🔭 Play with your child: Root Lens

The day, step by step

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

   1. Question of the day: What is the most dangerous thing in your kitchen, and how do you stay safe around it? Students answer, then share one rule they follow to stay safe in a kitchen.
   2. Current events: two-sentence summary from a volunteer.
   3. Check yesterday's exit ticket: QR = 16.

2. 15–20 min Vocabulary and word study L.9-10.4a

   1. Find two spect or vis words in today's pages (or use these model sentences): The jeweler inspected the case. Her hardship became visible in her hands.
   2. For each, underline the clue words in the sentence and write a guessed meaning before checking a dictionary.
   3. Write one new sentence where the context makes the word evident without a definition.

3. 30–40 min Literature and texts RL.9-10.3

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

   1. Read the search for the necklace, the purchase of a replacement for 36,000 francs and the ten years of hard work that follow.
   2. Before-and-after chart: Mathilde's home, work, appearance and attitude at the start versus after ten years. Cite one detail for each row.
   3. Discuss: does Mathilde change for the better, the worse, or both? Students must use the word because in their answer.
   4. Reading log: copy the sentence that best shows how she has changed and explain why you chose it.

4. 40–50 min Geometry HSG-GPE.B.6

   1. The midpoint of two numbers on a line is their average. Midpoint of -3 and 11: (-3 + 11) / 2 = 8 / 2 = 4.
   2. Distance on a number line is the absolute value of the difference. Distance from -8 to 5: |5 - (-8)| = 13.
   3. Practice: midpoint of 6 and 20 (13); midpoint of -10 and -2 (-6); distance from -7 to -1 (6).
   4. Reverse problem: M is the midpoint of AB, A is at 2 and M is at 9. Where is B? (16, because 9 - 2 = 7 and 9 + 7 = 16.)
   5. Exit ticket: find the midpoint of -15 and 3 and the distance between them. (Midpoint -6, distance 18.)

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

   1. Steps of the scientific method: question, background, hypothesis, experiment, data, conclusion.
   2. Our question: does sugar dissolve faster in hot tap water or cold tap water? Name the variables: independent (water temperature), dependent (time to dissolve), controlled (amount of sugar, amount of water, stirring, cup size).
   3. Each student writes an if-then-because hypothesis, for example: If the water is hotter, then the sugar will dissolve faster, because the water particles move faster.
   4. Plan the procedure for Friday: 1 teaspoon of sugar in 1 cup of water, stir 5 times every 10 seconds, three trials for each temperature. Use hot tap water only, never boiling.

6. 25–35 min Writing W.9-10.9

   1. Model a signal phrase: Maupassant writes that... / As the narrator explains...
   2. MLA citation for a short story: the author's last name and the page in parentheses, for example (Maupassant 4). The period goes after the parentheses.
   3. Students introduce one quotation about the ten years of work with a signal phrase and a citation.

7. 25–35 min Independent practice and projects

   1. Make a before-and-after sketch of Mathilde with one quotation under each picture.
   2. Solve: midpoint of -9 and 17, and distance from -4 to 12. (4; 16)
   3. Draw the data table for Friday's dissolving test with columns for trial, temperature and time.
   4. Find two more spect or vis words in a newspaper or website and define them from context.

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

   Device time (15 min): play Root Lens on the Student games page.

   Today’s game: Root Lens

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

   1. Name one way Mathilde changes and one way she stays the same.
   2. How do you find the midpoint of two numbers?
   3. What are the independent and dependent variables in our sugar test?

Short day? Keep the reading, the midpoint examples and the variables; do the full hypothesis tomorrow.
