Mathematics
Cillian made groups worth $1 using nickels and quarters, practicing how coin values combine to make a target amount. Cillian connected the value of a nickel (5 cents) and a quarter (25 cents) with the dollar (100 cents), and explored that the same total could be built from different combinations. This activity strengthened skip-counting by 5s and 25s, addition, and understanding money as a way to represent quantities. Cillian also practiced grouping and checking whether a collection of coins reached the required total.
Tips
Tips Extend Cillian’s money thinking with a pretend shop: label small items with prices and let Cillian pay using nickels and quarters, then explain how the coins add up. Use a hundred-chart or coin-value number line to trace counts by 5s and 25s toward 100 cents. Invite Cillian to find several different coin combinations for $1 and compare which use more coins or fewer coins. For a real-world connection, sort clean coins by type and make a visual display showing how each coin contributes to the dollar.
