HealthCenter21: Medical Mathematics

This module provides a review of math skills frequently used by health care workers. Students review basic numerical concepts, including whole numbers, decimals, fractions, percentages, estimates, and measurements using the household, metric, and apothecary systems. Students practice using ratios and proportions to convert between measuring systems and calculate medication dosages, read labels and prescriptions, and learn how temperature and time are used in health care. Students record an Intake and Output chart and a TPR graph.
