This SMARTboard lesson/activity allows students to determine whether the math sentence can be turned into a true statement if a greater than or less than sign is added. All slides are self checking so this is a perfect activity for either teacher directed mini lesson, small group work, partner work, or even in an independent center. Just move the correct sign ( > or <). Numbers to compare range from a number in the tens to a number in the ten thousands. Most numbers compare a number in the hundreds to another number in the hundreds. Quick and easy to use. Great for introduction, practice, or remediation. Created with Smart Notebook 11.
