After testing, consider setting up several centers for board games to be played. One of my family’s favorite games is actually a math game. Shut the Box can help students build fluency with addition facts and fact families. It is also fun for all ages! (My elderly parents play it to keep their minds young.)
If your students want more of a challenge, consider having them create their own board games. This could make a really good start for a project-based learning activity too.
