    Week 11, Thursday: Apply strategy explanations · Create an image that clarifies their own writing

    Day 54 · 3 lessons · 140 min

    Math

    Students apply strategy explanations by teaching a strategy to someone else and critiquing a sample explanation (2.NBT.B.9, 2.OA.A.1).

    Standards Addressed

    Activities

    10 min

    Warm-Up

    Find the mistake: show this work on paper, 45 + 37 = 72 with the ones written as 5 + 7 = 12 but no carried ten. Your child finds the error, fixes it (82), and explains what the missing ten stands for.

    Mini-Lesson

    Read a word problem: 'A farmer has 63 chickens and buys 28 more. How many chickens now?' Show a pretend student answer: 'I did 60 + 20 = 80 and 3 + 8 = 11, so 91.' Ask your child to judge it: Is it correct (yes), which strategy is it (decomposing), and what could make the explanation clearer (say that 80 + 11 = 91). Repeat with a compensation answer for 'A shop had 82 kites and sold 39' (43).

    Practice

    Teaching time: your child picks one strategy (make a ten, number line, decompose, compensation, or base-ten drawing) and teaches it to you or a sibling using 57 + 36 (93) with straws or a drawing, then answers your question, 'Why does that step work?' Then they write a 3 to 4 sentence explanation of the same strategy on an index card.

    Wrap-Up

    Ask, 'What was hard about explaining instead of just solving?' Post the index card on the fridge as a reference for Friday.

    English Language Arts

    Students create an image that clarifies their own writing and draft the third All About section with a fact from experience (RI.2.7, W.2.8).

    Read-Aloud

    Reread the beekeeper pages of 'The Honey Makers.' Cover the pictures with paper and read the words only, having your child list every question that comes up ('What does a smoker look like?'). Uncover the pictures and count how many questions the pictures answered.

    Mini-Lesson

    Teach the three rules of a helpful diagram: draw it big, label the important parts with straight lines, and give it a caption that says what it is. Model on the board with a bee: label head, thorax, abdomen, wings, and stinger, then write the caption 'A worker bee has three body parts.'

    Guided Reading

    Your child rereads the observation page in the research folder and the science notebook drawings, then finds a page in one of the research sources with a picture of the same thing. Write a sentence comparing them: 'My drawing shows ______ and the book's picture also shows ______.'

    Writing Workshop

    Your child drafts the third section, including one fact that came from their own observation ('I saw the bean's root grow before the leaves'). Then draw and label the planned diagram for one section, with a caption under it, following the three rules.

    Word Study

    Teach the three sounds of the -ed ending and read these words in a smooth voice: jumped, buzzed, landed, hopped, filled, wanted, walked, played, needed, watched. Sort them by whether -ed says /t/, /d/, or /id/, then read a page from 'The Honey Makers' and hunt for any -ed words.

    Social Studies

    Students classify resources as renewable or nonrenewable and plan one way their family can conserve a natural resource (D2.Geo.5.K-2).

    Standards Addressed

    Activities

    10 min

    Review and Extend

    Hold up an apple and a stone. Say, 'If I eat this apple, the tree grows more. If I use up this stone, no new one grows.' Sort Tuesday's resource list into Can Grow Back (trees, plants, animals, sunlight) and Cannot Grow Back Quickly (oil, metal, rock). Ask, 'Which list should we be most careful with?' Support: Sort four items with picture cards. Stretch: Explain why water belongs on both lists, since it can be cleaned but also can run out in a drought.

    Project Work: Family Conservation Plan

    Your child chooses one resource to protect this week: water (shorter showers, turn off the tap while brushing), trees (use both sides of paper), or electricity (lights off when leaving a room). Make a poster with the rule, a picture, and a seven-day tally chart to track each time the family follows it.

    Today's Practice

    One page for your child for each lesson. Answers are for grown-ups.

    Math practice · Week 11 · Thursday

    I can check someone's work and explain a strategy.

    Look: Lin says 38 + 45 = 73

    1. Check the ones: 8 + 5 = 13.
    2. 13 is 1 ten and 3 ones. Lin forgot the ten.
    3. Tens: 3 + 4 + 1 = 8. The right answer is 83.

    Be the teacher. Is the work right? If not, fix it.

    1. Sam added 56 and 28 and got 74. He wrote 6 + 8 = 14. What did he forget?
    2. Bo did 72 − 45 like this: 72 − 50 = 22, then 22 − 5 = 17. Is he right?
    3. A farmer has 47 hens and gets 36 more. Rosa did 40 + 30 = 70 and 7 + 6 = 13, so 83. Is she right? Which strategy?

    Teach a strategy.

    1. Solve 65 + 27 = ____ your way. Write how and why it works.

    I can make a diagram for my writing and read -ed words.

    Look: A helpful diagram

    1. Draw it big.
    2. Label the important parts with straight lines.
    3. Write a caption that says what it is.

    Draw a diagram for one section of your All About book.

    1. My diagram
    2. My caption:

    Read each word. What sound does -ed make? Circle it.

    1. kicked/t//d//id/
    2. rained/t//d//id/
    3. painted/t//d//id/
