Assessing multi-step decimal problem-solving skills (Grade 6 test)

📚 Quick Study Guide

• ➕ When adding or subtracting decimals, make sure to line up the decimal points.
• ✖️ When multiplying decimals, multiply as you would with whole numbers, then count the total number of decimal places in the factors and apply that to the product.
• ➗ When dividing decimals, make the divisor a whole number by moving the decimal point. Move the decimal point in the dividend the same number of places.
• 🧮 Remember the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
• 💰 When solving word problems, identify the key information and what the problem is asking you to find. Estimate your answer to check if your final answer is reasonable.
