Task
Cruz and Erica were both getting ready for soccer.
Cruz ran 1 lap around the school.
Erica ran 3 laps around the playground.
Erica said,
I ran more laps, so I ran farther.
Cruz said,
4 laps around the school is 1 mile, but it takes 12 laps around the playground to go 1 mile. My laps are much longer, so I ran farther.

Concept/skill: 
Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.

Answer: 
No. This task does not involve comparing decimals to hundredths. Instead, it involves fraction comparisons.

standard_description: Derive the equation of a parabola given a focus and directrix.
problem_activity: Task
Consider three points in the plane, $P=(-4, 0), Q=(-1, 12)$ and $R=(4, 32)$.
Find the equation of the line through $P$ and $Q$.
Use your equation in (a) to show that $R$ is on the same line as $P$ and $Q$.
Show that $P, Q$ and $R$ are on the graph of the equation $y = x^3 + x^2 - 12 x$.
Is it possible for $P, Q$ and $R$ to all lie on a parabola of the form $y=ax^2+bx+c$?
