Objective

By the end of this lesson, the Grade 1 student will be able to understand and apply the concept of addition in Mathematics.

Materials and Prep

• Counting objects (such as buttons, coins, or small toys)
• Pen or pencil
• Plain paper or notebook

Before starting the lesson, the student should have a basic understanding of counting numbers from 1 to 10.

Activities

1. Activity 1: Counting and Adding Objects

   Ask the student to gather a small collection of counting objects (e.g., buttons, coins, or small toys).

   Have the student count the objects and write down the number on a piece of paper.

   Then, ask the student to add a specific number of objects to the collection (e.g., add 2 more buttons to the existing ones).

   Guide the student to count the new total and write it down as an addition equation (e.g., 5 + 2 = 7).

2. Activity 2: Addition Word Problems

   Present the student with simple addition word problems, such as:

   • "Sally has 3 apples. She buys 2 more apples. How many apples does Sally have now?"
   • "Tom has 4 marbles. He finds 3 more marbles. How many marbles does Tom have in total?"

   Encourage the student to solve the problems by counting the objects and writing down the addition equations.

United States of America: Grade 1 Talking Points

• "Addition is a mathematical operation that combines two or more numbers to find the total."
• "We can use addition to find out how many objects we have when we add more to a group."
• "When we add numbers, we start with the first number and count on to add the next number."
• "We write addition equations using the plus sign (+) and an equals sign (=)."
• "For example, if we have 3 apples and we add 2 more apples, we write it as 3 + 2 = 5."
