    Warm-Up

    Spiral from Week 15: 1-minute burst of 15 facts within 20, then ask your child to name the strategy for 9 + 7 and 15 - 6. Say, 'Fast facts are the tools. Today we build with them.'

    15 min

    Mini-Lesson

    Read: 'Nora had 45 stickers. She gave 18 to her brother. Then she bought 25 more. How many stickers does Nora have now?' Model step one as a take-from bar (45 - 18 = 27) and step two as an add-to bar (27 + 25 = 52). Write both equations numbered. Say, 'One step subtracts, one step adds. Read carefully so you know which is which.'

    15 min

    Practice

    Your child solves: 'A pet store had 36 fish. It sold 19 and then got 30 new fish. How many fish now?' (36 - 19 = 17, 17 + 30 = 47). Then: 'Theo had 28 pennies. He found 15 more and then spent 20. How many pennies now?' (28 + 15 = 43, 43 - 20 = 23). Use pennies to act out the second problem and confirm.

    5 min

    Wrap-Up

    Ask, 'How did you decide whether each step was adding or subtracting?' Listen for 'gave, sold, spent mean subtract; bought, found, got mean add.'

    Read-Aloud

    Read 'I Wanna Iguana' by Karen Kaufman Orloff, doing Alex's letters in an eager voice and Mom's in a calm one. Remind your child that last week they gave reasons about sharks; this week they will study how a writer chooses reasons that actually work. Ask: 'Which of Alex's reasons would convince you?'

    Mini-Lesson

    Make a T-chart labeled Alex's Reasons and Mom's Answers. Fill in three pairs from the letters (the iguana is quiet; it will grow six feet long). Say: 'A reason is why you think something, and a strong reason answers the other person's worry.'

    Guided Reading

    Reread three letters with your child reading Alex's parts. When they meet a tricky word, model the context clue strategy: read the sentence before and after, look at the picture, and try a word that makes sense. Note any words they solved on a Context Clue List.

    Writing Workshop

    Your child chooses something they want to persuade you about (a later bedtime, a pet, a trip to the park) and writes a letter opening like Alex: 'Dear Mom, I think ____ because ____.' Keep it in the Writing Folder to build all week.

    Phonics: Context Clues

    Write six sentences with a blank and a word bank of adorable, responsible, lonely, mature, compromise, tarantula (for example, 'The kitten was so ____ that everyone wanted to hold it'). Your child reads each sentence, picks the word that fits, and explains the clue that helped.

    Science Question of the Week

    Ask: 'Will our plan work the way we drew it?' Reread last Friday's worry from the notebook. Say: 'Engineers expect surprises; that is why they build a prototype before the real thing.'

    20 min

    Investigation

    Build the crayon holder from the plan using the materials kit, following the step list with your child doing the cutting and taping and you assisting only where asked. Every time you have to change something from the drawing, put a small star on the plan and write what you did instead ('lid too small, used cereal-box bottom'). Stop at 18 minutes even if unfinished and note where you are.

    Wrap-Up

    Count the stars on the plan. Ask: 'Which change was the most surprising?' Put the prototype somewhere safe and write 'Test on Wednesday' at the top of a fresh notebook page.

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

    Math practice · Week 16 · Monday

    I can solve a two-step story that adds and subtracts.

    Look: Ben had 42 cards. He gave 15 away. Then he got 20 more.

    1. Step 1 (take away): 42 − 15 = 27.
    2. Step 2 (add to): 27 + 20 = 47. Ben has 47 cards.
    3. Gave means subtract. Got means add.

    Draw a bar for each step. Write two numbered equations.

    1. A shop had 48 kites. It sold 29. Then it got 25 new kites. How many kites now?
    2. Leah had 36 pennies. She found 17 more. Then she spent 25. How many pennies now?
    3. A class had 30 crayons. They bought 24 more. Then they lost 9. How many crayons now?

    Challenge

    • Circle the words that told you to add or subtract.
