Understanding Tenths and Hundredths

This video tutorial teaches how to add decimals using a 10x10 grid. It begins by explaining how each square in the grid represents a hundredth of a whole. The tutorial then demonstrates how to represent and add decimals, specifically 24 hundredths and 58 hundredths, by shading squares on the grid. The process involves shading columns and individual squares to visualize the addition. Finally, the video concludes by calculating the total shaded area to find the sum of the decimals, reinforcing the concept of decimal addition using visual aids.
