This lesson focuses on teaching students how to add up to two 3-digit numbers using place value charts and counters.
Regrouping in addition occurs when the sum of the digits in a column is greater than 9. It involves carrying over or exchanging values between places.
The methods used in this lesson include introducing the place value chart and counters model, teaching students to add from right to left, and using regrouping when necessary.
In this interactive math lesson, students will develop their subitizing skills by visually recognizing patterns and determining the total number of objects up to 10. Through engaging activities such as counting stars, identifying patterns in the sky, and feeding rabbits, students will strengthen their ability to quickly recognize quantities without counting. They will also practice using number relationships to find missing numbers. The lesson concludes with an exit slip to assess students' understanding. Optional additional practice problems are provided for further reinforcement.
