10th Grade Vocabulary Words

Tenth-grade reading asks learners to move confidently among literary analysis, argument, source evaluation, laboratory science, mathematics, computing, history, economics, psychology, philosophy, and the arts. This level emphasizes precise academic language, disciplinary meanings, connotation, word relationships, and the ability to interpret unfamiliar vocabulary in demanding context.

This independently authored 800-word beta curriculum is arranged in twenty-three pages of up to thirty-five words. Pages containing words 1–500 include five cloze questions drawn only from that enhanced range; words 501–800 remain fully visible and editable as list pages while expanded practice is developed. Every row includes an editable subject-field label and a conservative word-study note about transparent affixes, compound structure, capitalization, or dictionary base forms. The cited sources calibrate range and difficulty only; all learner-facing definitions, examples, quizzes, and descriptions are original KSSR copy.

Please note: the vocabulary lists for grades 9~11 have been selected to ensure no overlap with the previous grade level. If the words are too specialized or difficult for you, please go back to grade levels 4~8 and review the words on those pages.

Vocabulary reading and practice

Designing a Sampling Study

Reading practice for pages 1–3. Five relevant words are highlighted.

English reading

A conceptual framework connects neighborhood design, travel choices, and air quality. Researchers use stratified sampling so every district is represented, then apply random sampling within each district. They compare independent samples of commuters and remote workers. Their alternative hypothesis predicts a difference in average exposure, while the null hypothesis predicts none.

Reading comprehension

1. Why use stratified sampling?

It ensures that every district is represented.

2. Where is random sampling applied?

It is applied within each district.

3. What does the alternative hypothesis predict?

It predicts a difference in average exposure.
