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. Worksheets 1 & 2 contain visual support to help introduce this topic. Worksheet Set 1 First addend: Multiples of ten between 100 to 900 Second addend: Multiple of 10 between 90 Worksheet Set 2 First addend: Multiples of ten between 100 to 900 Second addend: Between 11 and 99 Worksheets Sets 3 & 4 These follow the same range of numbers as above but the pupils can now choose how they lay out their workings to demonstrate their understanding of addition through bridging.
