Place Value

I thought the LPU for teaching place value was a fun and new way of learning place value. Though to be honest, I was very confused at what we were learning to teach our students in place value. I am confused on why we need to teach students the base 3 and base 5 values if we only really use base 10 to teach math problems. Maybe I am just confused on part of the lesson and don't remember being taught any of base 3 and base 5 in my elementary school days. However, I thought the using the manipulatives in the game was a fun way to understand addition and subtraction. It is a great visual and hands-on way to really show your students how to "steal" in subtraction and not "borrowing." I also think it is a better term to use "steal" instead of "borrow" so that students understand that the number column is not getting anything back. I also really liked getting to see using the unit blocks in one of the previous lessons for addition and subtraction. These are some learning manipulatives I would like to use in my future classroom to help explain math as it is very confusing for some students.
