Test questions on understanding picture graph keys (3rd Grade)

📚 Quick Study Guide

• 🔢 Understanding the Key: The key tells you how many each picture represents. For example, if each apple 🍎 in the graph represents 5 actual apples, then two apples in the graph mean 10 actual apples.
• 📊 Reading the Graph: Count the number of pictures and multiply by the value shown in the key to find the total for that category.
• ➕ Combining Categories: To find the total of multiple categories, simply add the values you found for each category.
• ➖ Comparing Categories: To find the difference between categories, subtract the smaller value from the larger value.
• 🧮 Using Half Symbols: Sometimes a half symbol is used to represent half the value in the key. If the key says an apple 🍎 is 5, then half an apple would be 2.5.
