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.

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.

All Worksheets are Dynamic: At the click of a button all the numbers are randomized providing you with (an almost) unlimited set of questions for classwork, revision, homework, assessments etc.

Answers are automatically generated every time for all Worksheets.

There is a Teaching Page with an unlimited number of randomly generated questions covering the graphic layout of Worksheet Set 1 and 2 designed for use with the Interactive whiteboard to help you introduce or review the topic with your class or on a PC or Mac for one-to-one tuition.
