Show students how to play Different Ways in pairs:
- Students take turns rolling two dice. One die represents the number of rolls in their collection and one die represents the number of loose lollies in their collection (students can pick which is which each turn). The student uses cubes to represent the total number of lollies.
- Both students record the total number of lollies on Different Ways Student sheet.
- The other student uses cubes to represent the same number in a different way.
- If both students agree that the two representations look different but are equal in value, they both record the two different representations and the total number of lollies on their student sheet.
- Annika rolls two dice and gets a 2 and a 4. She decides that this represents 2 rolls and 4 loose lollies. She gathers 2 rolls of 10 cubes and 4 loose cubes from the collection of cubes.
- Annika and Beau both record the total number of lollies on their student sheets: 24.
- Beau needs to find another way to represent 24. He uses 1 roll and 14 loose cubes.
- Annika and Beau agree that their representations are different but equivalent in value. They record the two different representations on their student sheets.
- They play again, this time with Beau rolling the dice.
