Have your students spring ahead with some pattern practice! First, they can try some more basic patterns - adding and/or subtracting. Once they've gotten into the groove, they can try a couple of more challenging patterns. Now that they are warmed up - they can create a few of their own patterns for a friend to solve! Then - they can move on to the picture patterns and letter patterns!
Suggestion: When my students are creating their own patterns, I like to give them number tiles to work with before they finalize their pattern for a friend to try.
