📏 Play with your child: Segment Sense

The day, step by step

1. 10–15 min Morning meeting and current events SL.9-10.1

   1. Question of the day: What makes evidence convincing to you? Students rank three kinds of evidence: a statistic, an eyewitness and a photo, and explain.
   2. Current events: two-sentence summary from a volunteer.
   3. Preview today: checks in reading, word study and math, plus our first real lab.

2. 15–20 min Vocabulary and word study L.9-10.2c, L.9-10.4b

   1. Spelling and roots check: spectator, inspect, perspective, retrospective, introspective, spectacle, visible, vision, revise, evident, video, provide.
   2. Bonus: write the root in each word and its meaning.
   3. Write one sentence using perspective about The Necklace. Partners check each other with the answer key.

3. 30–40 min Literature and texts RL.9-10.1, RL.9-10.4

   The Necklace by Guy de Maupassant (public domain; any translation)

   1. Reading check: a short unseen passage (one page of a story the class has not read) with three questions.
   2. Question 1 (meaning): what is the passage mostly about? Question 2 (craft): what is the effect of one word or image the author chose? Question 3 (claim): make a claim about a character and cite one detail.
   3. Go over the answers together. Students score themselves on the claim using claim, evidence, explanation.

4. 40–50 min Geometry HSG-CO.D.12

   1. Copy a segment: draw AB, draw a ray from C, open the compass to AB and mark D on the ray so CD = AB.
   2. Bisect a segment: with the compass open more than half of AB, draw arcs from A and B above and below. The line through the two crossings is the perpendicular bisector; it meets AB at the midpoint.
   3. Measure to check: if AB is 8 cm, each half should be 4 cm.
   4. Segment check (8 items): name a ray, a segment and a plane; two segment addition problems; a number line midpoint and distance; a coordinate midpoint and a coordinate distance.

5. 30–40 min Chemistry HS-PS1-3, HS-ETS1-3

   1. Goggles on. Add 1 cup of hot tap water to one cup and 1 cup of cold tap water to the other. Never use boiling water.
   2. Add 1 teaspoon of sugar to each, stir 5 times every 10 seconds and time until no crystals show. Do three trials per temperature.
   3. Sample results: hot 32, 35, 30 seconds (average 32.3); cold 118, 125, 121 seconds (average 121.3). Students compute their own averages.
   4. Write a claim-evidence-reasoning conclusion: claim (sugar dissolves faster in hot water), evidence (the averages), reasoning (faster-moving water particles pull sugar particles apart sooner).

6. 25–35 min Writing W.9-10.5

   1. Partner checklist: Is the claim arguable? Is the quotation introduced and cited? Do the explanation sentences say how, not just that?
   2. Each student revises one sentence of explanation and one transition.
   3. File the revised paragraph in the literature tab of the portfolio.

7. 25–35 min Independent practice and projects

   1. Bisect a 10 cm segment and check each half is 5 cm.
   2. Graph your class's dissolving data as a bar graph of average times.
   3. Fix any missed words from the spelling check with a new sentence for each.
   4. Write a reading log entry about the whole story: one quotation and one question.

   Projects: set up the reading log and the writing portfolio; they travel with you all year.

   Device time (15 min): play Segment Sense on the Student games page.

   Today’s game: Segment Sense

8. 5–10 min Closing reflection SL.9-10.1

   1. Which check today felt strongest for you, and which needs work?
   2. What did the dissolving data show, and how confident are you in it?
   3. What is one thing you will do differently next week?

Short day? Keep the dissolving lab and the segment check; move the reading check to Monday if needed.
