• Third Grade Standards
    Lakeside Union School District utilizes content standards developed by the state to guide us in designing specific curricular and instruction strategies that best deliver the content to students. Each standard describes the content students should be able to master by the end of third grade.

    1.0 Word Analysis, Fluency, and Systematic Vocabulary Development
    Students understand the basic features of reading. They select letter patterns and know how to translate them into spoken language by using phonics, syllabication, and word parts. They apply this knowledge to achieve fluent oral and silent reading.
    Decoding and Word Recognition
    1.1 Know and use complex word families when reading (e.g., -ight) to decode unfamiliar
    1.2 Decode regular multi-syllabic words.
    1.3 Read aloud narrative and expository text fluently and accurately and with appropriate
    pacing, intonation, and expression.
    Vocabulary and Concept Development
    1.4 Use knowledge of antonyms, synonyms, homophones, and homographs to determine
    the meanings of words.
    1.5 Demonstrate knowledge of levels of specificity among grade-appropriate words and
    explain the importance of these relations (e.g., dog/mammal/animal/living things).
    1.6 Use sentence and word context to find the meaning of unknown words.

    1.8 Use knowledge of prefixes (e.g., un-, re-, pre-, bi-, mis-, dis-) and suffixes
    (e.g., -er, -est, -ful) to determine the meaning of words.

    2.0 Reading Comprehension
    Students read and understand grade-level-appropriate material. They draw upon a
    variety of comprehension strategies as needed (e.g., generating and responding to
    essential questions, making predictions, comparing information from several sources). The selections in Recommended Readings in Literature, Kindergarten Through Grade Eight illustrate the quality and complexity of the materials to be read by students. In addition to their regular school reading, by grade four, students read one-half million words annually, including a good representation of grade-level-appropriate narrative and expository text (e.g., classic and contemporary literature, magazines, newspapers, online information). In grade three, students make substantial progress toward this goal.
