Practice subtracting two-digit numbers from two digit numbers up to 99 (no regrouping).
The activities are divided into four sections, starting from subtracting multiples of 10, and gradually progressing to more difficult subtraction problems.
Money is used to reinforce the concept of place value, notes and coins are used to demonstrate the concept of tens and ones.
Both vertical and horizontal forms of subtraction are used to
reinforce the concept of place value.
The use of 24 questions (problems) makes the program compatible with the LUK self checking system.
