    Warm-Up

    Mental math ladder: start at 384. Your child adds 10 (394), adds 100 (494), subtracts 10 (484), adds 10 (494), adds 10 (504), subtracts 100 (404). Then a new ladder from 296: add 10, add 10, add 100, subtract 10 (306, 316, 416, 406).

    Mini-Lesson

    Mixed model: solve 458 + 367 with a base-ten drawing (825, two regroupings) and 703 - 456 (247, unbundle a hundred and then a ten). Talk through each trade and ask your child to write the 'because' sentence for one of them.

    Practice

    Your child solves 6 problems with drawings: 274 + 358 (632), 519 + 286 (805), 646 + 197 (843), 832 - 375 (457), 500 - 264 (236), 961 - 583 (378). They check 500 - 264 by adding 236 + 264 and drawing it. Support: build the first subtraction with straws before drawing. Stretch: solve 646 + 197 with compensation (646 + 200 - 3).

    Wrap-Up

    Ask, 'Which problem needed the most trades? How did you keep track?' Point out that neat drawings make trades easy to see.

    Shared Reading

    Read 'The Tiny Seed' by Eric Carle. As the seeds travel, have your child say what happens to each one and why (the seed that lands on ice cannot grow because it is too cold; the seed that lands in the desert is too hot). Ask how this story connects to 'From Seed to Plant' from Week 7.

    Mini-Lesson

    Teach that steps in a process are also connections: each step has to happen before the next. Build a chain for the tiny seed's year (autumn wind carries it, winter it rests, spring it sprouts, summer it blooms, autumn it makes new seeds). Note that this chain is a circle, and draw it that way.

    Independent Reading

    Your child reads a self-chosen nonfiction book for 12 minutes with the purpose 'find one chain of connected ideas.' They draw the chain on a sticky note with arrows and read it to you as sentences.

    Writing Workshop

    Editing day. Give your child a three-item checklist on an index card: every sentence starts with a capital, every sentence ends with a mark, and every word from the word wall is spelled right. Your child reads each page with a colored pencil, fixing as they go, and you check the last page together. Support: Edit one page together first, saying each rule aloud as you check it. Stretch: Replace two plain verbs with stronger ones (goes to zooms, eats to munches) and explain the shade of meaning.

    Word Study

    Multisyllable review from Week 9 using unit words. Divide and read: sunflower, butterfly, caterpillar, chrysalis, habitat, animal, seedling, blossom, pollen, nectar. Your child claps the syllables and names the type of the first syllable in five of the words (open, closed, or silent-e).

    Set the shoebox habitat from Week 9 and the seed comic from Week 10 side by side. Ask, 'What does the animal in your box eat? Where does that food come from? What might that animal carry away?'

    Deeper Investigation: Connection Walk

    Walk around the yard, block, or a park with a clipboard. Your child looks for three connections and sketches each with an arrow: an animal or insect near a plant it might eat (aphid on a leaf, squirrel by an acorn, bird at a berry bush), a seed that could travel (dandelion, maple, burr), and a shelter made from plants (nest, hole under a root, ant hill by grass). Support: Find one connection with adult hints. Stretch: Draw a chain of three links, such as sun to grass to rabbit.

    Data Discussion

    Ask, 'Which connection was easiest to find? Which was hardest? What would happen to the animal if that plant disappeared?' Record the last answer.

    I can add and subtract within 1000 and jump by 10s and 100s.

    Look: 256 + 378

    1. Ones: 6 + 8 = 14. Trade 10 ones for 1 ten. Write 4.
    2. Tens: 5 + 7 + 1 = 13. Trade 10 tens for 1 hundred. Write 3.
    3. Hundreds: 2 + 3 + 1 = 6. So 634.

    Solve with a drawing. Circle each trade.

    1. 365 + 486 = ____
    2. 728 + 195 = ____
    3. 613 − 287 = ____
    4. 400 − 158 = ____

    Number ladder. Solve in your head.

    1. Start at 587. Add 10: ____ Add 100: ____ Take away 10: ____ Add 10: ____

    Challenge

    • Check 400 − 158 = 242 by adding: 242 + 158 = ____

    I can show steps in a chain and fix capitals and end marks.

    Look: fix it

    1. Read: where do owls sleep
    2. Start with a capital: Where.
    3. It asks something, so end with ?: Where do owls sleep?

    Draw the life of a pumpkin as a circle. Use arrows.

    • seed
    • sprout
    • vine with flowers
    • pumpkin
    • new seeds inside
    1. My pumpkin circle
    2. Why is this chain a circle?

    Fix the capital and the end mark. Write the sentence correctly.

    1. the fox has a bushy tail
    2. does a bee make honey
    3. wow, that frog can jump far

    Challenge

    • Use a stronger verb: The rabbit goes into its hole.

    I can find connections between plants and animals outside.

    Go on a connection walk. Sketch each connection with an arrow.

    1. An animal near a plant it might eat
    2. A seed that could travel
    3. A shelter made from plants

    Think and write.

    1. What would happen to the animal if that plant disappeared?

    You need: a clipboard or a hard book to write on
