Title: Rain Drops
Description:

In this lesson, students will examine the amount of annual and seasonal rainfall in four cities to compare decimals to the hundredths place. Students will add and round digits to the thousandths place. Students will utilize technology by navigating to a specific United States climate website to get relatively current and accurate data.

This unit was created as part of the ALEX Interdisciplinary Resource Development Summit.

Title: Natural Resources Shared Naturally
Unit Plan Overview: Natural resources provides what living things need to survive and thrive. This unit explores the transfer of energy throughout the food chain, investigates the amounts of rainfall in a region, examines the patterns of Native Americans settling adjacent to water, and guides students as they design animals that would survive in a wet biome. The math, science, history, and language arts lessons included are strong enough to stand alone, but when taught simultaneously, strengthen each of the 5th grade standards. This unit was created as part of the ALEX Interdisciplinary Resource Development Summit.

Title: Half Court Shot
Description:

Half-Court Rounding is a game in which students try to score as many points as possible by rounding numbers to the nearest ten, hundred, or tenth. Students can try any kind of shot within the game and have 90 seconds to score as many points as possible and beat their opponent. If they answer incorrectly, the student misses the shot. Students can also choose a two-player game where they can play a friend or classmate.

This activity results from the ALEX Resource Gap Project.

Title: Grade 5 Mathematics Module 1, Topic C: Place Value and Rounding Decimal Fractions
Description:

In Module 1, Topic C, students generalize their knowledge of rounding whole numbers to round decimal numbers to any place. In Grades 3 and 4, vertical number lines provided a platform for students to round whole numbers to any place. In Grade 5, vertical number lines again provide support for students to make use of patterns in the base ten system, allowing knowledge of whole-number rounding (4.NBT.3) to be easily applied to rounding decimal values (5.NBT.4). The vertical number line is used initially to find more than or less than halfway between multiples of decimal units. In these lessons, students are encouraged to reason more abstractly as they use place value understanding to approximate by using nearest multiples.

Naming those nearest multiples is an application of flexibly naming decimals using like place value units. To round 3.85 to the nearest tenth, students find the nearest multiples, 3.80 (38 tenths 0 hundredths) and 3.9 (39 tenths 0 hundredths), and then decide that 3.85 (38 tenths 5 hundredths) is exactly halfway between and, therefore, must be rounded up to 3.9.

Title: Rounding Decimals StudyJam
URL: https://studyjams.scholastic.com/studyjams/jams/math/decimals-percents/rounding-decimals.htm
Description:

In this interactive activity, students will be led through steps to round decimals to the nearest whole number using a number line. There are teaching activities as well as practice activities available. A handout that reviews the steps taught during the activity can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
