The visual approach (show more)
- The student is able to use images and/or objects to represent a problem and find a solution.
Prompts from the teacher could be:
- What do you know about the cards?
- Whose cards could you work out next?
- What does fewer mean? Do you know another word like that?
- How are you keeping track of what you work out?
- What do you notice about the number of cards each person has?
The conceptual approach (show more)
- The student is able to solve a problem using sharing and other strategies, to find unknown addends.
