LESSON 4 Review Comparing Values Learning Targets...

LESSON 4 Review Comparing Values Learning Targets Quick Code I can explain the relationship between place values. egm4004 I can use multiplication to compare place values. ACCESS Relationships Are Important! Think about the relationships among the Base Ten blocks. Use multiplication to describe the relationship between the value of a digit at the start of the arrow and the value of that same digit at the end of the arrow. Start at 1.

How many Hundreds are in 1,000? Think quietly for a moment. Then, record your thinking and share your notes with a partner. Be prepared to share your ideas with the whole group. How many Tens are in 1,000? Think quietly for a moment. Then, record your thinking and share your notes with a partner. Next, work with your small group. Use your Tens rods to help you determine or confirm how many Tens are in 1,000. Be prepared to share your ideas with the whole group.

Be prepared to share your ideas with the whole group. Place Value and the Pharaoh Ant Work with a partner. Use what you know about place value relationships and the Pharaoh Ant to answer the questions. Be prepared to share your thinking with the class. Pharaoh Ant queens lay around 400 eggs throughout their lifetime in batches of about 10. How many eggs will be laid in a year… 1. If there are 10 queens in a colony? 2. If there are 100 queens in a colony? 3. If there are 1,000 queens in a colony? 16 P4_Math_T1_U1_SE.indd Page 16 12/08/21 10:03 AM f-0311 /130/DIS00002/work/indd/Package_from_Client_SE:TE/SE%20inside%20matter/P4_Math_T1...  Work in pairs or small groups to solve problems about place value relationships. Pharaoh Ant Colonies New Pharaoh Ant colonies form through a process called budding. Queens in existing colonies and several workers leave their nest to start new colonies elsewhere. So, a colony that starts with 200 ants can quickly grow times greater to a size of 20,000 ants. A Pharaoh Ant colony can vary in size from a few dozen to several hundred thousand individuals. Imagine a Pharaoh Ant colony consisting of 333,333 ants! 4. In which place is the 3 that has a value 10 times greater than the 3 in the Ten Thousands place? Photo Credit: feathercollector / Shutterstock.com 5. In which place is the 3 that has a value 100 times greater than the 3 in the Ones place? 6. How many times greater is the value of a number in the One Thousands place than a number in the Tens place? Use an example to support your thinking. 7. If there are 12 million Pharaoh Ants on the Kalahari and South America has 100 times as many Pharaoh Ants as the Kalahari, how many ants are in South America? Show your work.

(4 Tens and 3 Ones) x 10 = 2. (2 Hundreds and 3 Tens) × 10 = 3. (7 Thousands and 8 Hundreds) × 100 = 4. (6 Hundred and 4 Tens) x 1,000 = 5. (4 Ten Thousands and 3 Tens) x 100 = 6. Highlight or circle the number that is 100 times greater than 560. 5,600 56,000 Check Your Understanding Follow your teacher’s instructions to complete this activity. 18 P4_Math_T1_U1_SE.indd Page 18 12/08/21 10:03 AM f-0311 /130/DIS00002/work/indd/Package_from_Client_SE:TE/SE%20inside%20matter/P4_Math_T1...
