    Warm-Up

    Give your child a 40-inch piece of string and ask them to measure and cut it into two pieces where one piece is 16 inches. They predict the second piece's length (24 inches), cut, and measure to check.

    Mini-Lesson: The Paper Chain Plan

    Set a goal: build a paper chain to reach across a doorway. Measure the doorway together (for example, 32 inches), then make three links and measure how long the three-link chain is (about 6 inches). Ask: 'How many more inches do we need?' and write 32 - 6 = 26.

    Practice: Build and Track

    Your child adds links, stopping every 5 links to measure the chain and write an equation for how much is left (for example, chain is 18 inches, 32 - 18 = 14 inches still needed). When the chain is longer than the doorway, they measure the extra and write the subtraction (for example, 36 - 32 = 4 inches too long). Then they write their own word problem about the chain for you to solve.

    Wrap-Up

    Hang the chain and read your child's word problem aloud, solving it while they check your work. Ask: 'Which equation did you use most today, adding or subtracting?'

    Shared Reading

    Reread the pages in Gibbons's 'Penguins!' about the different species (emperor, king, Adelie, rockhopper). Your child reads the species names and one fact about each. Ask, 'Which penguin is the largest? How do you know?'

    Mini-Lesson: Writing a Question and Answer Page

    Show a question and answer page from any nonfiction book, or make one on paper: a bold question, then a two-sentence answer. Explain that authors use this format to help readers find facts fast. Model one: 'Q: Why are penguins black and white? A: The book says the colors hide them from predators. From above they look like dark water; from below they look like light sky.'

    Writing Workshop: Penguin Q and A Booklet

    Fold two sheets into a booklet. Your child writes three question and answer pairs about penguins (one who or what, one where or when, one why or how), each answer using the book. Then they edit for the week's grammar: at least one collective noun and one irregular plural, both spelled correctly.

    Word Study: Mixed Irregular Verbs and Words

    Play a quick game: you say a present verb from this week's lists and your child says the past; then flip and you say a wall word ('friend,' 'because,' 'again') and they spell it aloud. Finish with the dictated sentence 'My friend said the geese flew away again.'

    Review and Extend

    Read 'Giving Thanks: A Native American Good Morning Message' by Chief Jake Swamp, a Mohawk elder of the Haudenosaunee. Ask: 'What parts of nature does the message thank? Why would a people who farmed corn, beans, and squash take care of the soil and water?' Connect to science: the same rivers and hills on Wednesday's map are the resources the message names.

    Project Work: Three Sisters Garden Plan and Thanks Poster

    Explain that the Haudenosaunee planted corn, beans, and squash together, called the Three Sisters, because the corn holds up the beans and the squash leaves shade the soil. Your child draws the three plants growing together in a mound, labels each one's job, and writes three lines of thanks in their own words for things from nature they use every day (water, sun, a tree).

    I can use adding and subtracting to plan a real length.

    Look: How much more chain?

    1. The door is 30 inches wide. The chain is 12 inches long.
    2. How much more? 30 − 12 = 18.
    3. We need 18 more inches of chain.

    Build a paper chain to reach across a doorway. Measure after every 5 links.

    LinksChain length (inches)How much more? (equation)
    1. My doorway is ________ inches wide.

    Solve. Write an equation.

    1. A chain is 14 inches long. The doorway is 34 inches wide. How much more chain is needed?
    2. Now the chain is 38 inches long. The doorway is 34 inches wide. How much too long is it?
    3. Write your own word problem about your chain.

    You need: paper strips, tape or glue, a ruler or tape measure
