Let's solve each of the
number bond problems. A number bond shows how numbers can be split into parts. In this case, all the top numbers are
10, and we need to find the missing part that, when added to the given number, makes
10.
We use the equation:
>
Part + Part = Whole
> So:
Missing part = 10 - Given part

📝 Explanation:
Number bonds help students understand
addition and subtraction facts by showing how numbers relate. For example, knowing that 4 and 6 make 10 helps with both:
- 4 + 6 = 10
- 10 - 4 = 6
This reinforces mental math and number sense.
