This is a great activity for anyone learning about area or operations on decimals. Students determine the areas of Christmas trees by using the area formula for triangles and rectangles (multiplying and dividing decimals). In addition, students will be adding and subtracting decimals to determine the total area of the Christmas trees and to determine the amount of change given after purchasing a Christmas tree. Lastly, students will be making comparisons and order the Christmas trees from least to greatest based on their calculated area.
