Students will be able to describe the steps to add multiples of 10 to two-digit numbers within 100 using drawings of ten and one dollar bills.
Introduction
- Tell students, "I have four 10 dollar bills and two one dollar bills. The principal has two 10 dollar bills and four one dollar bills." Ask students, "Who has more money, me or the principal?"
- Instruct students to turn and talk to a partner to discuss.
- Invite students to share how they know who has more money. List ideas, such as drawing a picture or comparing the amount of tens and ones in the two numbers, on the board.
- Write the answer, "Since 42 is more than 24, the teacher has more money." on the board. Have students repeat the answer after you.
