    Math

    Students will apply odd and even reasoning to real situations, such as sharing fairly between two people and predicting whether a sum will be odd or even (2.OA.C.3).

    1. 6 + 5 = ? Facts to 20
    2. There are 40 cars in a lot. 12 leave, then 18 more come. How many cars now? Week 16
    3. 8 + 7 = ? and 15 − 8 = ? Week 15

    Activities

    10 min

    Warm-Up

    Fair-share puzzles: 'Two friends want to split 16 crackers evenly. Can they?' (yes, 8 each). '17 crackers?' (no, one left over). '20 grapes?' (yes, 10 each). Use real crackers or beans.

    15 min

    Mini-Lesson

    Investigate sums. Add two even numbers with beans (6 + 4 = 10, pairs stay paired, even). Add two odds (5 + 3 = 8, the two leftovers pair up, even). Add an even and an odd (6 + 3 = 9, one leftover stays, odd). Make a three-row chart: even + even = even, odd + odd = even, even + odd = odd. Test each rule with one more example your child picks.

    15 min

    Practice

    Before solving, your child predicts odd or even for each sum, then solves and checks: 12 + 8, 7 + 9, 15 + 4, 11 + 11, 6 + 13, 18 + 2. Then a story: 'Tara and Jo found 23 shells. Can they each get the same number with none left over? Draw or explain.' (no, 23 is odd, one left).

    5 min

    Wrap-Up

    Ask, 'Why does odd plus odd make even?' Have your child show it with two leftover beans joining into a pair.

    Shared Reading

    Reread the pellet page in 'Owls' by Gail Gibbons and the matching page in Laura Marsh's book. Ask your child to say the same important point in their own words once for each book and decide which author explained it more clearly.

    Mini-Lesson

    Teach recording basics on a phone or tablet: hold it still, wait two seconds before speaking, read a little slower than feels normal, and stop if you stumble and start the sentence again. Record a ten-second test and play it back to hear how it sounds.

    Independent Reading

    Your child rehearses their 'Owl Moon' page and Owl Fact Report aloud three times alone, then once for you. Ask them to make the fact report sound like a news reporter and the story page sound like a whisper in the snow.

    Writing Workshop

    Final edit of the Owl Fact Report: check capitals, periods, and the spelling of owl, feathers, pellet, and prey against the books. Your child then makes a title card for the recording: 'All About Owls by ____'.

    Phonics: Roots

    Teach that a root word is the base that prefixes and suffixes stick to. Build word families on paper: hunt (hunter, hunted, hunting), help (helper, helpful, helpless, unhelpful), play (player, playful, replay, playing), care (careful, careless, caring). Your child reads each family and circles the root.

    Review and Extend

    Point to each card on the calendar strip and have your child say who is remembered. Then read 'The Wall' by Eve Bunting and ask gently: 'Why did the boy and his father travel to the wall? Why do people leave flags and letters there?' Explain the difference: Memorial Day remembers those who died serving, Veterans Day thanks everyone who served.

    Project Work

    Add a 'Days We Remember' section to the poster with three holidays your child chooses, each with a date, a picture, and the sentence 'On this day we remember ___.' Then interview a family member by phone or in person: 'How did your family celebrate a national holiday when you were a kid?' and write two details next to the matching holiday. Support: provide the sentence frame and pre-written date cards. Stretch: ask your child to add a holiday from another country a friend or relative celebrates and explain who it remembers.

    Share Progress

    Your child presents the three holidays and one thing learned from the interview. Ask: 'Why does a whole country need to remember together instead of each family on its own?'

    I can tell if a sum will be odd or even and share fairly.

    Look: The rules

    1. even + even = even
    2. odd + odd = even (the two leftovers make a pair)
    3. even + odd = odd (one leftover stays)

    Guess odd or even first. Then solve and check.

    1. 14 + 6 = ____
    2. 9 + 5 = ____
    3. 8 + 7 = ____
    4. 13 + 13 = ____
    5. 10 + 9 = ____

    Solve. Draw or explain.
