Lesson Plan Description
Fourth Grade half day of math lesson plans containing 3 separate segments (30-60 minutes each) addressing Numbers in Base-Ten: rounding whole numbers to the hundred-thousands place (4.NBT.3). These lessons include: key place value and rounding vocabulary, helpful student notes for reference, guided and independent practice of concepts, and a game to reinforce the concept of rounding whole numbers through the hundred-thousands place to any place.
- Segment 1: students will use place value understanding to round whole numbers to the nearest 1,000, 10,000, and 100,000. They will round to the nearest 1,000, 10,000, and 100,000 on a vertical number line.
- Segment 2: students will look for rounding challenge cards around the classroom. Each card has a varied difficulty level and point value. Students are trying to solve as many problems as they can correctly to earn points in the challenge.
- Segment 3: students will spin a wheel to create a 6-digit number. They will then spin a second wheel to determine which place to round their number to. Finally they will compare the two numbers to determine who has the larger number.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
