    Warm-Up

    Three-way review. Show 14 beans: 'Prove it is even by pairing.' Show the number 58 written: 'Prove it is even by the ones digit.' Say 18: 'Prove it is even with a doubles equation.' Repeat with 9, 41, and 13 as odd examples.

    15 min

    Mini-Lesson

    Hunt for odd and even around the house together: count the windows in one room, the spoons in the drawer, the stairs, the buttons on a shirt. For each, your child records the count, writes E or O, and gives one proof (pairs, ones digit, or double). Aim for six items.

    15 min

    Weekly Assessment

    Part 1: with beans, pair up 13 and 16 and label each odd or even. Part 2: circle the even numbers in this list and explain the rule: 27, 34, 50, 61, 78, 85, 92, 19. Part 3: write equal-addend equations for 12, 18, and 20, and write 15 as a double plus one. Part 4: 'Two friends share 19 stickers. Will there be one left over? Explain.' Score each part for the method used and the answer.

    5 min

    Wrap-Up

    Reflect: 'Last week we solved two-step stories; this week we found a pattern that never breaks. Which proof for odd or even is your favorite?' Preview next week: rows and columns and repeated addition.

    Reading Celebration

    Owl Prowl: turn off the lights, hand your child a flashlight, and have them read the last page of 'Owl Moon' to the family in their whisper voice. Then everyone shares the one owl fact they will remember longest.

    Reading Assessment

    With the Important Points chart put away, your child writes two important points that both owl books make and one point that only one book makes, naming which book. This is the week's assessment.

    Publishing and Author's Chair

    Record the final audio: the intro sentence, the Owl Fact Report, and the 'Owl Moon' page. Play it back for the family as the Author's Chair, and save it with the date so you can compare it with a recording later in the year.

    Independent Reading

    Drawing Conclusions

    Read the Comparison Table together and write a recommendation in the notebook: 'We recommend Design ___ because it won ___ rows, especially ___.' Then sketch a Design C that borrows the best part of the loser (for example A's tall lip on B's heavy base).

    Extension or Art Connection

    Turn the Comparison Table into a picture graph: one crayon drawing for each crayon that escaped in the tilt test, for A and for B, side by side, so the difference is easy to see. Add a title and a key, and glue it into the notebook. Ask: 'Does the graph tell the same story as the table?'

    Week Reflection

    Ask: 'What did you learn from the design that lost?' and 'What would you tell a friend who wants to build one?' Next week is the showcase, so decide together who will be invited.
