  1. Module 2 Lesson 10 • Multiply decimal fractions with tenths by multi-digit whole numbers using place value understanding to record partial products.

  2. Common Core Standards 5.NBT.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
