Questions & Answers

Question: I don't understand how to compare big numbers in data sets. How do I know which is bigger?

Answer: Great question! Here's how to compare numbers in data sets:

  • Read each value carefully: Look at each number in the data set separately
  • Compare systematically: Put the numbers in order from smallest to largest
  • Use comparison symbols: > means greater than, < means less than, = means equal

For example: If you have Apples: 12 and Bananas: 8, you can see that 12 > 8, so apples are more than bananas. The larger number always means more items in that category!

Question: When my child needs to find how many more of one thing than another, what strategy should they use?

Answer: Use this simple strategy:

  • Read both values: Find the number for each category mentioned
  • Identify larger and smaller: Determine which number is bigger and which is smaller
  • Subtract: Take the smaller number away from the larger number
  • State the difference: This is how many more of the larger category there is

For example: If there are 12 apples and 8 bananas, the difference is 12 - 8 = 4. So there are 4 more apples than bananas.

Question: How do I know if I'm reading the data correctly? Sometimes I mix up the numbers.

Answer: Here are tips to read data correctly:

  • Read slowly: Look at each category and its value carefully
  • Point and read: Use your finger to point to each value as you read it
  • Write down values: Jot down each number before comparing them

For example: If you see "Apples: 12, Bananas: 8", write down A=12 and B=8, then you can easily see that 12 > 8. Writing things down helps prevent mixing up numbers!
