1 more, 1 less, 10 more, 10 less

Identifying 10 more, 10 less, 1 more, and 1 less than a two-digit number involves understanding the patterns in the base-10 number system.

- Introduction to Place Value:

Begin by reviewing or introducing the concept of place value. Remind students that each digit in a number has a specific place and value. - Visual Representation:

Use visual aids such as place value charts, drawings, or manipulatives to represent two-digit numbers. This helps students visualize the relationship between tens and ones. - Identify the Two-Digit Number:

Choose a two-digit number, for example, 45. - 10 More:

Explain that to find 10 more than a number, add 10 to the original number.

For 45, 45 + 10 = 55.

Emphasize that only the tens place changes. - 10 Less:

Similarly, explain that to find 10 less than a number, subtract 10 from the original number.

For 45, 45 − 10 = 35.

Again, highlight that only the tens place changes. - 1 More:
For finding 1 more than a number, add 1 to the original number.

For 45, 45 + 1 = 46. Emphasize that this change occurs in the ones place. - 1 Less:

For finding 1 less than a number, subtract 1 from the original number.

For 45, 45−1=44.

The ones place is affected in this case.

Understanding the relationships between a two-digit number and its variations (10 more, 10 less, 1 more, and 1 less) helps students develop a deeper grasp of place value and numerical patterns. Regular practice and interactive activities enhance their proficiency in these concepts.
