Math Lessons and Practice Sheets This document includes lessons on key math concepts with warm-ups, explanations, and sample problems to reinforce learning. Use these sheets to build understanding before attempting the worksheets. Lesson 1: Multiplication **Warm-Up:** Solve these simple multiplication problems to get started: 1. 5 × 6 = _____ 2. 7 × 8 = _____ 3. 12 × 3 = _____ **Lesson:** Multiplication is a shortcut for adding the same number multiple times. For example, 5 × 3 means adding 5 three times (5 + 5 + 5 = 15). Use arrays, number lines, or groups to visualize multiplication. **Sample Problems:** 1. Draw an array for 4 × 3 and calculate the total. 2. Multiply: 14 × 6 = _____ 3. Solve: 125 × 4 = _____ Lesson 2: Word Problems **Warm-Up:** Read each problem and identify the operation to use: 1. A store sells 25 apples. If you buy 3 bags, how many apples do you get in total? 2. A runner jogs 7 miles each day for 5 days. How far does the runner jog in total? **Lesson:** Word problems require careful reading. Look for keywords: - Addition: total, combined, together - Subtraction: left, remaining, difference - Multiplication: times, groups of, product - Division: split, divided, per group **Sample Problems:** 1. A bakery bakes 15 loaves of bread every hour for 8 hours. How many loaves are baked? 2. A car travels 60 miles in the first hour and 50 miles in the second. What is the total distance? Lesson 3: Fractions, Decimals, and Percentages **Warm-Up:** Convert these fractions and percentages: 1. Convert 3/4 to a decimal. 2. What is 25% as a fraction? 3. Convert 0.75 to a percentage. **Lesson:** - Fractions represent parts of a whole. To convert to a decimal, divide the numerator by the denominator. - Decimals can be converted to percentages by multiplying by 100. - Percentages can be converted to decimals by dividing by 100. **Sample Problems:** 1. Add 2/5 and 3/10. Write the answer as a decimal. 2. What is 35% of 120? 3. Multiply 0.85 by 200. Lesson 4: Calculator Practice **Warm-Up:** Use a calculator to solve: 1. 125 × 34 = _____ 2. 78.5 ÷ 4 = _____ 3. 0.45 × 250 = _____ **Lesson:** Calculators are tools to speed up math. However, always estimate first to check if your answer makes sense. For example, before calculating 125 × 34, estimate: 120 × 30 = 3600. **Sample Problems:** 1. Multiply 0.75 by 400. 2. Find 45% of 1,200. 3. Divide 1,234 by 56.
