Learning objective
What this activity builds
Recognize equivalent multiplicative relationships in contextual data, even when the quantities differ.
Worked example
Mix A uses 2 scoops of concentrate and 6 scoops of water. Mix B uses 3 and 9. Mix C uses 4 and 10. Which pair has the same concentration ratio?
Mix A and Mix B: both have concentrate:water = 1:3.
2:6 and 3:9 both reduce to 1:3. Mix C reduces to 2:5, so it represents a different relationship even though its quantities are larger.
Teaching notes
Make the practice count
- Read the column headings before comparing any numbers.
- Check every candidate pair; visual similarity in the raw values is not enough.
- Have learners annotate each row with its simplest ratio before choosing the pair.
- The three-problem option is useful for discussion; the six-problem option gives another page of practice.
