Early Addition Meaning

Overview

Today students are introduced to addition as joining amounts and to the meaning of the plus sign (+). Students model addition using pictures, objects, and simple number sentences.

Learning intentions

• Students will be able to explain what addition means in everyday terms (joining two groups).
• Students will understand that the plus sign shows “together” or “and”.
• Students will represent simple addition with objects, drawings, and number sentences.
• Students will solve and record addition facts to small totals using visual supports.

Success criteria

• I can tell what addition means using joining language (two groups become one).
• I can read a number sentence like 3 + 2 as “3 and 2 together”.
• I can show addition with counters or drawings and write the matching equation.
• I can check my answer by counting the combined set.

Curriculum links

• Number Sense and Numeration: developing understanding of whole numbers and addition for small quantities.
• Mathematical Thinking: using representations (concrete, pictorial, and symbolic) to show and explain thinking.
• Problem Solving: creating and solving simple addition problems with guidance.
• Communication: using mathematical language (plus, and, together) to explain reasoning.

Lesson structure (20 minutes)

1. 1–3 min: Hook with a story

• Tell a short, age-appropriate story: “I have 3 apples and I get 2 more. How many apples do I have now?”
• Ask: “What did we do? Did we take away or did we bring them together?”

2. 3–6 min: Introduce addition meaning

• Use a small group of objects (or quick drawings on the board) to show two sets placed side by side, then moved into one group.
• Say clearly: “Addition is joining two groups. We find the total.”
• Prompt students to repeat: “We join two groups to find how many altogether.”

3. 6–9 min: Teach the plus sign

• Write: 3 + 2 and point to the symbols.
• Explain: “The plus sign means ‘and’ or ‘together’—it shows joining.”
• Students turn-and-talk: “What does this mean? What could we draw or build?”

4. 9–13 min: Guided practice with representations

• Display two addition problems with small numbers (e.g., 4 + 1, 2 + 3). Keep totals within the range your class knows.
• For each problem, model three steps:
• Build with counters (or draw two groups).
• Count all to get the total.
• Write the matching equation using the plus sign.
• Ask a few students to explain how they know the answer (counting all).

5. 13–17 min: Student independent or pair task

• Give each student a short worksheet or mini task sheet with 3 addition prompts using pictures and blanks for the equation (for example: a picture showing 3 objects and 2 objects, then “__ + __ = __”).
• Students choose a method: counters, quick sketches, or number line drawings.
• Teacher circulates with targeted questions: “How do you know these are added together?” “What does the + mean here?”

6. 17–19 min: Quick whole-class share

• Select 2–3 student examples (volunteers). Confirm correct representations and equations.
• Emphasize correct reading of the number sentence (e.g., “3 + 2 = 5” is “3 and 2 together equals 5”).

7. 19–20 min: Exit check

• Students write or show one equation on a small card: Teacher says, “Show 3 and 1 together.”
• Collect quickly to check understanding of addition meaning and the plus sign.

Resources

• Counters or small Unifix cubes (enough for two small groups plus combining)
• Whiteboard and markers/chalk
• Picture cards showing “two groups” (e.g., apples, blocks, dots)
• Short worksheet or task sheet with 3 picture-based addition questions
• Student mini recording sheets (or scrap paper) for drawing counters
• Exit ticket cards (half sheets)
• Projector or document camera (optional)
• A bin or container to physically “join” two groups during modelling

Assessment

• Observation during guided practice: listens for correct joining language and correct counting of the total.
• Worksheet/task check: verifies students write matching equations with the plus sign and correct totals for pictured groups.
• Exit ticket: confirms students can translate “two groups together” into an addition sentence.

Differentiation

• Support:
• Provide sentence starters: “Addition is when we ____ two groups.”
• Offer a partially completed equation frame (e.g., ___ + ___ = ___) and fewer problems.
• Use colour-coded counters (Group A one colour, Group B another) to make “joining” visible.
• Extension:
• Add a challenge card with a slightly larger total or a “which equation matches the picture?” prompt.
• Ask students to explain using words: “The + means ______.”
• EAL/SEN:
• Pair students strategically for modelling and discussion.
• Use gestures while teaching: point to the two groups, then sweep hands together to represent joining.
• Keep numbers small and consistent; repeat vocabulary (“together”, “total”, “plus”).
• For students needing more structure:
• Provide a simple step strip: Build → Count all → Write equation.
