Learn on PengiVocabulary from Classical Roots (Book 5)Chapter 3: Lesson 9-11

Lesson 11: Pulling Together

In Lesson 11 of Chapter 3 from Vocabulary from Classical Roots Book 5, Grade 3 students explore the Latin roots struct (build) and tract (pull) to understand words like construction, destructive, reconstruct, contraction, extract, protractor, retract, traction, and structure. Students practice identifying antonyms, using vocabulary in context, and expanding their knowledge of the prefix ex- and its variant e-, which both mean "out." This lesson builds word analysis skills by connecting root meanings to real-world concepts in grammar, math, and everyday language.

Section 1

Building Up with 'Struct'

Let's start with words that all share the Latin root 'struct', which means 'to build'. Think of these words as different ways to put things together... or take them apart!

Key Words

construction (n.)destructive (adj.)
reconstruct (v.)structure (n.)

📝Example Usage:

  • The team celebrated the rapid construction of the new bridge, which was finished ahead of schedule.
  • After the fire, it was too difficult to reconstruct the old building, so they had to tear down the entire structure.

Section 2

Pulling Together with 'Tract'

Now for words from the root 'tract', meaning 'to pull or drag'. These words describe different kinds of pulling, from ideas and objects to muscles and tires on a road.

Key Words

contraction (n.)extract (v.)protractor (n.)
retract (v.)traction (n.)

📝Example Usage:

  • The newspaper was forced to retract its story when new evidence proved the original claim was false.
  • To get enough traction on the icy driveway, the driver had to put chains on the tires.
  • The student used a protractor to measure the angles for her geometry homework.
