1. 2. <ul><li>Units of measurement were among the earliest tools invented by humans. Primitive societies needed rudimentary measures for numerous tasks such as: constructing dwellings of an appropriate size and shape, fashioning clothing, or raw materials. </li></ul><ul><li>Length is a measurement of distance or dimension. The two main systems to measure length are the metric and the English system. </li></ul><ul><li>We need frequent and repeated opportunities to practice and apply measurement. There are four primary units used for length or distance: kilometers (km), meters (m), centimeters (cm), and millimeters (mm). 1000 meters = 1 kilometer 100 centimeters = 1 meter 10 millimeters = 1 centimeter </li></ul>
2. 4. 10 millimeters (mm) = 1 centimeter (cm) 10 centimeters(cm) = 1 decimeter (dm) = 100 millimeters (mm) 10 decimeters (dm)= 1 meter (m)= 1000 millimeters (mm) 10 meters (m) = decameter (dam) 10 decameters( dam)=1 hectometer (hm) =100 meters (m) 10 hectometers=1 kilometer(km) = 1000 meters (m)
3. 5. <ul><li>Bichacue Yath Farm </li></ul><ul><li>It’s a 30-45 minutes (17km) drive from Cali city center to the nearby rural mountain town of La Leonera, where you can visit the excentric story telling mountain man Thomas and his wife in their magic and mystic garden.

Help us complete the following information for the transportation section. </li></ul><ul><li>TASK 1: Find the distance covered from Cali to La Leonera in Km, Hm, Dm and M. Justify your answers. </li></ul>
4. 6. Task 2: Task 2: To go to Bichacue Yath Farm we must pass by many places like Portada al Mar, Saladito and, Felidia. Complete the following chart. Km Dm Hm Saladito-Felidia 3 Felidia-Leonera 3 Portada al Mar-Saladito 11
5. 7. <ul><li>Task 3. Mr. Tomas, who is the owner of the Bichacue Yath Farm, digs 6 rows of earth to plant trees. The rows are 3 meters long. What length of ground has he dug altogether? Give your answer also in dm. </li></ul>

7. 9. <ul><li>Task 5 . Your new friend from Bogota made many trips from Saladito to Felidia (3Km). He needs to complete the following chart to find out the distance he traveled: </li></ul>TRIPS DISTANCES IN km DISTANCES IN m 1 _______ 12.000 5 8 _______ 39
8. 10. Task 6: <ul><li>One of Mr. Tomas helper has a 1, 20 meter long piece of wood. He wants to cut it into 3 equal lengths. How long should each piece be in millimeters? </li></ul>
9. 11. <ul><li>Task 7. Think and answer the following questions: </li></ul><ul><li>When are km, m, cm, Dm used? Example. </li></ul><ul><li>_________________ are used for very long distances. </li></ul><ul><li>  Task 8: Choose the appropriate units to measure: a) the length of objects such as eraser, pencil or book, b) the length and height of your teacher’s table, c) the length and width of your classroom, d) the heights of your friends. </li></ul><ul><li>Task 9: Write 2 complete conclusions about units of lenght. </li></ul>
