Master Subject & Predicate: Hands-On Sentence Building Lesson

This hands-on grammar lesson uses color-coding (Red/Blue) to teach students how to identify the Subject and Predicate. Includes "Sentence Surgery" and "Chef" activities for mastering sentence structure and building strong, complete sentences.

Building Blocks of Sentences: Subject & Predicate Superstars!

Materials Needed

  • Paper (regular or cardstock)
  • Markers or highlighters (two different colors, e.g., red and blue)
  • Scissors
  • Pre-written simple sentences (5-8 examples, see examples in 'We Do' section)
  • Worksheet/Notebook for recording
  • A large envelope or container (to store sentence pieces)

Introduction: The Perfect Match

Hook (5 minutes)

Educator Prompt: Imagine you are building a spectacular LEGO castle, but you only have the roof pieces! Or imagine eating a sandwich that is only bread! Is it complete? No! Just like a great sandwich needs two main parts (the bread and the filling), a strong sentence needs two main parts to be complete and make sense. If a sentence is missing one part, it’s like a mystery or a whisper that doesn't finish!

Learning Objectives (Success Criteria)

By the end of this lesson, Valentina (and all learners) will be able to:

  1. Identify the two main parts of a simple sentence: the Subject and the Predicate.
  2. Explain the job of the Subject (the 'who' or 'what').
  3. Explain the job of the Predicate (the 'action' or 'doing').
  4. Combine a Subject and a Predicate correctly to build complete, strong sentences.

Success looks like: Being able to point to any sentence and correctly draw a line separating the "who/what" part from the "doing" part.

Lesson Body: The Sentence Team

Phase 1: I Do (Modeling the Concepts) (10 minutes)

Topic: Identifying the Subject (The Star Player)

Educator Talk: The first important part of our sentence team is the Subject. The Subject is always the 'who' or the 'what' the sentence is about. Think of it as the star player of the sentence! We will use the RED color marker for the Subject.

  • Question to find the Subject: Who or what is doing the action?

Modeling Example:

Sentence: The happy dog chased the ball.

I ask myself: "Who or what is doing the chasing?" The answer is The happy dog. I underline that part in RED. That is our Subject.

Topic: Identifying the Predicate (The Action)

Educator Talk: The second important part is the Predicate. The Predicate tells us what the Subject is doing, or sometimes what the Subject is being. It always includes the main action word (the verb). We will use the BLUE color marker for the Predicate.

  • Question to find the Predicate: What did the Subject do?

Modeling Example (Continuing):

Sentence: The happy dog chased the ball.

I ask myself: "What did the happy dog do?" The answer is chased the ball. I underline that part in BLUE. That is our Predicate.

Phase 2: We Do (Guided Practice - Sentence Surgery) (15 minutes)

Activity: Sentence Surgery

Goal: Learners physically separate Subjects and Predicates.

  1. Preparation: The educator writes the following simple sentences clearly on strips of paper, ready to be cut:
    • The tiny bird / sang a cheerful song.
    • My busy teacher / graded the papers quickly.
    • The yellow banana / slipped onto the floor.
    • The fast race car / zoomed around the track.
  2. Identification: The learner reads the first sentence. Together, they use the RED marker to underline the Subject and the BLUE marker to underline the Predicate.
  3. The Cut: The learner carefully cuts the sentence strip exactly between the Subject and the Predicate.
  4. Mix and Match: Once all sentences are cut, the learner mixes all the RED (Subject) strips and all the BLUE (Predicate) strips into two separate piles.
  5. Recombination: The learner attempts to put the original sentences back together.

Formative Check-in

Discussion Prompt: Try putting Subject "The tiny bird" with Predicate "graded the papers quickly." Does that sentence make sense? Why not? (Answer: The Subject and Predicate must logically fit together, even though they are grammatically correct halves.)

Phase 3: You Do (Independent Practice - Sentence Chef) (15 minutes)

Activity: Sentence Chef Challenge

Goal: Learners generate their own Subject and Predicate ideas and combine them.

  1. Subject Generation: On 5 small red pieces of paper, the learner writes five different simple Subjects (e.g., My bicycle, Valentina, The noisy cat, A giant whale, The red backpack).
  2. Predicate Generation: On 5 small blue pieces of paper, the learner writes five different simple Predicates (actions) (e.g., jumped very high, ate all the cheese, walked home slowly, taught me a new word, will shine tomorrow).
  3. The Creation: The learner mixes the piles and pulls one Subject and one Predicate card at a time. They must write down the new sentence if it makes sense.
    • Example 1: The noisy cat + ate all the cheese. (Makes sense!)
    • Example 2: A giant whale + walked home slowly. (Does not make sense! Try a new match.)
  4. Recording: The learner writes at least five complete, logical sentences generated by their own Sentence Chef pairing in their notebook.

Differentiation and Adaptability

Scaffolding (Support for Struggling Learners)

  • Color Coding: Always use the red/blue color system for visual reinforcement.
  • Verb Focus: Before writing the Predicates, circle the main action word (verb) within each Predicate to ensure the learner recognizes its core.
  • Simplified Subjects: Start with simple noun subjects (e.g., *Dog, Teacher, Ball*) instead of phrases (e.g., *The big, fluffy dog*).

Extension (Challenge for Advanced Learners)

  • Expansion Challenge: Ask the learner to take the five successful sentences and expand them by adding describing words (adjectives or adverbs) to both the Subject and the Predicate. (Example: The noisy cat ate all the cheese. becomes The extremely noisy, hungry cat quickly ate all the delicious cheese.)
  • Compound Sentences: Introduce the concept of connecting two complete sentence teams (two Subjects and two Predicates) using coordinating conjunctions (like 'and' or 'but').

Adaptability Notes (Context Flexibility)

  • Classroom: Sentence Chef can be done in small groups. Each group generates 5 Subjects and 5 Predicates, shuffles them, and tries to create the most hilarious logical sentences.
  • Training/Adult Context: Use complex business or technical terms for Subjects (e.g., The quarterly budget, The new software implementation, The team leader) to practice identifying core action/purpose in professional writing.

Conclusion: Recap and Assessment

Recap (5 minutes)

Educator Prompt: Let's quickly remember the job of our sentence team. If I say "The Star Player," which part of the sentence am I talking about? (Subject). If I say "The Action," which part am I talking about? (Predicate).

A good sentence always needs both parts, and they must work together!

Summative Assessment: Exit Ticket

The learner completes three final tasks, using their knowledge:

  1. Write one sentence about something fun they did today.
  2. Draw a line separating the Subject from the Predicate in that sentence.
  3. In one short sentence, define the job of the Predicate. (Example answer: The predicate tells what the subject is doing.)

Reviewing the Sentence Chef Challenge sentences and the Exit Ticket provides clear evidence of objective mastery.
