Fun Valentine's day Project-based learning (PBL) 5th grade! Help your students practice decimals, graphing, multiplication, and division. Includes Math concepts and links to other subject areas. This project will get them out of their seats, happily practicing the Math they've learned this year! Students will put their Math skills to work planning their very own Valentine's Day party, using the guests of their choosing. All of my project-based learning activities come with free e-mail support!
