  1. Introduce a challenge activity where students will create their own addition and subtraction equations with missing numbers. They can work individually or in pairs.
  2. Provide a set of number cards or manipulatives for students to use as they create their equations. Encourage them to use different numbers and operations to make their equations more challenging.
  3. Once students have created their equations, have them exchange papers with a partner and solve each other’s equations. They can use the number cards or manipulatives to help them find the missing numbers.
  4. After solving their partner’s equations, students can discuss their thought process and strategies with their partner. Encourage them to explain how they balanced the equation and found the missing number.
  5. As a closing activity, have students share their favorite equation that they created and solved with the class. This will allow for further discussion and reinforcement of the concept of equivalency.
  6. To further extend the lesson, provide additional worksheets or online resources for students to practice balancing addition and subtraction equations with missing numbers independently.
