What's Happening

Week of September 11-15

MATH

Adding and Subtracting Fractions

numerator  the top number of a fraction.  This number tells how many parts of a whole there are

denominator  the bottom number of a fraction.  This number tells how many parts the whole is divided into

When adding and subtracting fractions, the numerator is added but the denominator is not.  

2/5 +  2/5 = 4/5

4/8 – 3/8 = 1/8

 

SCIENCE

Energy Transfer

EGG DROP Friday September 15

students can make egg drops out of anything except peanut butter jars and flying drones.  Let your imagination run with this one.  Check out Youtube, there are lots and lots of egg drop ideas.

Students need to know these terms

Thermal Energy – type of kinetic that depends on movement of tiny particles

Nuclear Energy – potential energy that is stored in links between protons and neutrons of atoms and require a nuclear reaction to release the energy.

Chemical Energy – energy that is stored in links between atoms and molecules.  Only released by a chemical reaction such as heat or when our bodies digest food.

Sound Energy – sound is a type of energy produced by vibrations and travels on waves.

Light Enegy – energy is carried on waves.

Electrical Energy – energy that comes from movement of charged particles.

Conduction – the transfer of thermal energy between two objects that are touching.

Conductor – a material through which heat or electricity flows easily.

Convection – the transfer  of thermal energy by flowing gases or liquid, such as the rising of warm air from a heater.

Insulator – a material that slows or stops the flow of energy, such as thermal energy, electricity and sound.

Heat – the movement of thermal energy from a warmer object to a cooler object.

Radiation – the transfer of energy through space.

 

Week of August 14 – 18

MATH

Math basics in review

Adding and subtracting 2 and 3 digit numbers by regrouping. 

Sound difficult?  Do not let the terms scare you.  Basically we are adding by carrying and subtracting by borrowing 2 and 3 digit numbers.

Example:   Addition

          1

              32            2 + 9 = 11 carry the 1

               +19            1 + 3 + 1 = 5

             51

 

               Subtraction

          64   

-17      You cannot subtract 4 – 7 so you have to borrow  from the 6, so the 6 becomes a 5 and the 4 becomes 14

5 6 14

        -17          Now you subtract 14- 7 = 7 and 5-1 = 4 and the answer is  

           47

           

          Multiplication Facts

Students are reviewing and mastering multiplication facts.  This week, students are responsible for knowing their multiplication facts from 1 – 12 for their 2’s, 3’s, 4’s and 5’s.

 

Don’t be embarrassed if you ever have trouble with your child’s math or science homework.  I will be happy to meet with you in person or over the phone to explain it so that you can help your child.  I’ve got kids too and even though I am a teacher, there are times I need to relearn something also. 

 

SCIENCE

          This there is a Solar Eclipse on Monday August 21, 2017, this week we are learning about how and why eclipses happen.  This is perfect because students are also learning how to make their science journals, which are where they keep all of their class notes.  The information about the eclipses provides perfect note taking and classroom procedure learning opportunity.

Your child should now be able to explain to you what a solar eclipse is, how it happens and the different types of eclipses. 

Solar Eclipse – when the earth, moon and sun line up in a straight line which causes the sun to cast a shadow on the earth.  This eclipse is special because it is the first totality eclipse in 99 years.  Totality means complete darkness will occur for a few minutes!

Annular Eclipse - when the earth, moon and sun line up in a straight line which causes the sun to cast a shadow on the earth but complete totality does not happen.

Partial Eclipse - when the earth, moon and sun line up but not in a straight line which causes the sun to cast a smaller shadow on the earth.

 

Make sure you have signed the permission slip that was sent home this week so that your child may view the eclipse on Monday August 21, 2017 at 1:09 pm.
