Test your skills: Grade 3 multiplication strategies assessment

📚 Quick Study Guide

• ➕ Multiplication is a shortcut for repeated addition. For example, $3 \times 4$ means adding 3 four times: $3+3+3+3 = 12$.
• 🔢 A multiplication fact is a statement of what you get when you multiply two numbers. For instance, $5 \times 6 = 30$ is a fact.
• 🤝 Commutative Property: The order in which you multiply numbers doesn't change the answer. $a \times b = b \times a$. For example, $2 \times 7 = 7 \times 2 = 14$.
• 🧮 Associative Property: When multiplying three or more numbers, the grouping doesn't change the product. $(a \times b) \times c = a \times (b \times c)$. For example, $(2 \times 3) \times 4 = 2 \times (3 \times 4) = 24$.
• 💡 Zero Property: Any number multiplied by zero equals zero. $a \times 0 = 0$. For example, $9 \times 0 = 0$.
• ☝️ Identity Property: Any number multiplied by one equals that number. $a \times 1 = a$. For example, $6 \times 1 = 6$.
• 📝 Strategies include using arrays, equal groups, number lines, and repeated addition to visualize and solve multiplication problems.
