### TEACHING TIPS

Use concrete examples and hands-on activities to help students understand the concept of missing numbers on a number line.

### STUDENT MISCONCEPTIONS

Common misconceptions when identifying missing numbers on a number line up to 120 include:

1. Skipping numbers: Students may skip numbers while counting or skip counting, leading to errors in identifying missing numbers on the number line.

2. Counting by ones: Students may try to count by ones to identify the missing number, which can be time-consuming and confusing, especially for larger numbers.

3. Confusing the placement of numbers: Students may have difficulty placing numbers correctly on the number line, leading to errors in identifying missing numbers.

4. Not recognizing the pattern: Students may not recognize the pattern of the numbers on the number line and therefore have difficulty identifying the missing number.

5. Difficulty with place value: Students may struggle with understanding place value and the significance of the position of the digits in a number, leading to errors in identifying the missing number.

### STANDARD

##### Common Core Standard:

1.NBT.A.1 - Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
