Fun Way to Learn Missing Numbers in Subtraction!
Hi everyone! Are you ready to solve a fun math puzzle today? Subtraction is like playing a game of hide-and-seek with numbers. Sometimes, one of the numbers decides to hide, and it is our job to find out who is missing!
When we look at a subtraction problem like 17 - __ = 10, we just need to ask ourselves: "How many do I need to take away from 17 to leave 10?" Or we can turn it around and think: 17 - 10 = 7! That means the missing number in the box is 7!

How Teachers and Parents Can Guide Children
If your little learner gets stuck, try using small physical objects like blocks, counters, or colorful buttons:
- Start with the bigger number using real objects (for example, 14 blocks).
- Look at the answer at the end of the line (for example, 2).
- Remove blocks until only 2 are left in your hand. Count how many blocks you set aside—that's your missing number!
