Grade 1 Math Lesson Plan: Introduction to Addition

Lesson Title: Adding with Pictures

Duration: 45 minutes

Learning Objectives:

By the end of the lesson, students will be able to:

  1. Understand the concept of addition using pictures.
  2. Solve simple addition problems (sums within 10).
  3. Use counting strategies to find the sum.

Materials Needed:

  • Whiteboard and markers
  • Picture cards (with objects such as apples, stars, or toys)
  • Counting manipulatives (like blocks or counters)
  • Addition worksheets with pictures
  • Crayons or colored pencils

Lesson Outline:

  1. Introduction (10 minutes)

    • Begin with a short discussion about addition. Ask students if they know what it means to add numbers.
    • Explain that addition is putting things together to find out how many there are in total.
    • Introduce addition vocabulary: "plus," "equals," and "sum."

  2. Direct Instruction (10 minutes)

    • Show an example on the whiteboard.
      • Example: Draw two apples and then draw three more apples next to them.
      • Ask the students how many apples there are in total.
    • Write the corresponding equation: 2 + 3 = 5.
    • Explain that the plus sign (+) means to add and the equals sign (=) shows us the total.

  3. Guided Practice (10 minutes)

    • Distribute picture cards to partners. Each partner should have a set of cards showing different objects.
    • Instruct students to work together to create their own addition problems using the picture cards. For instance, if one has 4 stars and the other has 2 stars, they can create the equation: 4 + 2.
    • Circulate around the room to assist students and ensure understanding.

  4. Independent Practice (10 minutes)

    • Hand out addition worksheets with pictures of objects (e.g., animals, fruits) where students will draw or color in groups of objects to solve addition problems.
    • Example problems:
      • How many total apples are there if you have 3 apples and your friend gives you 2 more?
      • Draw 5 oranges and 2 bananas. How many fruits are there in total?
    • Encourage students to write down the equations for each problem they solve.

  5. Closure (5 minutes)

    • Gather students back together and ask a few of them to share one of their problems and the total they found.
    • Reinforce the idea that addition means putting things together and emphasize the importance of counting carefully.
    • Summarize the day’s lesson and remind students that they can always add things together in their everyday life.

Assessment:

  • Monitor students during group discussions and independent practice.
  • Review their completed worksheets to assess understanding of addition.

Modifications:

  • For students who need extra support, provide tangible manipulative items (such as physical blocks) to help visualize the addition.
  • For advanced learners, include simple addition with challenges (e.g., adding sets that are not shown in pictures).

This lesson plan introduces first graders to the basics of addition in an engaging, interactive, and visual way, while providing opportunities for students to practice and demonstrate their understanding.
