Children can easily solve the problems 2 + 7 = ___. They find it more difficult to solve the following problems:
2 + _ = 9
9 = 2 + __
9 = __ + 2
This is a pack of materials which I developed to teach this concept to my class of 1st class. It contains printables to make manipulatives and Smartboard files on the topics. There are also two worksheets in the pack.
The materials can also be used to complete subtraction problems:
9 - __ = 7
7 = 9 - __
More information on how I used the materials can be found here
