Model correct usage in a range of contexts including labelling abstract equations and using the term to identify the known elements in worded problems. Take time to show adjacent on number lines connecting to addition and subtraction of equal groups.

Keywords

Adjacent - Adjacent means next to each other.
Multiple - A multiple is the result of multiplying a number by another whole number.
