Fraction symbols can usually be safely introduced

A. at the beginning of third grade.
B. near the end of first grade.
C. near the end of third grade.
D. at the beginning of second grade.

my answer is c.

I would say A

Your answer is correct! Fraction symbols are usually introduced near the end of third grade.

To determine when fraction symbols can usually be safely introduced in elementary school, we need to understand the progression of mathematical concepts in the curriculum.

In the United States, the Common Core State Standards for Mathematics serve as a general guideline for the order of topics taught in each grade. According to these standards, fractions are first introduced in the second grade and continue to be developed through third grade.

In second grade, students are introduced to the concept of fractions as part of a whole. They learn to partition shapes into equal parts and identify fractions like halves, thirds, and fourths.

In third grade, students build upon their understanding of fractions and develop a deeper knowledge of fraction symbols. They learn to represent fractions using number lines and in equations, compare fractions, and perform basic operations with fractions.

Based on this information, the correct answer to the question is C. Fraction symbols can usually be safely introduced near the end of third grade, as students have already mastered the foundational understanding of fractions by that point.
