Test questions on arrays for division: Grade 3 assessment

📚 Quick Study Guide

• 🔢 An array is a way to organize objects into equal rows and columns. Think of it like a seating arrangement in a movie theater!
• ➗ Division is splitting a number into equal groups. It's the opposite of multiplication.
• 🧮 When dividing using arrays, the total number of objects is divided by the number of rows (or columns) to find the number of objects in each column (or row).
• 📝 For example, if you have 12 objects in an array with 3 rows, you divide 12 by 3 to find that there are 4 objects in each row ($12 \div 3 = 4$).
• 💡 Remember, each row must have the same number of items!
