Materials and Prep

• Pencil
• Blank paper or a notebook

No prior knowledge or preparation is required for this lesson.

Activities

1. Activity 1: Addition with Objects

   Gather some small objects like coins or buttons. Start with a small number, let's say 3. Place 3 objects in front of you. Now, ask a family member or friend to give you 2 more objects. Count all the objects together and write down the total number.

2. Activity 2: Subtraction with Fingers

   Hold up both of your hands. Start with all your fingers up. Now, put down 4 fingers. How many fingers are still up? Write down the answer.

3. Activity 3: Addition and Subtraction Practice

   Write down the following problems on your paper:

   • 5 + 2 = ?
   • 8 - 3 = ?
   • 6 + 1 = ?
   • 9 - 4 = ?

   Try to solve each problem by counting objects or using your fingers. Write down the answers.

First Grade Talking Points

• "Addition is when we put two or more numbers together to find the total. For example, if we have 3 apples and 2 more apples, we can add them together to find out how many apples we have in total."
• "Subtraction is when we take away a number from another number. For example, if we have 8 candies and we eat 3 candies, we can subtract 3 from 8 to find out how many candies are left."
• "When we add or subtract, we can use objects or our fingers to help us count. This makes it easier to find the answer."
• "Let's practice addition and subtraction together. Remember to count carefully and write down your answers."
