Generating a Number Greater or Less Than a Given Number
T.I.P.S.
Students should rely on their prior knowledge from first grade related to generating a number that is greater than or less than a given whole number up to 120. Students will now apply this concept to find a number more than or less than a given number up to 1,200. Students could use objects such as base-ten blocks, drawings or pictorial models, hundreds chart, number line, or comparative language to generate a number more than or less than a given whole number.
Example
Complete the following statements and justify your solutions using place value models or a number line.
a) 10 more than 239 is ________. b) 100 less than 524 is ________. c) ________ more than 352 is 362. d) Find a number that is more than 1023 and less than 1200. e) Find a number that is more than 709 and has a 9 in the tens place.

2.2 Number and operations. The student applies mathematical process standards to understand how to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to: (C) generate a number that is greater than or less than a given whole number up to 1,200Feedback
