Math Update!

We've covered many topics in Unit 6, including: 

How to express and interpret remainders in division (remainder OVER divisor)

When to pay attention to remainders and when to ignore them, based on the question being asked

How to measure and draw angles using a FULL CIRCLE PROTRACTOR

How to measure and draw angles using a HALF CIRCLE PROTRACTOR 

Identifying ACUTE, OBTUSE, REFLEX, STRAIGHT, and RIGHT ANGLES

Using Rectangular Coordinate Grids to find areas/points on a map

Using ordered pairs to identify and locate points on a map

We are currently working on understanding the GLOBAL COORDINATE GRID SYSTEM on a globe and map. Before we began, we gathered information on what we already know, and then shared some questions of what we'd like to find out. Here's what we came up with:

What we know:

Globe/Sphere is round (Adam)

There's life on earth (Joshua)

There are time differences (Daniel G.)

Globe shows continents and oceans (Daniel G., Rochel, Daniel K.)
Earth mostly covered with water (Alice)
There's a North and South Pole (Daniel G.)
Equator (Daniel K.)
Variations in weather and climate (Alice)
Top & bottom is colder (Alice)
Middle is hotter (Alice)
Blue represents water, and the rest is for landforms (Rachel)
Countries are represented with different colors (Rachel)
Latitude and Longitude are lines on the globe (Noah)
There's a Northern Hemisphere and a Southern Hemisphere (Noah)
Main line of latitude is the equator (Noah)

What we want to know:
What are the lines for? (Rachel)
How many countries and languages are there? (Daniel G.)
Are continents flat or 3-D? (Adam)
Why does the globe show so many countries? (Joshua)
How does time change? (Alice)
What is inside Earth's core? (Daniel K.)

In the lesson, we covered the following topics. It would be great if you discuss these at home, and practice finding locations on the map using the degrees North/South of the equator (LATITUDE), and degrees East/West of the PRIME MERIDIAN (LONGITUDE):

NORTH POLE, SOUTH POLE, and AXIS

EQUATOR

PRIME MERIDIAN

HEMISPHERES (Northern and Southern, Eastern and Western)

LINES OF LATITUDE (Full Circles, and they are parallel to the Equator)

LINES OF LONGITUDE (Semi-circles, and they are not parallel to the Prime Meridian because they meet at the North and South Poles)

We also learned that each degree represents 70 miles. So to find the distance in miles you need to multiply your number by 70...
