Original Prompt

Crete a practice worksheet with the following types of questions as practice for a quiz: Joanne has three shirts: orange, blue, and yellow. She also has two pairs of pants: khaki and blue jeans. Finally, she has the choice of either dress shoes or sneakers. How many different combinations of outfits can she make? Draw a tree diagram, area model, or other visuals to show the possible outcomes.

This resource focuses on the Fundamental Counting Principle (FCP), illustrating how to solve counting problems through visual representations such as tree diagrams and area models. It begins with defining the FCP—explaining that if there are m ways to make one choice and n ways to make another, then there are m × n total combinations. The tutorial offers hands-on examples like Joanne's outfit choices, guiding students through multiplication of options and visualizing combinations via tree diagrams and area models. Guided practice problems enhance understanding, followed by deeper probability modeling scenarios in a cafe and sneaker design, where students can apply the FCP in real-life contexts. The resource emphasizes practice and visualization to solidify comprehension.
