This Place Value Challenge activity is featured in my SMART Notebook series of slides titled "Build, Write, Talk, Compare Large Numbers."
This package includes activity sheets for students to play four rounds. In this Common Core aligned activity students are asked to apply their understanding of place value to create the greatest number possible. Students should be given these activity sheets, two sets of number cards (0-9), and a hundred chart for reference. Students take turns drawing three cards from the pile. They must decide which card to place in the tens position, which card to place in the ones position, and which card to 'trash.' After each partner has created their number, partners must decide who wins the round and circle that partner in the Math Talk portion of the game board.
This activity lends itself to meaningful mathematical conferences as you stop to discuss with students their choices or ask students to explain their thinking during a math discussion at the end of the lesson.
Play this game a second time asking the students to create the smallest two digit number possible! For struggling students provide ten frame models to build representations if needed. Students may need to visualize the number in order to make better choices of which number to 'trash.'
