This week we will have Chick-Fil-A spirit night on Monday. A portion of the profits will go to our school. It is an Early Release day on Wednesday. And we will have school pictures on Friday. These pictures will be used in the year book so bring your best smile.
In math this week we will finish up our work with factors, multiples, prime numbers and composite numbers. We will learn all about ancient Greek mathematician, Eratosthenes. Eratosthenes developed a way to separate prime numbers from composite numbers. His sieve can be used to find all of the prime numbers from 1-100! See the movie on the math websites page.
We will also learn about area and perimeter. We will build upon what students learned in 3rd grade. In 4th grade students will have to apply the area and perimeter formulas to solve real world situations. Students will have to solve simple problems such as
and more complex problems such as
and
In science we will begin our study of matter. Students will learn about how we use the properties of matter to identify an object. The properties of matter include:
*mass
*volume
*attraction to magnets
*shape
*size
*texture
*color
Students will also learn the difference between mass and weight. Mass is the amount of matter contained within an object. Weight is the force of gravity on an objects mass. An objects mass stays the same unless something happens to the object to change it. An objects weight will change depending on the amount of gravitational force on the object.
This week in social studies we will finish up chapter 2. The test on chapter 2 will be Friday October 7th. The vocabulary for chapter 2 will be due on that day.
Have a GREAT Week,
Aesha
