Our Take:By the end of year four, students should have memorized their basic multiplication and division facts up to 100. Grasping these facts requires experiences that extend well beyond drills and timed tests. Students should have varied learning opportunities to discover patterns and relationships within multiplication facts and build a firm understanding of the relationship between multiplication and division. One fun and engaging related learning activity involves playing "Around the World" with multiplication fact flash cards.
These exercises can help students practise this Common Core State Standards skill.
