Day 2 (Preparation: Review or teach reading numbers larger than 1 000.)

• Rule out the use of 0 as a first digit in today’s work.
• Write a three-digit number with 5 in the tens place. Ask each student to read the number written by the student on the right. Ask questions of the whole group, for example: Which number is largest? Smallest? What is the largest possible correct answer? Smallest? When many students write the same number, is it because they don’t have many choices of correct answers?
