Hello everyone! I'm interning in a kindergarten class this semester but one of my classes requires me to make lesson plans for an older crowd (1st-3rd grade). My topic that I must make a math lesson for is multiplication. What grade is that generally introduced in? I subbed in a 3rd grade class yesterday and they were reviewing addition and subtraction facts, along with 'doubling numbers' (which is ultimately simple mulitiplication). If I make a lesson plan for 2nd grade, is this unreasonable? Can this age grasph the concept? And should I only use low multiplication facts (1-5? 1-10?) Thanks for any help you can suggest!
