Students use multiplicative comparison statements to explain that a digit in one place represents 10 times as much as what it represents in the place to the right. Students notice how digits of a number shift when they multiply or divide by a power of 10 and express a power of 10 in exponential form. Then students find products and quotients by using powers of 10 and convert metric measurements from larger to smaller units.

Family Math Topic A

Students build fluency with multiplying multi-digit numbers by using the standard algorithm. They use place value understanding to visualize the decomposition of factors while they multiply a single digit at a time by another single digit in the standard algorithm.

Family Math Topic B

Students use methods based on place value to find quotients of whole numbers with up to four-digit dividends and two digit divisors. They estimate quotients, then use tape diagrams, area models, and vertical form to record quotients and remainders. 

Family Math Topic C

Students use methods based on place value to find quotients of whole numbers with up to four-digit dividends and two digit divisors. They estimate quotients, then use tape diagrams, area models, and vertical form to record quotients and remainders. 

Family Math Topic D

centigram

A centigram is a metric unit for measuring weight. A gram is 100 centigrams. A large ant weighs about 1 cg. (Lesson 5)

centiliter

A centiliter is a metric unit for measuring capacity or liquid volume. A liter is 100 centiliters. (Lesson 5)

dividend

In a division expression, the number being divided by another number is the dividend. For example, in the expression 18 ÷ 3, the dividend is 18. (Lesson 12)

exponent

An exponent represents how many times the same number is used as a factor. (Lesson 3)

exponential form

A number with an exponent is in exponential form. (Lesson 3)

kiloliter

A kiloliter is a metric unit for measuring capacity or liquid volume. A kiloliter is 1,000 liters. (Lesson 5)

milligram

A milligram is a metric unit for measuring weight. A gram is 1,000 milligrams. A small feather weighs about 1 mg. (Lesson 5)

millimeter

A millimeter is a metric unit for measuring length. A meter is 1,000 millimeters. (Lesson 5)

power of 10

A number that can be written as a product of 10s, or as a 10 with an exponent, is a power of 10. 100 is a power of 10. (Lesson 3)
