Formative Assessments

Rounding To The Nearest Whole Number:

Students are given four numbers and asked to round each to the nearest whole number and to explain their reasoning.

Type: Formative Assessment

Rounding To The Thousandths Place:

Students are given four numbers and asked to round each to the nearest thousandth and to explain their reasoning.

 

Note: Three of the numbers are decimals to the ten-thousandths place and one number is to the hundred-thousandths place. If students are not ready for rounding larger decimals to the thousandths place, use an alternate MFAS task that rounds to the hundredths, tenths, or whole number.

Type: Formative Assessment

Rounding To The Tenths Place:

Students are given four numbers and asked to round each to the nearest tenth and to explain their reasoning.

Type: Formative Assessment

Shopping for Produce:

Students are asked to round numbers given in a context to the nearest hundredth.

 

Note: The decimals students are rounding in this task extend past the thousandths place. If students are not ready for rounding larger decimals to the hundredths place, use an alternate MFAS task that rounds to the hundredths, tenths, or whole number.

Lesson Plans

Currency Craze!:

If I travel to Italy, can I buy a raspberry gelato with a $5.00 bill? Students will understand that other countries use currencies different from the United States, and that when visiting those countries, exchange rates are used to determine the value of the United States dollar (USD). This lesson integrates Mathematics with Social Studies as the students apply their knowledge of decimals and basic operations with their passports for a real-world application.

Type: Lesson Plan

Estimating Decimal Products:

In this lesson, students will learn to estimate decimal products using different strategies to arrive at compatible numbers. They will learn that estimates will vary depending on the strategy chosen and that the closer the compatible numbers are to the actual factors, the closer the estimate will be to the exact answer. Students will also learn that estimation is used to solve problems that don't require exact answers and to check exact answers for reasonableness.

Type: Lesson Plan

The 20 Second Game:

This is a game students will love to play to improve their understanding of estimating decimal products and increase speed when finding these estimations. The game can be modified to practice estimating products of whole numbers, quotients of whole numbers, and quotients of decimals.
