What's more romantic than a bar graph on Valentine's Day? In this Valentine's Day lesson plan, students will use information from a data set to create their own tally charts and bar graphs and then analyze these graphs to answer questions.

Use this hands-on lesson to encourage collaboration amongst students as they review base-ten numerals, number names, and expanded form. This lesson can be used as a pre-lesson to Base Ten Block Party or as a stand-alone activity.
