Grade Two Standards in Language Arts

READING

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  Recognize and use knowledge of spelling patterns (e.g., diphthongs, special vowel spellings) when reading.
      1.2   Apply knowledge of basic syllabication rules when reading (e.g., vowel-consonant-vowel = su/per;
             vowel-consonant/consonant-vowel = sup/per).
      1.3  Decode two-syllable nonsense words and regular multisyllable words.
      1.4  Recognize common abbreviations (e.g., Jan., Sun., Mr., St.).
      1.5  Identify and correctly use regular plurals (e.g., -s, -es, -ies) and irregular plurals (e.g., fly/ flies, wife/wives).
      1.6  Read aloud fluently and accurately and with appropriate intonation and expression. Vocabulary and
             Concept Development
      1.7  Understand and explain common antonyms and synonyms.
      1.8  Use knowledge of individual words in unknown compound words to predict their meaning.

      1.10 Identify simple multiple-meaning 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, news-
papers, online information). In grade two, students continue to make progress toward this goal.

Grade Two Standards in Science

PHYSICAL SCIENCES

1. The motion of objects can be observed and measured. As a basis for understanding
    this concept:

     a. Students know the position of an object can be described by locating it in relation to another object or to
         the background.
     b. Students know an objectís motion can be described by recording the change in position of the object
         over time.
     c. Students know the way to change how something is moving is by giving it a push or a pull. The size of
         the change is related to the strength, or the amount of force, of the push or pull.
     d. Students know tools and machines are used to apply pushes and pulls (forces) to make things move.
     e. Students know objects fall to the ground unless something holds them up.
     f. Students know magnets can be used to make some objects move without being touched.
     g. Students know sound is made by vibrating objects and can be described by its pitch and volume.

LIFE SCIENCES

2. Plants and animals have predictable life cycles. As a basis for understanding this concept:
     a. Students know that organisms reproduce offspring of their own kind and that the offspring resemble their
         parents and one another.
     b. Students know the sequential stages of life cycles are different for different animals, such as butterflies, frogs,
         and mice.
     c. Students know many characteristics of an organism are inherited from the parents. Some characteristics
         are caused or influenced by the environment.
     d. Students know there is variation among individuals of one kind within a population.
     e. Students know light, gravity, touch, or environmental stress can affect the germination, growth, and develop-
        ment of plants.
     f. Students know flowers and fruits are associated with reproduction in plants.

Earth Sciences

3. Earth is made of materials that have distinct properties and provide resources for human
     activities. As a basis for understanding this concept:

     a. Students know how to compare the physical properties of different kinds of rocks and know that rock
         is composed of different combinations of minerals.
     b. Students know smaller rocks come from the breakage and weathering of larger rocks.
     c. Students know that soil is made partly from weathered rock and partly from organic materials and that soils
         differ in their color, texture, capacity to retain water, and ability to support the growth of many kinds of plants.
     d. Students know that fossils provide evidence about the plants and animals that lived long ago and that scientists
         learn about the past history of Earth by studying fossils.
     e. Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials,
         that humans use.

INVESTIGATION AND EXPERIMENTATION

4. Scientific progress is made by asking meaningful questions and conducting careful
     investigations. As a basis for understanding this concept and addressing the content
     in the other three strands, students should develop their own questions and perform
     investigations. Students will:

     a. Make predictions based on observed patterns and not random guessing.
     b. Measure length, weight, temperature, and liquid volume with appropriate tools and express those measurements
         in standard metric system units.
     c. Compare and sort common objects according to two or more physical attributes (e.g., color, shape, texture,
         size, weight).
     d. Write or draw descriptions of a sequence of steps, events, and observations.
     e. Construct bar graphs to record data, using appropriately labeled axes.
     f. Use magnifiers or microscopes to observe and draw descriptions of small objects or small features of objects.
     g. Follow oral instructions for a scientific investigation.
