Butterfly Wings (Compare decimal numbers to hundredths and record the result with the symbols)

Ms. Thomas's fourth-grade class measures butterfly wings for a science experiment. They compare the lengths of two butterfly wings using a place value chart, determining that the second butterfly has taller wings. The lesson then extends to ordering a set of decimal numbers from largest to smallest, emphasizing the importance of comparing digits in the same place value. The video teaches how to compare decimals to the hundredths place.

What is the main objective of Ms. Thomas's fourth-grade class experiment?

• To study the color patterns of butterflies

• To measure and compare butterfly wings

• To compare the wingspan of different birds

• To measure the height of trees

What tool is used to help compare the lengths of the butterfly wings?

• A ruler

• A graph

• A place value chart

• A calculator

When comparing the whole number parts of the butterfly wing measurements, what conclusion can be drawn?

• Both butterflies have equal whole number parts

• The first butterfly has a larger whole number part

• The whole number parts are not important

• The second butterfly has a larger whole number part

In the comparison of the butterfly wings, which digit in the fractional part determined the taller wings?

• The digit in the thousandths place

• The digit in the hundredths place

• The digit in the tenths place

• The digit in the ones place

Which number is the largest among 0.99, 1.23, 5.01, and 1.22?

• 1.22

• 5.01

• 1.23

• 0.99

How do you determine the order of numbers with the same whole number part?

• By comparing the digits in the tenths place

• By comparing the digits in the tens place

• By comparing the digits in the hundredths place

• By comparing the digits in the thousandths place

What is the smallest number in the set 0.99, 1.23, 5.01, and 1.22?

• 5.01

• 1.22

• 1.23

• 0.99
