Lesson Plan Description
This half day lesson plan is broken down into 3 separate segments (30-60 minutes each) addressing Numbers in Base-Ten: Rounding Decimals (5.NBT.4). These lessons include: key place value and rounding vocabulary, helpful student notes for reference, guided and independent practice of concepts, and a BINGO game to reinforce the concept of rounding decimals.
- Segment 1: students will round a decimal number to the nearest whole number (ones place) by using a horizontal number line and use place value understanding to round decimal numbers to the nearest whole
number, tenth, and hundredth (1/10, 1/100).
- Segment 2: students will use place value understanding to round decimal numbers to the nearest whole number, tenth, hundredth, and thousandth places (1/10, 1/100, 1/1000) and to round decimals in real-life word problems.
- Segment 3: students will round decimal numbers, including in the form of money, to the nearest whole number, tenth, hundredth, and thousandth (ones, 1/10, 1/100, and 1/1000) place.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
