This is a wonderful way for students to practice finding the better buy using a real-world example. Students will respond to a word problem written in letter format, asking for help finding the better buy. Students will respond to the letter, practicing letter-writing skills, as well as mathematical skills! Additionally, students will get to practice explaining their math thinking. This is a fun activity for 5th graders and 4th graders who want a bit of a challenge. Keep an eye on my TPT
