Check understanding
- Explain why 'for every 2 red beads there are 5 blue beads' can be written as 2:5 or as 2/5 of the blue count
- Identify the multiplicative relationship in a table of values (e.g. y is always 3 times x)
- Connect the ratio a:b to the fraction a/b and to the linear function y = (a/b)x
“Can your child explain why a ratio like 3:4 is really the same as the fraction ¾ — and show how that relationship connects to a straight-line graph through the origin?”
