Third Grade is the crucible for beginning critical thinking skill, developing depth of knowledge, and using common math sense. It is the final grade where students primarily focus on the basics of base ten adding, subtracting, multiplying, and dividing. Fourth grade introduces multiplying two-digit numbers, and fifth grade spends much of the year on fractions and decimals. Third grade is the last best time to follow a path that will eventually lead to solving "y - 0.2 = 0.75" as easily as solving 75 cents plus 25 cents.
