Add by bridging through 100 up to 1000
Bridging through 100s encourages students to develop strong mental math skills by breaking down numbers into smaller more manageable parts. Students get to visualize the connection between different place values and understand the concept of regrouping or carrying over. It also provides students with an alternative approach to addition rather than relying completely on the standard algorithm. This strategy can be particularly beneficial for visual learners.
