Multiplying Decimals by Decimals

A huge part of Common Core Math is using models or drawings.  We have been learning how to multiply decimals to the hundredths place.  This video shows us how to multiply decimals by decimals using the area model.

What is a coordinate plane?

So glad you asked!!!  Watch this video to learn what about coordinate planes and how they are like a vertical and horizontal number line.

Genetics Vocabulary

characteristics	quality of an organism
DNA	material in life forms that transfer genetic characteristics
inherited	characteristics from parents
likeness	similarity
organism	individual living system
traits	distinguishing characteristics

What are inherited traits?

Inherited traits are specific characteristics you are born with.  These traits come from your parents.  Watch the video to get more information.

Polygon Attributes

We have been identifying attributes of polygons and using that information to sort them.

Polygon Attributes

Triangles

Triangles can be sorted into categories.  Watch the Study Jams video to explore the different types of triangles and their attributes.  Be sure to test yourself at the end.

Polygons

We have begun identifying and sorting polygons into categories.  I hope are having fun because math is fun! Click on the link below to learn more about polygons.  Scroll down to the middle of the page and look for "Play With Them!" to play with interactive polygons.  You can create all the different types of polygons we have been learning about.

Writing Decimals in Expanded Form

This is an excellent video to explain writing decimals in expanded form.  It focuses on using unit fractions, but we have also learned the alternate way shown in the video.  Either way is acceptable.

Rounding decimals to the nearest hundredths place using number line

Watch the video below as a reminder about rounding decimals to the nearest hundredths place using a  number line.  

Rounding decimals to the nearest hundredths place using number line

Rounding decimals to the nearest tenths place using number line

We have worked hard to understand decimals.  Watch the following video to learn to round decimals to the nearest tenths place using a number line.

Rounding decimals to nearest tenths place using number line

Rounding decimals to nearest whole number using number line

In the past week, we have been working with decimals.  We have learned to understand decimals using base ten pieces, base ten grids, place value charts and number lines.  We have learned to read and write decimals in standard form, and expanded form.  Watch this video to learn how to round decimals to the nearest whole number using a number line.

Welcome Back!

Welcome back fifth grade students and parents!  I am very excited about teaching math and science.  I look forward to an exciting and successful year.  Check back often for updates and new material to support your learning.

May is National Inventors Month

During this month, we celebrate the hard work and effort of inventors who have inspired us to think outside the box!

Simple Machines

Click on website below for a simple machines game.  Explore the house and tool shed to identify all the simple machines we use on a daily basis to make our work easier.  Be sure to read the information following your answer choice to learn more about each type of simple machine.

Motion and Design

Welcome to Fourth Quarter!  This quarter, our unit of study will be Motion and Design.  We will be exploring the motion of objects and the engineering process.  For some background knowledge on how things move, listen to this song on simple machines.  They are not explicitly taught in fifth grade curriculum, but I feel they are important in order to have a full understanding of motion.  Enjoy!

Reason for the Seasons

In class, we read about James and Sophia.  In North America, James was experiencing winter during the month of February.  In Australia, Sophia said it was summer in February.  How is this so?  Watch the video to understand the reason for the seasons.

Convection Current

Watch the video to see a convection current.  In this example, you will observe how hot and cold water move in the fish tank.  The water moves in the same manner as air.  Since warm air is less dense than cool air, warm air rises, leaving space for the cool air to sink and take it's place.  Convection currents happen as a result of uneven heating of the Earth's surface (when it is warm in one place and cooler in another location). 

Air Pressure vs Altitude

How are air pressure and altitude related to one another?

Temperature and Altitude

What happens to the temperatures as you go higher in elevation?
