    Warm-Up

    Say a number and have your child say 10 less and 100 less: 356, 720, 405, 190, 1000. Then ask: 'Yesterday we added in two steps. What might a two-step problem look like if something is taken away?'

    Mini-Lesson

    Revisit subtraction and comparison problems (first taught Week 14). Pose: 'Ava has 52 marbles. She gives 14 to her brother and loses 8 in the yard. How many are left?' Draw a bar of 52, cut off 14, then cut off 8, and write 52 - 14 - 8 = 30. Then a comparison: 'Sam has 36 cards. Jo has 19 fewer. How many do they have together?' Show two bars (36 and 17) and the two steps: 36 - 19 = 17, then 36 + 17 = 53.

    Practice

    Explore with counters: your child builds each story with beans before writing an equation. 'A baker made 60 muffins, sold 28 in the morning and 17 in the afternoon. How many left?' (15). 'Nina is 43 inches tall. Her sister is 9 inches shorter. What is their total height in inches?' (77). 'A book has 85 pages. Ben read 39 on Monday and 26 on Tuesday. How many pages remain?' (20). Support: give the bar model outline pre-drawn and let your child fill in the numbers. Stretch: write your own two-step story about the picnic table setup for a grown-up to solve.

    Wrap-Up

    Ask: 'What word in a problem tells you to subtract? What word tells you to compare?' List the words (left, fewer, shorter, remain, how many more) on an index card and clip it in the portfolio folder.

    Read-Aloud

    Read 'The Garden' from Frog and Toad Together. Say: 'In Week 2 we learned to watch how a character acts when something goes wrong. Watch what Toad does when the seeds do not come up.' Pause each time Toad tries something new (shouting, candles, songs, poems) and have your child say what Toad is feeling.

    Mini-Lesson

    Draw a three-column chart: Event, What Toad Does, What Toad Feels. Fill in the first row together (the seeds do not grow; Toad shouts at them; Toad is worried and impatient). Say: 'A character's actions are clues to their feelings, and feelings change as the story goes on.'

    Independent Reading

    Your child rereads 'The Garden' and fills in two more rows of the chart on their own, then reads a book of their choice for the remaining time. Ask at the end: 'How did Toad feel at the very end, and how do you know?'

    Writing Workshop

    Genre review, day two: opinion (first taught in Week 4 and Week 13). Your child writes 'Frog is a good friend because...' and gives two reasons from 'The Garden' or 'A List', using the linking words because and also. Then they add one more sentence to yesterday's small-moment story.

    Phonics

    Silent e and r-controlled vowel review from Week 4. Sort these word cards into two piles: cake, bird, hope, farm, mule, corn, time, hurt. Your child reads each pile aloud and tells which rule it follows. Support: read each word together first, then let your child sort. Stretch: add a third pile for words with both patterns (care, fire, store).
