Question 33 of 33intermediate🔧 ApplyShort Answer3 marks

Make a number strip in the playground or at home and find the different ways by which you can reach to the same place.

Correct Answer

Activity: Students create a number strip (number line) from 0 to 20 on the ground.

Finding: They discover multiple ways to reach the same number.

Example 1 — To reach 10:

  • Hop 5 + 5
  • Hop 7 + 3
  • Hop 8 + 2
  • Hop 6 + 4

Example 2 — To reach 15:

  • Hop 10 + 5
  • Hop 8 + 7
  • Hop 9 + 6

Conclusion: This demonstrates that different addition combinations can give the same sum, reinforcing addition facts and the commutative property.

Explanation

This hands-on activity helps students understand that multiple addition combinations can result in the same sum. By physically hopping on the number strip, students develop number sense and memorize addition facts kinesthetically.

Solution Steps

  1. Create a number strip (number line) from 0 to 20 on the ground.

  2. Find multiple ways to reach the same number by hopping.

  3. To reach 10: hop 5+5, 7+3, 8+2, or 6+4.

  4. To reach 15: hop 10+5, 8+7, or 9+6.

  5. Observe that different addition combinations give the same sum.
