Title: Grade 4 Mathematics Module 6, Topic A: Exploration of Tenths
Description:

In Topic A, students use their understanding of fractions to explore tenths. In Lesson 1, students use metric measurement and see tenths in relation to one whole in the context of 1 kilogram, 1 meter, and 1 centimeter.

Students will:

• use metric measurement to model the decomposition of one whole into tenths.
• use metric measurement and area models to represent tenths as fractions greater than 1 and decimal numbers.
• represent mixed numbers with units of tens, ones, and tenths with number disks, on the number line, and in expanded form.

Title: Grade 4 Mathematics Module 6, Topic B: Tenths and Hundredths
Description:

In Topic B, students decompose tenths into 10 equal parts to create hundredths. In Lesson 4, they once again use metric measurement as a basis for exploration.

Students will:

• use meters to model the decomposition of one whole into hundredths. Represent and count hundredths.
• model the equivalence of tenths and hundredths using the area model and number disks.
• use the area model and number line to represent mixed numbers with units of ones, tenths, and hundredths in fraction and decimal forms.
• model mixed numbers with units of hundreds, tens, ones, tenths, and hundredths in expanded form and on the place value chart.
• use understanding of fraction equivalence to investigate decimal numbers on the place value chart expressed in different units.
