    Activities

    10 min

    Warm-Up

    Set out a quarter coin and ask, 'How many quarters make a dollar?' (4). Say, 'A quarter is one of four equal parts. Today we cut shapes into quarters.'

    15 min

    Mini-Lesson

    Fold a paper circle in half and then in half again to make four equal shares. Say, 'Four equal shares are called fourths, or quarters. This is one fourth. This is two of the fourths. This is three of the fourths. Four fourths is the whole.' Repeat with a paper rectangle.

    15 min

    Practice

    Your child cuts a tortilla or paper plate into fourths and draws four rectangles showing fourths in different ways: four strips, a plus sign, an X of diagonals, and two rows of two. They color two of the fourths on one rectangle and label it 'two of the fourths.'

    5 min

    Wrap-Up

    Ask, 'Which is bigger, one half of the tortilla or one fourth?' Lay the pieces on top of each other to check, and note that more shares means smaller pieces.

    Mini-Lesson: Moving the Phrase

    Write 'The beaver swam under the pond.' on a sentence strip, cut off 'under the pond,' and move it to the front: 'Under the pond, the beaver swam.' Show that the meaning stays, the capital letter moves, and a comma appears. Your child rearranges 'The loon called over the water.' both ways.

    Guided Reading: Who Eats Whom?

    Read the author's notes at the back of the book for four animals and find who eats what (for example, a heron eats fish, fish eat insects, an otter eats fish). Your child draws the animals and three arrows for a food web, matching this week's science. Support: you read the notes and your child draws the arrows. Stretch: your child adds a plant to the bottom of the web and explains why.

    Writing Workshop: Compound Sentences

    Show how to join two sentences with 'and,' 'but,' or 'so': 'The loon dove, and the minnows scattered.' Your child writes four compound sentences about the pond, one with each joining word plus one free choice, and reads each aloud to hear the pause at the comma.

    Word cards: found, gave, goes, their, there, these, those, upon, very, would. Read three times for time, then your child reads one page of 'Over and Under the Pond' for one minute while you count words read; write the number down to compare Thursday.

    Read-Aloud and Discussion

    Read 'Alexander, Who Used to Be Rich Last Sunday' by Judith Viorst. Keep a running count of Alexander's money on a whiteboard as he spends it (start at one dollar, subtract at each stop). At the end ask, 'What did Alexander want most? Why could he not get it?' Define scarcity: there is not enough money, time, or stuff to have everything we want, so we must choose.
