#### Learning Objectives

Students will be able to subtract decimals to the hundredths place.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

(3 minutes)
• Review decimal basics by writing a decimal number to the tenths place on the board (e.g., 2.4).
• Call on a student to read the number and tell you the value of the number in the tenths place (four-tenths). Tell students that the tenths place is the first digit to the right of the decimal point and represents one out of ten equal parts of a whole.
• Write a decimal number to the hundredths place on the board (e.g., 4.56).
• Call on a student to read you the number and tell you the value of the number in the hundredths place (six hundredths). Tell students that the hundredths place is to the right of the decimal point and represents one out of one hundred equal parts of a whole.
• Tell students that today they will practice subtracting decimals.

Beginning

• Have students repeat and rephrase the definition of decimals and the tenths and hundredths place values to a partner.

Intermediate

• Give students access to the vocabulary cards of the pertinent terms related to the lesson to keep on their desks for them to use a reference.
