Skip counting is an important math skill. There are many different ways to strengthen this skill. Here are a few of my favorites:
This is always my students' favorite activity. It is also a great activity to do when your students have too much energy! Make a number line on the floor. I like to use blue painter tape because it comes off the floor without leaving all the goo that other tapes leave behind.

When I introduce addition or subtraction, I make one number line. A volunteer hops up and down the number line to find the answer. Later on, I make a game out of it. I make 2 number lines. The class is divided into 2 teams. One person from each team stands beside their number line. I show them a flashcard with a problem. The student has to hop up or down the number line, demonstrating the problem, landing on the answer. The first person who hops up and down correctly earns a point for their team. This is a noisy activity, but perfect for an inside recess.
