Use Formal Methods For Subtraction of Integers WORKSHEET DESCRIPTION

students will take a deep dive into subtraction whilst working through this worksheet. Section A kicks off by asking learners to identify words from a given list that are frequently used for subtraction.

Next, in section B students complete 4 column subtraction questions where the numbers are already drawn out on a square grid. Then learners will complete four further subtraction questions however this time they will have to put the numbers into the column layout themselves before completing the subtraction. A square grid is provided. Included is a subtraction of two numbers in word form.

In section D students will identify equivalent calculations to aid them with their mental and written methods for subtraction. Lastly, section D challenges learners' understanding of the use of the column method as they have to fill the boxes to complete three column subtractions.
