Decimal Fractions

Module 6 Lessons:

Topic A: Exploration of Tenths

Lesson 1: Use metric measurement to model the decomposition of one whole into tenths.
Lesson 2: Use metric measurement and area models to represent tenths as fractions greater than 1 and decimal numbers.
Lesson 3: Represent mixed numbers with units of tens, ones, and tenths with place value disks, on the number line, and in expanded form.

Lesson 4: Use metersto model the decomposition of one whole into hundredths. Represent and count hundredths.
Lesson 5: Model the equivalence of tenths and hundredths using the area model and place value disks.
Lesson 6: Use the area model and number line to represent mixed numbers with units of ones, tenths, and hundredths in fraction and decimal forms.
Lesson 7: Model mixed numbers with units of hundreds, tens, ones, tenths, and hundredths in expanded form and on the place value chart.
Lesson 8: Use understanding of fraction equivalence to investigate decimal numbers on the place value chart expressed in different units.

Lesson 9: Use the place value chart and metric measurement to compare decimals and answer comparison questions.
Lesson 10: Use area models and the number line to compare decimal numbers, and record comparisons using <, >, and =.
Lesson 11: Compare and order mixed numbers in various forms.

Lesson 12: Apply understanding of fraction equivalence to add tenths and hundredths.
Lesson 13: Add decimal numbers by converting to fraction form.
Lesson 14: Solve word problems involving the addition of measurements in decimal form.
