Making math feel like a game rather than a chore is the "secret sauce" for helping kids master numbers. When kids realize they can solve problems faster than a calculator can be turned on, their confidence skyrockets.
Round one number to the nearest ten to make it "friendly," solve the problem, and then adjust. Example: For 38 + 25 , turn 38 into 40 (by adding 2). The Math: . Now, take away that extra 2 you added earlier.
Here’s a deep dive into the mental math strategies that are actually fun for kids to learn. 1. The "Friendly Numbers" Strategy (Compensation) Mental Math Kids Can't Resist!: Tips, Short-cut...

Give the kid the "trick" and give yourself a calculator. Race to see who gets the answer first. (Let them win!)
