Addition by Regrouping

The video tutorial explores different methods of counting and adding numbers using examples of chicks and rabbits. Sam and Sela demonstrate two different addition methods: Sam uses direct addition, while Sela forms groups of 10 for quicker calculation. The video compares these methods and applies the group of 10 method to another example with rabbits, highlighting the efficiency of forming groups of 10 for addition.
