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

An eponym is a word that comes from a person’s name. Use the clues to match each person with a word from this bank: braille, pasteurize, sandwich, volt. Then write one sentence that uses any two of the words correctly.

  1. John Montagu, an English earl, gave his title to a meal of food between slices of bread.
  2. Alessandro Volta invented the electric battery, and a unit used to measure electricity honors him.
  3. Louis Braille gave his name to a system of raised dots that blind people read by touch.
  4. Louis Pasteur showed that heating wine and beer could stop them from spoiling. Today the same idea makes milk safer to drink.
Answer and teacher notes

1. sandwich
2. volt
3. braille
4. pasteurize
Sentence: Answers will vary. Sample: “I ate a sandwich while I read about why a battery’s volts matter.”

Common mistake: thinking the Earl of Sandwich invented the food. Britannica says the word is named after him but treats the famous story, that he wanted to keep gambling while he ate, as doubtful. Word-origin notes are a good way to practice telling a fact from a good story. Each braille character fits in a cell of six dots, arranged in two columns of three. Extension: if a word were named after you, what would it mean? Write a one-sentence dictionary definition.

Math

A sandwich shop recorded how many sandwiches it sold each day for one week. On Sunday, the shop closed early.

Mon 42 | Tue 38 | Wed 55 | Thu 42 | Fri 61 | Sat 46 | Sun 7

  1. Find the mean. Round to the nearest tenth.
  2. Find the median.
  3. Find the mode.
  4. Find the range.
  5. Remove Sunday. Find the new mean and median. Which one changed more? Which better describes a typical day, and why?
Answer and teacher notes

In order: 7, 38, 42, 42, 46, 55, 61.
1. Total = 291. 291 ÷ 7 ≈ 41.6 sandwiches.
2. The middle (fourth) value is 42.
3. 42 appears twice, so the mode is 42.
4. 61 − 7 = 54.
5. Without Sunday: 284 ÷ 6 ≈ 47.3 for the mean. The median is (42 + 46) ÷ 2 = 44. The mean rose about 5.8, while the median rose 2, so the mean changed more. The median better describes a typical day because one unusual day barely moves it.

Common mistake on #2: using the numbers in day order instead of sorting them first. On #5, with six values, the median is the mean of the two middle values. The numbers are made up for practice. Check on #1: 7 × 41.6 = 291.2, close to 291. ✓ Extension: suppose Sunday had been a huge day of 150 sandwiches. Would the mean or the median change more?

Science

This week and next, Earth passes through dusty debris that gives us the Taurid meteor showers. The American Meteor Society lists the Southern Taurids peaking on November 4–5 and the Northern Taurids peaking on November 11–12. Each produces about 5 meteors per hour under ideal conditions, and they enter the air at about 27 to 29 kilometers per second. NASA uses three different words: a meteoroid is a space rock still in space, a meteor is one burning up in a planet’s atmosphere, and a meteorite is one that reaches the ground. (a) Which word fits a bright streak in the sky? A rock in a museum? A speck of dust drifting in space? (b) Why do people call meteors “shooting stars,” and why is that name misleading? (c) At 27 km/s, how far does a Southern Taurid travel in one minute? (d) A meteor shower returns at about the same time each year. Use Earth’s orbit to explain why.

Answer and teacher notes

(a) Streak: meteor. Museum rock: meteorite. Dust in space: meteoroid. (b) They look like tiny stars moving quickly across the sky, but they are small pieces of rock and dust burning up in Earth’s atmosphere, not stars. (c) 27 × 60 = 1,620 kilometers. (d) Earth follows nearly the same path around the Sun each year, so it crosses the same trail of comet dust at about the same time.

Memory trick: a meteorite has hit the ground. NASA calls a meteor brighter than Venus a fireball, and the American Meteor Society describes 2026 as a fireball swarm year for the Southern Taurids. The 5-per-hour rate is a best case, so the number you actually see will often be lower. Sources disagree a little on where the Northern Taurids come from: the American Meteor Society lists Comet 2P/Encke, while Star Walk connects them to asteroid 2004 TG10. Extension: 1,620 km is a big distance. Find a city about that far from where you live.

Social Studies

On November 3, 1903, Panama declared its independence from Colombia. The United States wanted to build a canal across the narrow land there, but Colombia’s congress had rejected a treaty that would have allowed it. After Panama declared independence, the United States sent warships to Panama City and Colón. A new treaty gave the United States a 10-mile-wide strip of land for the canal, which opened on August 15, 1914. (a) How many years ago did Panama declare independence? (b) About how many years passed between independence and the canal’s opening? (c) Find Panama on a map. Why would ships want a canal there instead of sailing around South America? (d) List one reason people in Panama might have supported independence and one reason people in Colombia might have been upset.

Answer and teacher notes

(a) 2026 − 1903 = 123 years. (b) November 1903 to August 1914 is almost 11 years (10 years, 9 months). (c) Panama is a narrow strip of land between the Atlantic and Pacific oceans, so a canal saves a long trip around South America. (d) Answers will vary. Panama: a chance to govern itself and to benefit from a canal. Colombia: it lost territory and the chance to control a valuable route.

The Office of the Historian says Colombia’s congress objected to the treaty’s financial terms. It also notes that the Hay-Bunau-Varilla Treaty required a $10 million payment to Panama plus yearly payments, and that U.S. control of the canal later became a source of tension. Encourage students to name a reason for each side instead of picking a side. Extension: look at a map of the canal. Why is the shortest route across a map not always the easiest place to dig?

Current Events

NASA’s Perseverance rover now holds the record for the farthest distance driven on another world. On October 11, 2026, its Mars day number 2,006 (Sol 2006), its total reached 45.22 kilometers. That passed the 45.16 kilometers driven by the Opportunity rover. On that day it drove 91.31 meters. On Sol 1947, it had been just 200 meters short of the record, but the team first spent weeks studying ancient rocks. (a) By how many meters did the rover’s total pass Opportunity’s? (b) How many sols passed between Sol 1947 and Sol 2006? (c) About how many meters did Perseverance average per sol over 2,006 sols? Round to the nearest tenth. (d) About how many times the average was the 91.31-meter drive? (e) Why might a science team wait to break a record?

Answer and teacher notes

(a) 45.22 − 45.16 = 0.06 km = 60 meters. (b) 2,006 − 1,947 = 59 sols. (c) 45.22 km = 45,220 m, and 45,220 ÷ 2,006 ≈ 22.5 meters per sol. (d) 91.31 ÷ 22.5 ≈ 4 times. (e) Answers will vary: the rover’s purpose is science, the rocks might not be reachable later, and the record would still be there after the work was done.

Common mistake on (a): leaving the answer in kilometers. Remind students that 1 kilometer = 1,000 meters. Guinness World Records also recognized the record. The average in (c) includes days when the rover did not drive at all, so it is not its speed while moving. Guinness reports that Opportunity reached 3.7 centimeters per second on straight drives. Extension: at that speed, how many minutes would it take to drive 91.31 meters without stopping? (9,131 ÷ 3.7 ≈ 2,468 seconds, or about 41 minutes.)
