Christine, I’d say combining more physical and visuals with the auditory of the words is my first instinct.  Have students line up and tell one student to go “before” a specific child and another kid to go ‘after’ that child and discuss what it means to be “before” and “after.”  Then take the number path and cover all the numbers except a specific one and ask the students what number comes ‘before’ it and what number is ‘after’ it.

Make some cards with numerals on them and pick one card out and then ask them to find the card that goes before and the one that goes after.  Clothesline Math activities are another great way to do it.  Kristen Acosta did a session about it at the 2023 Virtual Math Summit, you can access it here: https://pd.buildmathminds.com/courses/2023-virtual-math-summit/lessons/vms23/topic/kristen-acosta-23/

Also, if you aren’t familiar with the Learning Trajectories site, I’d recommend getting a free account on there and explore around for other ideas.  Two of the authors of Number Worlds (Clements & Sarama) are the creators of the Learning Trajectories site. https://www.learningtrajectories.org/early-math/birth-to-grade-3
