    Warm-Up

    Estimate first: for 298 + 405, ask, 'About how much? Is it more or less than 700?' Then solve (703). Do the same with 612 - 189 (about 400, exactly 423).

    Mini-Lesson

    Read aloud: 'A school library has 348 fiction books and 275 nonfiction books. How many books in all?' Draw a bar model, solve with a base-ten drawing (623). Then: 'The library lends out 156. How many stay on the shelves?' (467). Show the check: 467 + 156 should equal 623, and draw it to confirm.

    Practice

    Your child solves three problems with drawings and a check: 'A jar holds 425 beans, 180 are added, how many now?' (605); 'A road is 730 meters long, 465 are paved, how many meters are not paved?' (265); 'Two boxes hold 218 and 394 paper clips, how many total?' (612). Support: give a partly drawn base-ten picture for the first problem. Stretch: write your own problem with a three-digit answer that needs two regroupings.

    Read-Aloud

    Reread the section of 'Sharks' about shark senses. Cover each caption with a sticky note and have your child write a new caption for the photo, then compare with the author's. Talk about what a good caption does: names what is in the picture and adds one fact.

    Guided Reading

    Give your child a mini 'Scavenger Hunt' list for the 'Sharks' book: find a fact using the index, a word meaning using the glossary, a section using the table of contents, and a picture fact using a caption. Your child writes each fact and the feature used beside it.

    Writing Workshop

    Your child writes the Last box: how the story ended and one sentence about how they felt ('I felt proud when the seed finally sprouted.'). Then reread the whole narrative from the top and add one detail about what someone said or did.

    Phonics

    Teach the consonant-le ending, where the last syllable is a consonant plus 'le.' Read and divide before the consonant: table, little, puzzle, bubble, apple, turtle, middle, candle, purple, jungle. Have your child write three of them from dictation and clap the two syllables.

    I can solve story problems and check with the opposite operation.

    Look: check your answer

    1. Solve: 518 − 243 = 275.
    2. Check by adding back: 275 + 243 = 518.
    3. You got back to where you started, so the answer is right.

    Draw a bar model. Solve. Then check with the opposite operation.

    1. A farm picked 364 red apples and 258 green apples. How many apples in all?
    2. Mia's school has 512 library books. It lends out 247. How many are still on the shelves?
    3. A trail is 480 meters long. Omar has walked 195 meters. How many meters are left?
