Mini Challenge - Mini Store Challenge

Let's create a fictional mini store to apply our multiplication knowledge!

• Divide into groups of 3 to 4 students.
• Each group will be a mini store that needs to organize its stock and calculate prices.
• Receive a list of toys with quantities and unit prices (for example, 3 dolls at $5 each, 4 cars at $3 each, etc.).
• Multiply the quantities by the prices to find the total value of each item.
• Present your calculations to the class and discuss how you arrived at the results.
