This hard worksheet introduces near-doubles reasoning and a real-world word problem alongside missing-addend challenges. Part A offers four multiple-choice questions where kindergartners use known doubles facts to figure out near-doubles, such as using 6+6=12 to solve 6+7. A simple story problem about Sam picking apples is also included. Part B contains five fill-in-the-blank equations testing flexible thinking with unknowns.

This sheet stretches young mathematicians toward first-grade-ready problem-solving and reasoning skills.
