4th Grade Makes Over 100,000


In fourth grade, we jump from working with numbers in the thousands to working with numbers in the millions!  Those are some big numbers!  To help us better conceptualize large values, we used thousands cubes to show the framework of a million.  We discussed how each row of ten thousand cubes was equivalent to 10,000.  We found that ten rows of ten thousand cubes equaled a million!  This activity allowed us to explore the concept of the power of ten (10 ones = 1 ten, 10 tens = 1 hundred, 10 hundred = 1 thousand, etc.), and practice creating three forms of a number.  Using these manipulatives helped our students have a concrete visual of number value, which we will continue to use as we work on breaking down and building numbers.
