions: 11:00am-12:00pm

(Homebases presenting: Henshelwood, Elwell, Bird, Cook)

Sessions will be conducted in the science classrooms listed below.  Outside each room, a
schedule will be posted with the title of the presentation and the names of our
wonderful presenters.

Mrs.Cooling’s room (P024), Ms. Navar’s room (P029),

Ms. Powell’s room (P030) and Mr. MacLachlan’s room (P027).

Hope you can make it!

Here is another website that has a collection of MATH GAMES.  Games are organized by grade level, so you can find one that is just right for you or one that will give you a bit of a challenge.

This week in Science, students used keys to identify the rocks we’ve been studying this quarter.  Students matched the rock to the correct name by observing properties such as color, crystal size, grain size, and foliation.  I was so impressed by how well everyone did!

Okay Rock Stars, what are these?

**First person to correctly identify the three rocks below gets a very special pencil!!

Patterns are all around us, so take a moment to look around and find them.  In our second unit we will think about the following questions:

*How can patterns help us understand order in the world?

*What inferences and predictions can we make about patterns?

These are the topics that we’ll investigate in Math:

• Order of operations
• Computations: addition, subtraction, multiplication and division
• Collecting and analyzing data
• Represent data using a tally, list or chart
• Create and interpret different types of graphs
• Use maximum, minimum and measures of central tendencies (mode, median, mean and range)
• Draw conclusions, compare data and make predictions
• Probability

These are the topics that we’ll investigate in Science:

• Identifying Crystals and Minerals
• Types of rocks
• Rock cycle
• Using keys to classify and identify
• Weathering
• Erosion
• Deposition

Below is an overview of what we will learn and practice in the first quarter.  Be on the lookout for links to websites and resources that can be accessed for home practice.  These links will be at the top of the blog page under “Math”  and “Science”.

In SCIENCE this quarter, students will be designing and conducting investigations using the Scientific Method. The following skills will continue to develop throughout the year:

• Writing Aims and Hypotheses
• Drawing and labeling diagrams using leaders and labels
• Writing a detailed procedure
• Collecting and data organizing
• Creating graphs (bar, line and line plot)
• Analyzing and interpreting data
• Writing conclusions based on evidence collected
• Writing evaluations that are specific to the investigation

In MATH, students will be learning and practicing the concepts below:

• Number Sense- arrays, prime/composite numbers, factors, factor trees, square numbers
• Place value- whole numbers and decimals
• Rounding – whole numbers and decimals
• Addition/subtraction/multiplication/division word problems
• Estimating answers before calculating
• Converting units of measurement
• Choosing and using appropriate tools to measure
• Accurately drawing given measurements
• Estimating and measuring accurately

Hello to all the new fifth grade students and parents!  I am so excited to be back for another year at ISManila. 

The transition to middle school can be challenging for both parents and students.  Please know that all the fifth grade teachers understand how much there is to learn and adjust to and we are here to offer the needed support.

We will be doing many fun and challenging activities in Math and Science this year, so check back to see what’s going on!
