Why do Grades 3 and 4 use the same ruler, since the Grade 3 Performance Indicators address only standard (and not metric) measurements to the nearest 1/2 inch?
Two sets of punch-out tools were developed (one for grades 3 and 4 and the other for Grades 5 through 8). One common punch-out card is used in Grades 3 and 4 because all features on the card, including the ruler, can be used in both grades, even though metric measurement is also present on the ruler.
