Mild:
Can you think of a reason why each domino could be the odd one out in the group:
Medium:
Naomi went shopping with money she had saved. At the first shop she visited, Naomi gave half of her money to the shopkeeper to buy a pencil case. He gave her $4 back in change. Then Naomi bought a book for $10 and a keyring for $6. She had $3 left. How much money did she start with?
Spicy:
Can you work out what the value of the 4 different colour shapes. Each colour shape has the same numerical value. However, every colour has a different numerical value. Can you work out the value of each colour so that the mobile is balanced.
