Let's
Practice Subtraction up to 99
Students
learn to subtract 2 digit numbers from numbers up to 99. The activities
are divided into four sections. Each section covers a different aspect of
subtraction.
Part A vertical arrangement: ?> · Subtracting multiples of 10 from numbers in the range of 50 · Subtracting multiples of 10 from numbers in the range of 99 · Subtracting 2 digit numbers from any numbers up to 99 · Progressing gradually to more difficult subtraction algorithms
Part B horizontal arrangement:
· Subtracting multiples of 10 from numbers in the range of 99 · Subtracting once from numbers in the range of 99
One section deals with money. Both vertical and horizontal forms of subtraction are included to imply the concept of place value, emphasising that the first digits are tens, the second are ones, and that we subtract from the ones first and then from the tens. Money is used to reinforce the concept of place value, notes and coins are used to demonstrate the concept of tens and ones. Let's Practice Subtraction is compatible with the LUK self checking system. The LUK patterns are at the back of the workbook, rather than on the bottom of pages.
