Adding and Converting Fractions

The video tutorial covers data analysis and fractions for fourth-grade math. It explains how to calculate the range, median, and mode of data sets, and compares fractions of worm lengths. Techniques for adding and subtracting fractions are demonstrated, including using number lines and converting to improper fractions. The lesson concludes with a challenge for students to apply their learning.
