Time Problems in Context
In this time problems in context activity, students solve 40 real life telling time problems. Students use timetables to calculate travel times and also use a pay scale to figure out weekly earnings in English pounds and pence. This page...
Balanced Assessment
Dinner Date
Determine just how far to run before dinner. The short assessment asks pupils to determine the distance a person can jog in the time left before dinner. To answer the question, scholars determine the distance if the person jogs one way...

The Babylonian Algorithm, Limits and Rates of Change
In this successive approximations worksheet, students use the Babylonian algorithm to determine the roots of given numbers. They identify the limits of a function, and compute the rate of change in a linear function. This two-page...
Curated OER
Not Your Average Average
Students discover that if a distance is traveled in two or more segments at different average speeds, you cannot average the average speeds. Instead the total distance traveled must be divided by the total elapsed time. Students practice...

Euler's Method
In this Euler's method worksheet, students use Euler's method to determine one-second time intervals in a rate problem. They explore functions to estimate rate changes in small time intervals. This two-page worksheet contains...
Curated OER
Travel Time
Students use a migration map to estimate the distance traveled by a bird while migrating south. After calculating accurate estimates of the distance traveled, students compare the distances traveled with the amount of time elapsed.
