Subtract by bridging through 100s 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 subtraction rather than relying completely on the standard algorithm. This strategy can be particularly beneficial for visual learners.

Worksheets Set 1 - contains visual support to help introduce this topic (see the Preview)
1st number : A multiple of ten between 100 to 900
2nd number: A multiple of 10 between 20 and 90

Worksheets Set 2 - This follows the same range of numbers as above, but the pupils can now choose how they lay out their workings to demonstrate their understanding of subtraction through bridging.

Worksheet Set 3 - Subtract by bridging through 10 and 100
Having successfully mastered the initial stage of bridging 100, we now add in an additional step of bridging 10 with the 2nd number now being any number in the range from 11 to 99. This set contains the visual support as in Worksheet Set 1

Worksheet Set 4 - This follows the same question format of Worksheet Set 3, but the pupils can now choose how they lay out their workings to demonstrate their understanding of subtraction through bridging.

How many worksheets are in each set ?
(almost) Unlimited. At the click of a button all numbers are randomized, so you can create as many different worksheets as you need for classwork, homework, revision, preparing for assessment, fillers etc and the numbers will change every time.

Answers are automatically generated every time for all Worksheets,

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