The document provides examples of one-step subtraction word problems that may be seen on KS2 maths SATs tests. It explains that these types of problems can be solved in one of two ways: 1) by counting on from the smaller number to the larger number, or 2) by subtracting the smaller number from the larger number. It provides examples like Barry having 65 chocolates and giving 19 to friends, so how many are left? (65 - 19 = 46). It also gives examples involving prices to find the difference.
