Lesson Numeration Trillions Genesis :-9 And God said, Let there be lights in the epanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, and let there be lights in the epanse of the sky to give light on the earth. And it was so. God made two great lights, the greater light to govern the day and the lesser light to govern the night. He also made the stars. God set them in the epanse of the sky to give light on the earth, to govern the day and the night, and to separate light from darkness. And God saw that it was good. And there was evening, and there was morning the fourth day. God took great care in creating our world. The massive size of our Solar System gives evidence of the omnipotence of our Heavenly Father. Scientists today measure the distance between planets in Astronomical Units (AU). An AU is the mean distance between the earth and the sun. One Astronomical Unit (AU) is about 9,960,000 miles (9,60,970 Km). Look at the chart below. This chart lists the distances from each planet to the Sun in both Astronomical Units (AU) and miles. Can you read each number correctly?

Lesson 6 Division Many times you can look at a division problem and tell if an answer is too high or too low by using your knowledge of division and multiplication to estimate the answer in your head. Look at the eample below. Karen and Doug were moving from Georgia to Alaska. The trip would cover,000 miles by automobile. If they allowed days to drive, how many miles per day would they need to travel in order to complete the trip in that amount of time? Problem A 00 Problem B ) 00,000 ),000 Is the first answer shown too high of an estimate, or is the estimate too low? Think logically and use your knowledge of multiplication. If rounds down to 0, then 0 00 would be,000. However, Doug and Karen have allowed days. This means that the estimate in problem A of 00 miles per day is too large. What about the estimate in problem B? What is 00? = 8, so 00 =,800. This estimate is too low. The correct answer must be somewhere between 00 and 00. Work the problem to find the actual number of miles they will need to travel each day. 7 R ),000 This means that Doug and Karen will need to drive at least 7 miles per day in order to reach Alaska in days. Tell if the estimated answer is too high or too low. Then find the quotient. 00 ) 00 7, ) 70,96 ) 00, ) 89 80
Classifying and Measuring Angles An angle is two rays that share a common end point. The rays BA and BC are called sides. They meet at verte B to form an angle. The angle can be referred to as ABC, B, or CBA. There are four kinds of angles: B Lesson A C An acute angle. Less than 90. A protractor is an instrument used to measure angles. The angles are measured in degrees. The protractor is marked with 80 degree (80 ) units. An obtuse angle. Greater than 90. 60 0 0 0 0 0 00 A right angle. Equal to 90. 90 80 70 60 0 A straight angle. 80. 0 0 0 L What is the measure of LMN? 70 80 M 0 0 N Follow these simple steps to measure an angle with a protractor:. Place the arrow on the protractor on the verte of the angle.. Place the zero edge on the side of the angle.. Read the measure of the angle. LMN measures 0 Write obtuse, acute or right angle.. 0.. 8 6.. 90 7.. 7 8. Give the measure of each angle. You may need to etend the sides of the angle for easier reading.... 00
