Here's a trick for subtracting: think addition! 14 minus 8 asks: 8 plus what makes 14?
Count up from 8 to 14: 9, 10, 11, 12, 13, 14. That's 6. So 14 minus 8 is 6.
Or use a fact you know: 8 plus 6 is 14. So 14 minus 8 is 6!
Here's a story: Jenny had 10 pencils and gave some to Eric. Now Jenny has 8. How many did Jenny give? Think: 8 plus what makes 10? She gave 2.
Subtracting is finding a missing part. Think addition to find it.
