Question: My child seems to struggle with the "making ten" strategy. Should I be concerned?

Answer: Not at all! The "making ten" strategy takes practice:

  • This is an advanced strategy that builds on basic addition facts
  • Your child might prefer other strategies like counting on or using doubles
  • Continue practicing with concrete objects (counters, blocks) to build understanding
  • Focus on mastering doubles and make-ten facts gradually

The key is flexibility - let your child use whatever strategy works best for them!

Question: I sometimes get the wrong answer even when I think I did everything right. What should I do?

Answer: Mistakes are normal and help us learn! Here's what to do:

  • Always check your answer by counting or using a different method
  • Look for patterns in your mistakes - are you always off by 1 or 2?
  • Ask for help when you're stuck - teachers and parents love helping!
  • Practice the same type of problem again to build confidence

Remember: every mathematician makes mistakes - the key is learning from them!
