We use this lesson plan to guide students to analyze the sounds and spelling of the words for numbers. This will help them as they begin to write checks, with both the numbers and the words for the amounts written on the same check.
It will also help them to understand why English Language Learners might have difficulty learning to say the words we use for numbers. Since this is a PowerPoint file, you as the teacher have the ability to add pronunciations for numerals in other languages that you (or your students) may be familiar with.
