In fourth grade I learned decimals. Decimals are my favorite math subject,I like it because I have fun with it and because it is easy to learn fast for me. Second I learned long division,I like long division too because it is easy for me . My teacher taught me by watching long division in a song like Gangamstyle. Third I learned how to find the volume of a 3-D shape by multiplying the length times width times height. Fourth I learned about figuring out the time and making a chart to know how many minutes.seconds,or minutes it could or would take. Now the last thing I learned from 4th grade was about rounding the tenths place and hundredths place.
That is all that I learned in 4th grade.
