This lesson does not use an algorithm or cute rhyme to teach students to round. Instead they use number sense and place value practice to understand the concept of rounding decimals.
5.NBT.4 Use place Value understanding to round decimals.
“This standard refers to rounding. Students should go beyond simply applying an algorithm or procedure for rounding. The expectation is that students have a deep understanding of place value and number sense and can explain and reason about the answers they get when they round. Students should have numerous experiences using a number line to support their work with rounding.”
Round 14.235 to the nearest tenth.
Students recognize that the possible answer must be in tenths thus, it is either 14.2 or 14.3. They then identify that 14.235 is closer to 14.2 (14.20) than to 14.3 (14.30).
I developed this lesson and student work pages to practice the common core standard which focuses on understanding.
