Understanding Patterns in Number Sequences

This video tutorial covers a second-grade math lesson focused on filling in a hundreds chart using place value patterns and mental math. The lesson begins with an introduction to the hundreds chart and progresses to using place value patterns to fill in missing numbers. Students practice adding by ones and tens, and explore more complex number patterns. The lesson concludes with identifying patterns and an assessment task.
