Addition Hills
Observe the pattern and fill up the blocks to reach the top of the hill. The 
first one is done for you.
Now make an addition hill of your own. Ask your partner to solve it.
Rule: Each block is the sum
total of the two blocsk on
which it rests. For example,
we add 7 + 6 = 13 and
6 + 5 = 1

63 92 6221 68 7
Try it!
You can also make similar addition patterns.
Always remember that the numbers of
steps you want in your hill, will be equal
to the numbers you take at the base.
For example, 5 numbers
at the base = 5 step hill.

This classification helps to understand how different approaches affect relationships and outcomes.
3. What evidence does the book provide to support the benefits of being a giver?

4. Can you explain the concept of "success through collaboration" as discussed in the book?
Ans. The concept of "success through collaboration" suggests that working together and helping others can lead to better results for everyone involved. The book argues that individuals who embrace collaboration tend to foster a more supportive environment, which ultimately enhances individual and collective success.

Ans. The book recommends several strategies for becoming a more effective giver, such as setting boundaries to protect oneself from burnout, being strategic about when and how to help others, and seeking win-win situations where both parties benefit.
