Five warm-ups for grades 6–8. Each takes three to five minutes. Answers and teacher notes are in the collapsed box under each prompt.
ELA
Each line below is missing its dialogue punctuation. Rewrite each one with quotation marks, commas, end marks, and capital letters where they belong. Then write two lines of your own conversation between two characters who disagree about what to eat for dinner.
- where are you going asked Mom
- I think said Leo that we missed the bus
- Nina shouted watch out for the puddle
- the movie starts at six said Dad we should leave soon
Answer and teacher notes
1. “Where are you going?” asked Mom.
2. “I think,” said Leo, “that we missed the bus.”
3. Nina shouted, “Watch out for the puddle!”
4. “The movie starts at six,” said Dad. “We should leave soon.”
Your own lines: Answers will vary. Sample: “Let’s have tacos,” said Maya. “We had tacos yesterday!” Ben groaned.
Common mistake on #2: capitalizing “that.” The sentence is interrupted, not finished, so the second part stays lowercase. Compare it with #4, where each part is a complete sentence, so a period comes after “Dad” and “We” gets a capital. Also point out that in #1, the question mark goes inside the quotation marks and replaces the comma. Reminder: start a new paragraph each time the speaker changes. Extension: replace “said” in one line with a stronger verb and explain how it changes the mood.
Math
Two bike shops rent bikes by the hour. Shop A charges a $12 fee plus $8 per hour. Shop B charges a $30 fee plus $5 per hour. (These prices are made up for practice.)
- Write an equation for the cost C at each shop after h hours.
- A rider paid $44 at Shop A. Solve to find how many hours the rider had the bike.
- After how many hours do the two shops cost the same? What is that cost?
- Which shop is cheaper for an 8-hour ride? By how much?
Answer and teacher notes
1. Shop A: C = 8h + 12. Shop B: C = 5h + 30.
2. 8h + 12 = 44, so 8h = 32, and h = 4 hours.
3. 8h + 12 = 5h + 30, so 3h = 18, and h = 6 hours. Cost: 8(6) + 12 = $60. Check: 5(6) + 30 = 60. ✓
4. Shop A: 8(8) + 12 = $76. Shop B: 5(8) + 30 = $70. Shop B is cheaper by $6.
Check on #2: 8(4) + 12 = 44. ✓ Common mistake: dividing before subtracting. Undo the fee first, then the hourly rate. The lower hourly rate wins on long rides, and the lower fee wins on short ones, which is why the shops switch places at 6 hours. Extension: a rider has $70 to spend at Shop A. What is the greatest number of whole hours the rider can rent? (8h + 12 ≤ 70, so h ≤ 7.25. The answer is 7 hours.)
Science
Ancient Egyptian embalmers covered bodies with natron, a natural salt that draws out water, because a fully dried body would not easily decay. The Smithsonian says the whole mummification process took seventy days. People use the same idea today. Raisins, jerky, and dried herbs last far longer than fresh foods. Decomposers are living things, such as bacteria and molds, that break down dead material. (a) What do decomposers need that drying takes away? (b) A fresh apple slice and a dried apple slice sit on a plate for a week. Which one do you predict will grow mold first? Why? (c) Egypt has a very dry desert climate. How might that have helped preserve things? (d) Name one other food that is kept from spoiling by drying or salting.
Answer and teacher notes
(a) Water. Decomposers need moisture to live and grow. (b) The fresh slice, because it still holds water that mold can use. (c) Dry air holds less moisture, so things dry out faster and decomposers have less water to work with. (d) Answers will vary: beef jerky, salted fish, dried fruit, dried herbs.
Keep the focus on the science of drying. If you want more background, the Smithsonian page includes details about the steps of mummification, so preview it before sharing with students. Common mistake: thinking salt or drying kills everything. Removing moisture lowers the chance that bacteria or mold will grow, but dried food still needs safe storage. North Carolina State Extension notes that moisture is what creates a breeding ground for bacteria and mold. Extension: design a fair test using apple slices, with and without salt. What would you keep the same? What would you measure?

Social Studies
On November 4, 1922, in Egypt’s Valley of the Kings, a team led by British archaeologist Howard Carter found a step cut into the ground. Live Science reports that an Egyptian worker found the step, and some accounts credit a water boy named Hussein Abd el-Rassul. The steps lay about 13 feet below the tomb of a later pharaoh, Ramesses VI. They led to the tomb of Tutankhamun, a pharaoh who had died as a teenager more than 3,200 years earlier. On November 26, 1922, the team reached a second sealed doorway with treasures behind it. Removing the contents took about 10 years. (a) How many years ago was the step found? How many days passed before the team reached the second doorway? (b) Why might a tomb sitting below another tomb stay hidden for so long? (c) The discovery is often credited to Carter alone. Who else deserves credit, and why does it matter? (d) Name something that objects in a tomb can teach us that a written record might not.
Answer and teacher notes
(a) 2026 − 1922 = 104 years. November 26 − November 4 = 22 days. (b) Answers will vary: people looking for tombs may have focused on the later tomb above it, and material on top of it could have covered the entrance. (c) Answers will vary: the Egyptian workers who made up nearly all of the team, the person who actually spotted the step, and Lord Carnarvon, who paid for the digging. Credit shapes whose work gets remembered. (d) Answers will vary: what people ate, played, and wore, and what crafts and skills they had.
Live Science describes the group as British-led and made up almost entirely of Egyptians. The tomb held everyday items such as board games and beds as well as a 22-pound solid-gold mask, which supports answers to (d). Britannica notes that Carter’s work with Lord Carnarvon began around 1907. Good source practice: the “mummy’s curse” grew out of coincidences and news coverage. Live Science reports a 2002 study of 25 Westerners exposed to the tomb, who lived about as long as expected. Extension: why would a curse story spread faster than a study about ordinary life spans?

Current Events
NASA says Voyager 1, launched in 1977, will reach a distance of one light-day from Earth on November 18. That is how far light travels in one day: 16.09 billion miles (25.89 billion kilometers). Voyager 1 is moving at about 38,000 miles per hour. Light travels about 186,000 miles per second. (a) There are 86,400 seconds in a day. About how far does light travel in one day? How close is your answer to NASA’s number? (b) Radio signals travel at the speed of light. If engineers send a command at 9:00 a.m. Monday, when is the earliest they could get a reply? (c) How many miles does Voyager 1 travel in one day? (d) Both Voyager spacecraft lose about 4 watts of power each year. Why would engineers turn off some instruments? (e) Why might a scientist say “one light-day” instead of “16.09 billion miles”?
Answer and teacher notes
(a) 186,000 × 86,400 = 16,070,400,000, or about 16.07 billion miles. That is within about 0.02 billion miles of NASA’s number. (b) 24 hours out plus 24 hours back = 9:00 a.m. Wednesday. (c) 38,000 × 24 = 912,000 miles. (d) Answers will vary: with less power each year, turning off some parts leaves enough for the most important systems so the mission can keep going. (e) Answers will vary: the number is easier to say and remember, and it also tells you how long a signal takes.
The answer in (a) is a little low because 186,000 is a rounded speed. Common mistake on (b): counting only one direction. NASA’s November skywatching page lists the milestone on November 17, while JPL says November 18, and EarthSky gives 12:16 a.m. CST on November 18, so the date depends on time zone and source. Voyager 1 launched on September 5, 1977, and took a little over 49 years to get there. Extension: at 912,000 miles per day, about how many years would it take to go 16.09 billion miles? (16,090,000,000 ÷ 912,000 ≈ 17,643 days, or about 48 years. That is close to its real trip, but the speed was not the same the whole way.)
