Big Ideas: The exponent of a number tells us how many times to use that number in a multiplication sentence. Exponents provide a structure for writing larger numbers. A new concept in Grade 5 is the use of whole number exponents to denote powers of ten. Students need experiences working with connecting the pattern of the number of zeroes in the product when they multiply by powers of 10. Students need to be provided with many opportunities to explore this concept and come to this understanding. This concept builds towards subsequent work with operations and fractions. Vocabulary: exponent, powers of ten, multiplication, product, expanded form, standard form
