Activity 01
Pairs Challenge: Shopping Budget Calculator
Pairs list 5-6 grocery items with prices in column A and quantities in B. They enter =A2*B2 in C2, drag to fill down, then use =SUM(C2:C7) for grand total. Partners change a price or quantity and observe updates, noting predictions first.
Analyze how cell references allow for dynamic and flexible calculations.
Facilitation TipDuring the Pairs Challenge, circulate and ask each pair to demonstrate how changing a price updates the total cost, reinforcing the link between cell references and live results.
What to look forProvide students with a simple spreadsheet containing two columns of numbers (e.g., quantities and prices). Ask them to write a formula in a third column to calculate the total cost for each item, then change one of the prices and ask them to predict the new total.
