Three 60-minute lessons and classroom activities in which students will: 1) apply knowledge of whole numbers and place value by identifying the place value of a digit in a whole number; 2) compare numbers using the greater than, less than, and equal symbols.

Students will develop a sense of the size of a number in relation to other numbers. Prior to these lessons, students should have learned to read, write, and use base-10 blocks to represent 2 digit numbers (place value models). In these lessons, students will continue to use manipulatives to represent two digit numbers and compare the numbers using the >, <, = symbol. A summative assessment is included.

This is a mathematics competition open to all U.S. middle and high school students. Problems are published on the website four times a year one month before solutions are due. Problems range in difficulty from being within the reach of most high school students to challenging the best students in the nation. Students may use any materials -- books, calculators, computers -- but all work must be their own. This year's special topic is expected value.
