Worksheet 1: Basic Addition and Subtraction (within 20)

Name: Helen

Date: June 4^th

Part A: Compute

1. \( 7 + 5 = 12 \)


2. \( 12 - 4 = 8 \)


3. \( 9 + 8 = 17 \)


4. \( 15 - 6 = 9 \)

Part B: Solve the Equation

1. \( x + 3 = 10 \) → \( x = 10 - 3 \) → \( x = 7 \)


2. \( 8 - x = 5 \) → \( x = 8 - 5 \) → \( x = 3 \)

Part C: One-Step Word Problem

1. Tom has 6 apples. He buys 5 more. How many apples does he have now?
   

   Solution: \( 6 + 5 = 11 \) apples.

   
   

   Ответ: 11 яблок.

   
   

Part D: Two-Step Word Problem

1. Tom has 6 apples. He buys 5 more, but then he eats 2. How many apples does he have left?
   

   Solution: First, Tom has \( 6 + 5 = 11 \) apples. Then he eats 2, so he has \( 11 - 2 = 9 \) apples left.

   
   

   Ответ: 9 яблок.
