https://reurl.cc/aL0veZ I believe it depends on how it's used, although either usage is fine in modern English. "Fifth grade" is a noncount noun, therefore doesn't require a definite article. "American students study geography in fifth grade." However, noncount nouns, when plural, take the definite article if referring to a defined or specific group. Therefore when a speaker is referring to their specific experience, they may appropriately use the definite article. "I studied geography in the fifth grade." At least that's how I learned it. https://reurl.cc/prny98 -- 【sik-sut蟋蟀；tshiok-tsit促織(文)；gim5-khiong5吟蛩(文): cricket】【too7-kau5 杜猴: Formosan giant cricket 台灣大蟋蟀(華語)】【too7-peh-a2杜伯仔: mole cricket 螻蛄(華語)】【tsiong-su螽斯: katydid, bush cricket】【oo-liong5烏龍: black katydid 黑色的螽斯(華語)】 --
