Day 4 · Thursday

Objective: I can put needs first in a budget and explain the opportunity cost of my choices.

Standards: D2.Eco.1.3-5

Materials: Budget from Day 3, 1 index card, Colored pencils in green, blue and orange, Notebook, Pencil

1. Warm-Up · 5 min

   Spaced review from Week 24. Ask: "What is opportunity cost?" (The next best thing you give up when you make a choice.) Then ask the big question: "Should you buy candy before you pay for a school supply you need? Why?"

2. Mini-Lesson · 10–15 min

   Say: "A smart budget pays for needs first, then saving, then wants." Model with Priya in the notebook. Say: "Priya has $15. Her needs are a notebook for $3 and pencils for $2." Ask: "What do her needs cost?" ($5.) Say: "She saves $4." Write 15 - 5 - 4 = 6. Say: "She has $6 left for wants. She wants a slime kit for $8." Ask: "Can she buy it this week?" (No. $8 is more than $6.) Say: "She has two choices. She can buy stickers for $3, or keep the $3 to buy the kit sooner. She picks the stickers." Ask: "What is her opportunity cost?" (Getting the kit sooner. That was her next best choice.) Say: "Her choice is not wrong. Every choice has a benefit and a cost. A good planner knows both." Ask: "What is the benefit of her choice?" (She enjoys the stickers now.) If stuck, say: "Could she stay safe, healthy and ready for school without it? Then it is a want."

3. Activity / Source Work · 15–20 min

   Budget Fix-Up. Write these facts on the index card and read them aloud. "Diego has $20 this week. He must pay $6 for a water bottle for practice and $4 for a field-trip lunch. He plans to save $3. He wants a $9 model kit and a $5 comic." 1) In the notebook, draw a table with four columns: line, kind, amount, money left. 2) Your child writes the needs first and finds the money left. (20 - 6 - 4 = 10.) 3) Add the Save line. (10 - 3 = 7. He has $7 for wants.) 4) Ask: "Which want fits? What is your evidence?" (The comic. $5 is less than $7. The kit costs $9, which is too much.) 5) Your child decides what Diego should do. There are two good answers. Buy the comic and keep $2. Or buy nothing and add the $7 toward the kit. 6) Your child names the opportunity cost of that choice. 7) Color each line: green for needs, blue for save, orange for wants.

4. Notebook Entry · 10 min

   Your child reworks the Day 3 budget. First add one need: a $3 pencil pouch for school. Put it on the first line and make the plan fit $12 again. Label each line NEED, SAVE or WANT. Then finish the frame: "I chose ___, so I gave up ___." Sample: "I chose the toy car, so I gave up the trading cards."

5. Exit Ticket · 5 min

   Read the exit questions aloud. Your child solves question 1 on paper. Check the subtraction together. Praise plans that put needs first.

Homework: Your child asks a family member to name one need and one want in this week's shopping. Look for your child telling which one comes first, and why.

Objective: I can find an unknown side length when I know the perimeter.

Standards: 3.MD.D.8, 3.OA.D.8

Materials: String, 20 inches long, Ruler, Grid paper, Plain paper, Pencil

1. Warm-Up · 5 min

   Spaced review from Week 15 Day 2. Write 25 + n = 40. Your child finds n (n = 15). Then practice ÷2 and ÷4 facts with no clock. Ask 14 ÷ 2, 16 ÷ 2, 24 ÷ 4 and 32 ÷ 4 (7, 8, 6, 8).

2. Mini-Lesson · 10–15 min

   Say: "Today we know the perimeter, but one side is hiding." Show the 20-inch string. Say: "This string is the whole perimeter of a rectangle. The rectangle is 7 inches long. How wide is it?" Sketch a rectangle. Label the top and bottom 7 and each short side w. Say: "The letter w stands for the unknown width." Write 7 + 7 + w + w = 20. Ask: "How much do the two long sides use?" (14) Write 7 + 7 = 14. Ask: "How much string is left for the two short sides?" (6) Write 20 − 14 = 6. Say: "Two equal sides share 6 inches." Write 6 ÷ 2 = 3. Say: "So w = 3. The width is 3 inches." Check by adding: 7 + 3 + 7 + 3 = 20. With the ruler, draw that rectangle and lay the string around it. It fits. Now your child does more. Sketch a triangle with sides of 6 cm, 7 cm and n. Its perimeter is 18 cm. Your child writes 6 + 7 + n = 18 and solves. (6 + 7 = 13; 18 − 13 = 5; n = 5)

3. Guided Practice · 10–15 min

   Your child sketches each shape and labels every side, with a letter for the unknown. 1) A rectangle has perimeter 16 cm and length 6 cm. (6 + 6 = 12; 16 − 12 = 4; 4 ÷ 2 = 2 cm) 2) A square has a perimeter of 24 inches. Ask: "How many equal sides share 24?" (4) Your child finds one side. (24 ÷ 4 = 6 inches) 3) A four-sided polygon has sides of 5, 3, 4 and n feet. Its perimeter is 15 feet. (5 + 3 + 4 = 12; 15 − 12 = 3 feet). If stuck, say: "Label every side you know. Add them. How much is left for the hidden side or sides?"

4. Independent Practice · 15–20 min

   Your child sketches, writes an equation with a letter, solves and checks by adding. 1) A rectangle has perimeter 18 cm and length 8 cm. (8 + 8 = 16; 18 − 16 = 2; 2 ÷ 2 = 1 cm) 2) A rectangle has perimeter 36 meters and length 10 meters. (10 + 10 = 20; 36 − 20 = 16; 16 ÷ 2 = 8 meters) 3) A square has a perimeter of 32 inches. (32 ÷ 4 = 8 inches) 4) A square has a perimeter of 12 feet. (12 ÷ 4 = 3 feet) 5) A triangle has sides of 6 meters, 8 meters and n. Its perimeter is 21 meters. (6 + 8 = 14; 21 − 14 = 7 meters) 6) A rectangle has perimeter 18 units and length 5 units. Check on grid paper. (5 + 5 = 10; 18 − 10 = 8; 8 ÷ 2 = 4 units) 7) Mia marks a rectangle play space with 34 feet of rope. It is 12 feet long. How wide is it? (12 + 12 = 24; 34 − 24 = 10; 10 ÷ 2 = 5 feet) 8) A five-sided flower bed has a perimeter of 25 meters. Four sides are 4, 6, 5 and 3 meters. How long is the fifth side? (4 + 6 + 5 + 3 = 18; 25 − 18 = 7 meters)

5. Exit Ticket · 5 min

   Read each question aloud; your child sketches, labels and shows each step.

Fact fluency: ÷2 and ÷4 facts

Homework: Solve and check by adding. A rectangle has perimeter 20 inches and length 6 inches. A square has a perimeter of 16 cm. Answers: the width is 4 inches; each side is 4 cm.

Objective: I can write a conclusion that sums up what I learned.

Standards: W.3.2.D, W.3.5

Materials: Writer's notebook, Report draft so far, Highlighter, Colored pencil

1. Warm-Up · 5 min

   Word study, Unit 5 review in meaning. Ask: "What is a station?" (A place where trains or buses stop.) "What does vision mean?" (The power to see.) "Which two words make we'll?" (we will) Say: "Use too in a sentence where it means also." (Sample: "I want to come too.") Spaced review from Week 29 Day 1. Ask: "Retell how bees make honey in three sentences." (Sample: Bees sip nectar. House bees dry it in wax cells. Then they seal the honey.)

2. Mini-Lesson · 10–15 min

   Say: "A conclusion wraps up the report. It has three parts. Restate the topic in new words. Sum up the biggest findings. End with something that sticks, like a surprise or a question." Read this model aloud. "A Report Conclusion. Honeybees are tiny, but together they do an enormous job. They gather nectar, change it inside the hive, and dry it until it becomes honey. What surprised me most is that one bee makes only about one-twelfth of a teaspoon in her whole life. I still wonder how bees tell each other where the best flowers are." Think aloud: "Sentence one restates the topic. My introduction said the report would explain how honeybees make honey. Here I say they do an enormous job. Same idea, new words. Sentence two sums up three findings in one breath. Sentences three and four end with a surprise and a question." Your child highlights the three parts. Say: "A conclusion adds no brand-new facts. New facts belong in the body."

3. Guided Practice · 10–15 min

   1) Ask: "Which sentence sums up the findings? How many findings does it name?" (The second. It names three.) 2) Ask: "How does the model end?" (With a surprise, then a question the writer still has.) 3) Ask: "Would 'Bees have five eyes' belong in this conclusion?" (No. It is a brand-new fact.) 4) Together, write the first sentence of your child's conclusion. Compare it with the introduction. Here is a sample pair. Introduction: "This report will explain how sea otters stay warm." Conclusion: "Sea otters have smart tricks for beating the cold sea." Ask: "Is your sentence the same idea in new words?" (Yes) If stuck, say: "Finish this: Through my research I learned that ___."

4. Independent Practice · 15–20 min

   1) Your child writes a conclusion of 4 or 5 sentences with the three parts. Frame: "___ are ___. I learned that ___. What surprised me most was ___. I still wonder ___." 2) Your child rereads the whole draft aloud, from title to conclusion. 3) Your child stars one spot where something is missing or confusing, to fix next week. 4) In colored pencil, your child ticks this checklist: topic restated in new words; biggest findings summed up. Also: a surprise or question at the end; no new facts.

5. Exit Ticket · 5 min

   Ask the three questions. Your child holds the draft while answering.

Homework: Read your full draft aloud to a family member, from start to finish. Ask them to name one fact they learned. Look for a smooth voice and pauses at periods. About 15 minutes.

I can write a conclusion that sums up what I learned.

Show answers

Look: three parts of a conclusion

1. Restate the topic in new words.
2. Sum up the biggest findings.
3. End with a surprise or a question you still have.

A Conclusion

Sea turtles are amazing ocean travelers. They swim thousands of miles and still find their way back to the beach where they hatched. The most surprising thing I learned is that they may use Earth's magnetic pull like a map. I still wonder how a baby turtle knows which way the ocean is.

Use the conclusion above.

1. 1.

   Underline the sentence that restates the topic.

2. 2.

   What question does the writer still have?
3. 3.

   Intro: 'This report will explain how dogs help people.' Restate it in new words for a conclusion.
4. 4.

   Should a conclusion add brand-new facts?

   ○ Yes○ No
5. 5.

Challenge: Write the last sentence of your own conclusion: a surprise or a question.

Objective: I can explain how differences in traits can help some individuals survive, find mates and have offspring.

Standards: 3-LS4-2

Materials: Tweezers, a spring clothespin and a spoon (model beaks), 30 grains of dry rice and 30 dried beans, 2 plates and 1 cup, Science notebook and pencil

1. Day 149 — Why Variation Matters — Wonder Warm-Up · 5 min

   Spaced review from Week 11. Ask: "What is an adaptation?" (A body feature or behavior that helps a living thing survive where it lives.) Now the wonder. Ask: "Suppose every tree in a forest were exactly alike, and a new disease came. What might happen?" (All might get sick. With variation, some might survive.)

2. Mini-Lesson · 10–15 min

   Say: "Variation can give some individuals an advantage. An advantage is a better chance to survive, find a mate or have offspring." Staying safe. Say: "Mice of one kind live on pale sand. Some have paler fur. Owls spot the darker mice more easily." Getting food. Say: "Some birds of one kind have slightly longer beaks. They reach insects deeper in bark." Finding a mate. Say: "A mate is a partner for having offspring. Male elk with larger antlers often win pushing contests and find mates." Say: "An advantage depends on the place. Pale fur helps on pale sand, not on dark rock." Lay one rice grain on a white notebook page and one on a dark surface. Ask which is easier to spot. Ask: "Pale and dark mice live on dark rock. Which has the advantage?" (The dark mice.) "Did a mouse choose its fur color?" (No. It was inherited.) If stuck, say: "Which one is more likely to eat, hide or win here?"

3. Investigation / Hands-On · 15–20 min

   Beak Variation Model. Safety: hold the tweezers with the points down, and keep rice and beans away from very young children. Say: "These three tools are birds of one kind whose beaks vary." 1) Put 30 rice grains on one plate and 30 beans on the other. 2) Rule: one hand, one piece each trip, dropped into the cup. 3) Your child uses the tweezers on rice while you count slowly to 20. Count the rice in the cup, record it and return it. 4) Repeat with the clothespin, then the spoon. 5) Repeat all three beaks with beans. Use a table with three columns: Beak, Rice in cup, Beans in cup. Change only the beak. Keep the same food, 30 pieces, the count to 20 and the rule. Often the tweezers gather the most rice, and another beak gathers the most beans. Say: "Real results vary. Look for the pattern." Ask: "If only beans grew on an island, which bird has the advantage?" One limit: real beaks of one species differ far less than these tools.

4. Science Notebook Entry · 10 min

   Your child copies the results table. Then they write a claim: "The ___ beak had an advantage with ___ because ___." They add one real example of a helpful variation. Sample: "The tweezers beak had an advantage with rice because it gathered 9 grains and the spoon gathered 4."

5. Wrap-Up & Exit Ticket · 5 min

   Read the three exit questions aloud; your child uses the results table for question 3. Praise answers that give numbers as evidence.

Homework: Explain the beak model to a family member. Test which beak is best for picking up small dry pasta. Look for: a fair test with the same count each time.
