Parent info for December

Students extend their knowledge of exponents from Grade 5 as they strengthen their understanding of the related vocabulary (base, power, exponent, cubed, and squared) and move from whole number bases to bases written in fraction and decimal form.

After studying exponents, students will learn more about the order of operations and how it is used to evaluate various numerical expressions by examining operations in terms of how powerful they are. You can expect to see homework that asks your child to do the following:

▪ Write a number in exponential, expanded, and standard form.

▪ Explain why a whole number base raised to a whole number exponent gets larger, while a fractional base raised to a whole number exponent gets smaller. ▪ List all the powers of 3 and 4 that evaluate to any number between 3 and 1,000.

▪ Describe the advantage of exponential notation (rather than a multiplication expression) if all the factors are the same.

▪ Explain the difference between expressions using their knowledge of exponents. For example, 3x and x3 are different because if x has a value of 2, the value of 3x is 3(2), or 6, and the value of x3 is 2 × 2 × 2, or 8.

▪ Evaluate an expression using the order of operations.
