In this topic, students will:
use patterns and the properties of multiplication to calculate a product when multiplying by a power of 10; use whole number-number exponents to write powers of 10
read and write whole numbers using standard form, expanded form, and number names
represent decimals to thousandths as fractions and fractions with denominators of 1,000 as decimals
read and write numbers with decimals through thousandths using standard form, expanded form, and number names; identify equivalent decimals
use place value to compare decimals through thousandths
use place value to round decimals to different places
Vocabulary:
Exponent - the number that tells how many times a base number is used as a factor.
Power - the product that results from multiplying the same number over and over is a power of that number.
Base - when a number is written using exponents, the base is the number that is used as a factor.
Value - the place of a digit in a number tells you its value.
Expanded form - a way to write a number that shows the sum of each digit multiplied by its place value.
Thousandth - one out of 1,000 equal parts of a whole.
Equivalent decimals - a decimal that names the same part of a whole.
At-home Practice:
This game has a decimal mat that is used with it. You do not need it! You can draw lines a scrap piece of paper to represent the boxes from the mat.Â
