Lesson Plans - Teaching Ideas

• Start by selecting only the sums 3c and 30c (or 3€ and 30€) and enable help level 1. Record the operations on paper alongside the game to help students understand how adding a zero affects the value of the number.

• Progress gradually to the remaining pairs of sums: 4c-40c/4€-40€, 6c-60c/6€-60€, 7c-70c/7€-70€, 8c-80c/8€-80€, 9c-90c/9€-90€. Maintain parallel recording of operations to reinforce understanding of place value.

• In the next step, first combine all sums from 3 to 9 (euro and cent operations in units) and then all sums from 30 to 90 (euro and cent operations in tens).

• Focus on a specific sum (e.g., 6c) and explore all possible combinations: 5+1, 2+2+2, 2+2+1+1, 2+1+1+1+1, 1+1+1+1+1+1. Create a list of all possible combinations in advance as a guide.

• Use different combinations of coins and banknotes for the same target. For example, the sum of 50€ can be achieved with various combinations of 10€ and 20€.

• Encourage students to develop quick calculation strategies. For example, when they see the target of 60€, they should immediately think of the quickest combination (50€+10€).

• Connect the game to real shopping situations. For example, "If we want to buy something that costs 90€, what combinations of banknotes could we use?"
