Test Your Array Knowledge: Everyday Examples Grade 2

📚 Quick Study Guide

🔢 Arrays are a way to organize objects into rows and columns. ➕ An array helps us understand multiplication and repeated addition. 📐 Each row in an array has the same number of objects. 📝 We can write an array as a multiplication sentence, like: (number of rows) x (number of columns) = (total number of objects). 💡Arrays help make counting easier and faster!
