Lesson Plan Description
This half day of lesson plans is broken down into 4 separate segments (30-60 minutes each) addressing: Measurement & Data, Numbers in Base Ten and Operations and Algebra. These lessons include: categorizing based on number values, comparing numbers using (<, >, & =), adding and subtracting using mental math, and solving addition word problems.
- Segment 1: students will draw a chrysanthemum flower and write their name above it.
- Segment 2: students will count letters in their names, categorize their name based on that number, and analyze data determining which names have more letters, less letters, or the same number of letters.
- Segment 3: students will add and subtract using mental math strategies and solve addition word problems using addition strategies.
- Segment 4: students will add and subtract using mental math strategies while playing the game “Steal the Bacon”.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
