    Warm-Up

    Put 4 index cards on the table: 25, 25, 25, 25. Ask your child how many in all and how they know (100, counting by 25s or two 50s). Then swap in 10, 20, 30, 40 and ask for the total (100) and the fastest grouping (10 + 40 and 20 + 30).

    Mini-Lesson

    Write 18 + 32 + 27 + 13. Say, 'With four numbers, I hunt for partners.' Circle 18 + 32 = 50 and 27 + 13 = 40, then 50 + 40 = 90. Show the same problem in a column: ones 8 + 2 + 7 + 3 = 20, so write 0 and carry 2 tens; tens 1 + 3 + 2 + 1 + 2 = 9. Both ways land on 90.

    Practice

    Your child solves 24 + 16 + 35 + 15, 41 + 22 + 19 + 8, 33 + 27 + 12 + 18, and 15 + 15 + 15 + 15 (answers 90, 90, 90, 60), drawing an arc between the pair they add first. Then they build 33 + 27 + 12 + 18 with straws, bundling every ten loose straws.

    Wrap-Up

    Ask, 'What did you notice about the answers to the first three?' (all 90). Ask them to make their own four-number problem that also equals 90.

    Read-Aloud

    Read the back-matter pages of 'What Do You Do with a Tail Like This?' where each animal gets a short paragraph. Read three of the paragraphs (the elephant, the scorpion, the humpback whale). After each one, ask, 'What is this paragraph mostly about?' and have your child answer in one sentence.

    Mini-Lesson

    Teach the 'Topic in the First Sentence' clue: nonfiction paragraphs often tell their topic in the first line and then give details. Read the humpback whale paragraph again and have your child point to the sentence that names the topic and then count the detail sentences.

    Guided Reading

    Choose a nonfiction library book with clear paragraphs (any Gail Gibbons title or a National Geographic Kids Reader works). Your child reads one page, writes the main topic of that page on a sticky note, and then reads a second page and does the same. Compare: 'Are the two pages about the same big idea?'

    Writing Workshop

    Your child starts a new informational paragraph about an animal from the read-aloud, using the table drawing: topic sentence on top, then two facts and one definition as legs. For example, 'Skunks use their tails to warn enemies. A skunk lifts its tail before it sprays. Spray is a smelly liquid that keeps animals away.'

    Word Study

    Flash through yesterday's ten cards, then add today's Dolch words: does, don't, fast, first, found, gave, goes, green, made, many. Play Snap: lay cards face up, say a word, and your child slaps it and reads it. Point out that 'does' and 'goes' look alike but sound different.
