Learn on PengiVocabulary from Classical Roots (Book 5)Chapter 1: Lesson 1-3

Lesson 2: Balancing Evenly

In this Grade 3 vocabulary lesson from Vocabulary from Classical Roots Book 5, students explore the Latin roots equ (same, even, equal) and pend (hanging, weighing in the balance) to build meaning for eight words including equality, equilateral, equidistant, pendulum, and dependent. Exercises guide students to use root clues, synonyms, and context passages to connect word meanings to real-world concepts like geometry and timekeeping. The lesson also introduces the prefix quadr- to extend understanding of number-based word parts.

Section 1

The Root 'equ': All About Equality

Let's explore words that share the root 'equ,' meaning 'same,' 'even,' or 'equal.' These words help us talk about balance and fairness in math, geography, and society.

Key Words

equality (n.)equate (v.)equator (n.)
equidistant (adj.)equilateral (adj.)

📝Example Usage:

  • An equilateral triangle is a shape that has three equal sides.
  • Many people around the world are working for equality to ensure fairness for everyone, which is a state of being equal.

🧠Memory Trick

  • To achieve true equality, we shouldn't simply equate our world to a perfect shape, because even if a town is on the equator, it may not be equidistant from the sides of an equilateral country.

Section 2

The Root 'pend': Hanging in the Balance

Now for words from the root 'pend,' which means 'hanging' or 'weighing in the balance.' These words often describe things that are waiting or relying on something else.

Key Words

dependent (adj.)pending (adj.)
pendulum (n.)

📝Example Usage:

  • A young child is dependent on their parents for food and care, meaning they rely on them.
  • The approval for the new park is still pending, so the decision is not yet final.

🧠Memory Trick

  • The dependent cat watched the clock's pendulum swing back and forth, its adoption status left pending until the family returned.
