1. The document outlines a lesson plan for teaching numbers up to 20 to first grade students through reading a digital book and using manipulatives like cups and beans. 2. The teacher will introduce the book, read it once with students, and have volunteers demonstrate counting cups with written numbers. 3. Students will then individually write and say a number, find and label the corresponding cup, and count out that many manipulatives to represent the number. 4. Assessment involves checking students' writing and counting of numbers and manipulatives to determine if they can represent numbers up to 20. Accommodations for English language learners are provided.
