Learning About Number Bonds

What are number bonds? A number bond is a mental picture of the relationship between a number and the parts that combine to make it.

How can I use a number bond? A number bond help you to see how different numbers can be combined to make a bigger number. The bigger number represents the WHOLE and the other small number represent its PARTS.  If you know the parts (different number combinations), you can put them together (add) to find the whole. If you know the whole and one of the parts, you take away the part you know (subtract) to find the other part. In other words number bonds help you to add and subtract.

Example of a number bonds:

• 

• Number Bonds are very helpful because a young student who does not understand math notation can clearly see the connection between these numbers.

  • for example:

    • 4 + 2 = 6
      2 + 4 = 6
      6 – 4 = 2
      6 – 2 = 4

It is time to practice!!

• First, the teacher will how the following website in which students can practice

  • http://www.math-salamanders.com/number-bonds.html#zoneArea1

    • The teacher will provide instructions for groups to set the website first as a guided practice without setting the time to explain and reinforce the concept.

    • Then, when student feel ready, they will set the timer to practice independently.
