Place Value within 50 - One more one less 2 - Worksheet

The worksheet series titled "Place Value within 50 - One More One Less" is designed to enhance children's understanding of place value, focusing on identifying the number that is one more or one less than a given number up to 50. The exercises involve using a number track to support children in recognizing and calculating these values. The initial tasks concentrate on situations where only the ones digit changes, helping to cement the concept of incrementing and decrementing within the same ten. As the worksheets progress, challenges are introduced where both the tens and ones digits may change, offering a more complex level of reasoning and problem-solving.

Further activities within the worksheets require children to identify 'one more' and 'one less' when presented with an incomplete number track, where the target number is obscured, encouraging them to infer the missing number based on the sequence. In addition to fluency and precision tasks, the worksheets also include reasoning and problem-solving sections. Here, children are asked to spot mistakes, such as identifying an incorrect predecessor or successor of a number, and use given clues to deduce a secret number. The clues are designed to prompt children to think about the properties of numbers, such as the number of tens and the effect of adding or subtracting one on the digits. Answers are provided to facilitate self-correction and to help teachers assess understanding and guide further learning.
